Description

Polyoxyethylene alkylamine is usually prepared by the reaction of alkylamine with ethylene oxide. The product becomes yellow or brown according as the additien of ethylene oxide proceeds.<BR>This coloration has been considered te be caused by aeetaldehyde centained in ethylene oxide as a minor impurity. However, it was observed that tertiary amine, polyoxyethylene alkylamine itself, acted as the catalyzer of rearranging ethylene oxide to acetaldehyde by the following mechanism.<BR>The colored component seems to be formed by the condensation of acetaldehyde from the fact that crotonaldehyde was detected in it.
