Title: Ethanolamine purity?
Post by: del72 on July 16, 2003, 09:30:00 PM
My friend is going to be working on a batch of 2ci in the next week here. He went to order the ethanolamine to hydrolyze N-(2-(2,5-Dimethoxyphenyl)ethyl)phthalimide. Is 98% pure ethanolamine pure enough for this reaction? The 98% is like WAAAYYY cheaper than the 99+, so it would be ideal.   I was assuming that is was pure enough and he was going to just order it, but I told him to hold off until I get a second opinion.

thanks ahead of time!

Yes, it's cheaper.  Why do you need the amine for a hydrolysis reaction?
