Hetcher, week of 27 July

The second week of research has been completed, and I’ve achieved a few things. The decision was made to synthesize all of the 1-alkyl-2,3-dimethylimidazolium bis(trifluoromethylsulfonyl)imide ionic liquids myself. We’re going to try to make between 20 and 25 mL of each (butyl, hexyl, octyl, and decyl), to best compare with the data gathered last summer, on the non-methylated IL’s of the same system. Come to think of it, I’m not certain that the previous data uses TFSI as the anion. That will need to be inquired upon. The synthesis will start as soon as the materials, having been ordered, show up. In the meantime, I’m going to refine the procedure, to make certain that things will go smoothly. The proposed Sythesis will vary based on how much exactly we want, but will continue to be updated anyways as I prepare to move up to the Orgo floors and get my hands dirty. I’ve created a document in Excel that will allow me to use trial data on the yield to refine how much of the product to use. Even though we’re going with the cheaper option, science is expensive.

The FTIR is still not working, and probably will continue to sit there until we hear back from Bruker. The main issue seems to be that the scanner was left on while the pressure in the air bearings was depleted. This meant that the motor was working overhard to push the scanning mirror, and burned itself out. We’ll wait to see if that’s really the case, and what the Bruker techs recommend. However, I was able to successfully line up the laser with the IR source, from the point of view of the globar. I’m hopeful that this means other parts can be pulled back from the grave as well.

In total, it was a decisive week, and steps were made towards compiling data. The FTIR is on hold until more experienced thoughts are shared, but we’re this much closer to explaining that which no one yet has.
