E. Milchert et al., BY-PRODUCTS OF ETHOXYLATION OF DIETHYLETHANOLAMINE AND ITS SOLUTIONS IN METHANOL, Organic process research & development, 1(5), 1997, pp. 379-383
Major products and by-products of the ethoxylation of diethylethanolam
ine and its solutions in methanol have been identified, Through gas ch
romatography and mass spectrometry, it has been found that by-products
correspond to ethyldiethanolamine and its succeeding ethoxylates, In
methanol ethoxylation, diethylethanolamine acts as a catalyst and also
itself undergoes ethoxylation, forming two types of products.
