Recrystallizing can be a be-yatch

I’m sitting in my library in the comfy chair with Linus sprawled on my lap and Lucy sleeping on my headrest. I suspect the little ones missed me while I was away re-learning organic chemistry. Don’t worry, babies, only one more week of classes!

As an adjunct professor for Indiana University thanks to ACP (Advance College Project), I can take classes at IU for free. And the chemistry department offered a 2-week survey of organic chemistry with us ACP teachers in mind. So I figured, free graduate credits that would be useful and accomplished quickly? Hell yah!

Well… it would be free if I didn’t live 3 hours from the Bloomington campus. So I have decided that my big summer trip is to take this class. The dorm room rang up to over $500. There’s a $120 tech fee/lab fee that won’t be reimbursed. And 12 hours of driving for the course = gas expenses. Oh, and going out to eat daily doesn’t help.

Other than the fact that the dorms were air conditioned (woohoo) I knew nothing about them. Fridge? Microwave? Towels? Well, turned out towels were provided, but the rooms have no fridges. (There’s a microwave for the floor that I could use, however.) In anticipation of no fridges, I brought my cooler and some milk and yogurt. And it wasn’t until midweek after I purchased a bag of ice that I discovered the ice machine on the ground floor of the dorm. Heh.

The course has been great. Kate Reck is the instructor and she’s the one who trained us at the ACP training in June. There are 10 of us students but I’m the only newbie to ACP. A few of the students took Kate’s class that she offered last summer on analytical chemistry. I’m relearned a lot, and there are things I’m pretty sure that I’m learning for the first time.

I already talked about our first lab. We do labs on Tues & Thurs (and need long pants – it’s bloody hot this week and will be hotter next!) Our Thursday lab was on extraction and recrystallization. We were given a container with three unknowns – an impurity to be filtered out, an organic base, and an organic neutral substance.

We dissolved the compounds in diethylether and then filtered out the charcoal. Next, we added sodium hydroxide to make the acid soluble in water and used a separatory funnel to separate the two solutions. The neutral compound was separated from the ether by a rotovap (nifty device that evaporates volatile solvents by spinning & using a vacuum), which was our second time using it. The acidic solution was returned to an acid, whereby it precipitated out of solution.

We decided to just recrystallize the acidic compound, so my partner, Rich, determined the melting point of our neutral compound. We were just .2°C over the accepted value for naphthalene (which was the correct compound). Meanwhile, I was working on recrystallizing our carboxylic acid. The super saturated solution (I was using ethanol as the solvent) was room temp, so I put it in the ice bath, and it immediately all fell out of solution. Bugger.

No matter, reheating the flask allowed me to redissolve the solution. And this time I went even slower. I was adding cold water to a room temp water bath, when Kate stopped over. She suggested scratching the flask bottom with a scoop, and proceeded to do it. Whereby the crystals came out in a big clump once again. We both about fell over with laughter. (The things that chemists find amusing).

So no idea if we would have gotten the right melting point for our acid. We were basically out of time by then, so my partner and I cleaned up and put our goggles away for another week.

One of my intentions when taking this course was to eat at the nifty ethnic restaurants near campus. Only the weather conspired against me. It was so hot at the start of the week that I went to the student union Mon & Tues. Wednesday, four of us went to Nick’s for lunch, where I had the nicest cheese steak I’d ever had. See, at Nick’s they don’t chop the steak up, it’s just laying on your hoagie. Nice and medium rare and very yummy with the provolone and onions.

Thursday, Kate invited those of us who could to join her and her hubby for supper at their favorite Mexican place for supper. So I had yogurt for lunch and joined Kate, Bill, Marvin, and Kevin at La Torre near the Kroger on College Mall road. I had a combo meal with a carne asada, two chicken flautas, and a spicy chile relleno. Very yummy and excellent company.

And my night life on Thursday wasn’t done yet. It turns out that the Indiana Festival Theater just started their summer run of The Comedy of Errors. So Wednesday night, I purchased a balcony seat for the show. As soon as I’d driven back to the dorm, I walked to the theater and sat in the middle of the balcony to watch the show. It was excellent. The set was tiny, but very fun to look at. The cast did a great job (though both Antipholus’s stumbled on a few lines here & there) and I loved the addition of an accordion player separating the scenes. They had a queen instead of the duke, which was fine too. I laughed a lot (as did the rest of the audience) and enjoyed myself. The walk back to the dorm was also very pleasant.

Today, most of the class went along with Kate to Amol India for Indian Fud. They had a nice buffet and I ate well. And then Kate footed the bill for us! Nice lady! (And a very good teacher, too.)

Class let out a little early today, which allowed me to leave campus a bit earlier and I got home before 7pm. Been hanging out with the kitties most of my time here, downloading free software which I get with my IU ID. Free Adobe CS 5.5, free ChemBioDraw, free Lynda.com (with the exercise files!) It’s all good!

Tomorrow I’m off to watch HP7.2 with the parental units. Am looking forward to this. And I think Sunday I wanna catch some World Cup (I’ve missed most of it this time around, alas). And then Sunday night, back to Indiana!

Murder for Two

Today was another great day hanging out with judiang and elsaf. We started off with Dim Sum at Three Happiness in Chinatown. Yum!

After we returned from brunch, we went to Judi’s pool and spent some quality time reading & wading. Very relaxing.

But after that, we zipped off to Navy Pier to see a new musical, Murder for Two. It had a cast of thousands played by two men. Well, not thousands, but several. And lots of piano playing. It was quite entertaining, very funny, and the piano playing was brilliant.

After the excellent show, we went to Riva, a hoity-toity seafood place at Navy Pier. Great service, great food, and decadent desserts. I couldn’t make up my mind on what to have, so I had a set of 4 small plates. Grilled shrimp, crab salad, pappadew peppers (blue crab & Brie in peppers & fried in a ball), and artichoke beignet (artichoke & cheese also in a fried ball). All were tasty with the artichoke winning and pepper balls in second place. Then dessert was also a combo – Chocolate Fantasia. This was chocolate gelato, chocolate flour-less cake, and chocolate mousse. All very yummy. And the chocolate ice cream had salt in it just added to the intensity of the flavor. Oh, and I also had a mojito. We won at supper.

We had pondered staying there to watch the Saturday fireworks, but then later decided that seeing them from Museum Campus would be almost as good (and less crowded). So we returned to Judi’s flat and watched another episode of Game of Thrones.

But soon it was time for walking to Museum Park. Judi wanted to make sure I was safe walking in her big city at night, so she came along as my protector. We stopped by the planetarium and waited. The fireworks, as usual, were impressive.

Once we returned home (with a slight detour) we watched another Game of Thrones (5 eps down, but we don’t think we’ll get ’em all watched before we leave Monday).

Jersey Boys are Boss!

As we had, indeed, planned, we wound up going to Ma & I for supper. We all ordered sushi as an appetizer (me getting California roll – yum!). judiang and I both ordered tofu pad thai and elsaf ordered shrimp lad nar. Very yummy. Then we cabbed it to Bank of America Theater to watch Jersey Boys.

I’ve heard music by Frankie Valli and the Four Seasons but didn’t always know it was them. But I recognized more than half of the songs in the musical and enjoyed it all. A very fun musical with lots of good music. I did miss some of the dialog in the show (but heard more than Judi, who figures she understood 3% of the dialog). While watching it, I kept wanting to get on Wikipedia to read more about Frankie Valli et al. (Joe Pesci? Really! Wow!) I am SUCH a geek. But I feel a little vindicated cuz Judi admitted the same. 🙂

After the show, we took a cab back to where we’re picked one up before the show. Cuz we had some ice cream to be eating! Good ol’ Marble Slab is open late, so we got ice cream for the walk back to Judi’s apartment. I had chocolate swiss and pistachio. Yum!

Now I’m watching Olympics and we’re all geeking. I have a couple of photos from our bike trip today, which I shall post under the LJ cut.

We paused along Lake Michigan to turn around and head back. We’re on rental bikes.

And so it begins…

Now that many people are done with their Christmas, I am finally beginning mine. Sure, I’ve been to the extended family gatherings, but since Amy & Rachel weren’t there, they don’t count. However, today I drove Oop North to Detroit and am at elsaf‘s for a few days. We exchange gifts tomorrow and later in the week, Amy & Rachel come to Ohio for our family Christmas. So let’s hear it for Christmases that last all week!

I got the Elsa’s safely and on time this morning. And shortly after, I was sent off to pick up judiang from the Metro airport. Eep! But I drove there & back just fine. And I even remembered to pick up Judi!

We did a short shopping spree at Best Buy where I wasn’t allowed to be where Judi was (and apparently neither was Elsa), but as I had to park the car (somewhere in the vicinity of the store – I think I was only 17 blocks away) I managed to avoid her. While in the store, I noticed I’m getting slack in my DVD collecting. Season 4 of Bewitched and the final seasons of Dangermouse are now on DVD. Looks like I know what I’ll be getting myself after the new year comes!

After a bit of geeking back at the house, we headed off to supper at Sy Thai Shores restaurant. We started with the appetizer sampler – spring rolls, shrimp thingies, and crab rangoon. I had pad thai with tofu (hmmmm, couldn’t think of anything original, eh trina?), Elsa got the drunken noodles, and Judi got the orange duck. For dessert, Judi and I opted for coconut ice cream (yum!) and Elsa got the Thai version of banana cake. Everything was yummy!

To top off our evening, we headed off to the Fisher Theater to see Spamalot. I bought a $20 program magically (well, Judi swears she never saw me buy it) and we found our seats. We had great seats on the mezzenine. Nicely done, Elsa! The show was funny and the songs quite entertaining. And a lucky guy in the audience got to leave with a miniature Holy Grail. Heh.

On our way back, Elsa drove by Lakeshore Drive (Chicago doesn’t have the monopoly on Lakeshore drives) so we could look at the Christmas lights. Some pretty swanky houses out there with even swankier Christmas lights. If we get the gumption, tomorrow we’ll go again and Judi will try to get photos.

Well, now that I’m nicely settled, Judi is insisting that I make her an amaretto sour. Such a taskmaster is our Judi…

Yup, it’s Autumn! And Trina’s trying to become more social…

Since the first day of Fall, I’ve been wondering if maybe Summer had decided to stay & give Autumn a miss. But as of yesterday, it’s actually seemed like Autumn – yay! Walking home from school yesterday, I saw steel gray skies, some trees (the maples, of course) starting to turn, and encountered a lovely cool breeze that never let up. There’s my favorite season! Back again!

I notice that it’s been over a week since I last wrote in my journal. Wow – now this was what I figured would happen after the first couple of weeks of having my LJ. But it has taken almost two years to get to this point. I blame my lack of posting to my City of Heroes addiction. Since getting my level 50 hero, I’ve been creating and playing lots of other heroes and so my drive to play has increased. If it wasn’t so much fun, I’d be worried. 😉

Anyhoo, I’m doing what I can to get back into my rather limited social life. Last night, I went off to the Fisher’s for homemade pizza & folks to chat with. Today it’s off to see My Fair Lady at the Schuster Center in Dayton. My aunt, cousin, mom & I are going to see it. Then going out for dinner afterward. Apparently this show is getting good reviews. A show not to be missed. Nice!

And to further my socializing, on Thursday I’ll be going on a Light the Night walk with a coworker and lots of strangers. It sounded fun, I’ll get to meet his fiancee, and it’s at the Fraze Pavilion, one of the nice venues in the Dayton area. Now I know lots of you are probably donated out with the Katrina relief funds and whatnot, but if you’d like to contribute a little ($5? $10?) to the Light the Night walk, you can do so at this website. It’s in aid of Lymphoma & Leukemia research. (My co-worker’s mother has lymphoma. A friend of mine in high school died our junior year because of leukemia. These diseases touch a lot of us and our loved ones. Please give something if you can. If you can’t, that’s OK too!)

So, perhaps with these small steps at socializing, I might get out of my antisocial funk I’ve been in for the past couple of weeks. And maybe even post a bit more to LJ!
