Triethanolamine → L-Glutamic acid, N-(1-oxododecyl)-, compd. with 2,2',2''-nitrilotris[ethanol] (1:1)

Participants

Reaction Steps

To the resulting liquid, triethanolamine was added so as to convert 50% of the carboxyl group of N-lauroyl-L-glutamic acid to its salt, and further pure water was added thereto so as to make a solid content 30% by weight. The liquid was mixed under stirring to obtain an aqueous solution of triethanolamine N-lauroyl-L-glutamate. A yield (as acid) of N-lauroyl-L-glutamic acid, a tertiary butanol concentration and a free fatty acid content were found to be 90.5%, 60 ppm by weight and 8.3% by weight, respectively.
