I am looking for a way to purify an alkyl halide from a pyridine solution. I started with 0.02 grams of pyrene 1-methanol and added to it 20 mL pyrene and 200 uL of SOCl2 at room temperature hoping that the substitution reaction would happen. The solution has been sitting for a day at room...

If I have a end alcohol attached to a carbon chain, what would be a reaction or synthetic pathway that can be done to transform the alcohol to an alkyne? Thanks for your input.

If I have some polystyrene and want to analyze it using FTIR for trace elements, what type of sample preparation should I look into? If I were to use a liquid sample preparation, I wouldn't be able to use say, toluene, because the two structures are similar, correct (aromatic)? On the other...

Below is the picture I promised.

I have shown a picture of our current ellipsometry setup. The sample is placed in the center. Polarized light comes in from the left barrel, reflects off the sample, and enters the barrel on the right. What I'm looking to build is a cover/chamber this that covers the sample but does not affect...

OK, so I have shown a picture of the current setup. The sample is placed in the center. Polarized light comes in from the left barrel, reflects off the sample, and enters the barrel on the right. What I'm looking to build is a cover/chamber this that covers the sample but does not affect...

I have a polymer sample and am interested in qualitatively determining the sulfur (sulfate group) content. Which analytical technique should I consider using? This polymer is not soluble in water but is soluble in THF and toluene. Thanks.

Hi guys, I am interested in designing a chamber that is either purged with nitrogen gas or vacuum sealed that encloses a thin film sample. The method of analysis is via ellipsometry. (My knowledge of optics is extremely limited but know that ellipsometry measures some shift in polarization...
