摘要
1. A process for purifying the crude condensation product of aminoalkyl alkanolamines corresponding to the following general formula H2 N-(CH2 )2 -NH-(CH2 )n -OH in which n is the number 2 or 3, and C6 -C22 fatty acids and, if desired, for subsequently alkylating and, optionally, quaternizing the purified condensation product to form amphoteric surfactants having improved stability in storage, characterized in that the crude condensation product of fatty acids and aminoalkyl alkanolamines is subjected to alkaline hydrolysis at temperatures in the range from 70 to 100 degrees C.
