Reaction Steps
When 0.224 mol of NaOH in 1.11 mole of water was mixed with 1 mol of 5-methyl-N-(2-hydroxypropyl) oxazolidin-2-one (MHPO) and the mixture heated at 95° C. for five hours there was obtained about a 13 percent conversion of the MHPO to diisopropanolamine (DIPA). After 29 hours at 95° C. only 13.9% conversion was achieved. Following the addition of an additional 0.22 mol of NaOH to the reaction mass, continued heating at 95° C. resulted in a conversion of only about 25%. This experiment establishes that the reaction to convert one mol of MHPO to its component (1 mol diisopropanolamine) requires two (2) mol NaOH. A white precipitate formed during the process and was identified by IR analysis as Na2CO3.
