Since just about this time last week, I've been trying to write up the results of my summer internship. So far, I've reframed them to the point where it doesn't sound like I wasted the time I spent there. I do still have four, or perhaps five, different ways not to perform the reaction I was studying. But I'm milking all the data out of them that I possibly can, and that's got to be good for something.
All of the product-extraction end of the process will be generalizable to Doing It Right, whatever that turns out to be. And I've been exicted about this for several days, because I think I can modify it in such a way as to get rid of the benzene. The greatest benefit here is that I wouldn't need to expose myself to a highly toxic substance. The fact that the new version uses ordinary lab hazards like chloroform and toluene is just circumstantial icing - I should be able to use one of the rotavaps that reliably works, rather than the not-quite-broken hazmat one.
Yesterday, though, I spent in the frustrating search for figures that I'm not sure anyone has reported. The reaction liberates kind've a lot of energy, and it'd be nice to be able to calculate how much. But that requires knowing the standard enthalpies of all reactants and all products, in the same phase. (Ideally liquid, 'cause that's what I'm actually using.) So far, that number for my product only appears to be available for the substance as a gas.. And without the corresponding data point for enthalpy of vaporization. Now that I've thrown so much time at it, though, I'm reluctant to not say anything on the subject.

Monday. Reactions still not working. Another leg fell off. I need more electric power. Couldn't find the Necronomicon at the library. Someone must have it checked out.
