J. Poskrobko et al., BY-PRODUCTS OF ETHOXYLATION OF SIMPLE ALCOHOLS IN THE PRESENCE OF TRIPROPYLAMINE, Journal of chemical technology and biotechnology, 67(1), 1996, pp. 84-88
Ethoxylation of simple alcohols such as methanol, ethanol and butanol
in the presence of tripropylamine, in addition to the main reaction pr
oducts, results in by-products from tripropylamine and ethylene oxide.
This side-reaction consumes tripropylamine, forming dipropylamine eth
oxylates and alcohol ethoxylates. These compounds remain in the produc
t and influence the commercial properties of alcohol oxyethylates.
