Abstract

본 발명에 따라, 활성 수소 원자를 함유하는 화합물의 알콕실화를, 촉매로서 알킬-또는 알케닐석신산 모노에스테르의 특정 알칼리 토금속 염의 존재하에 수행한다. 수득된 알콕실레이트는 좁은 동족체 분포도와 우수한 외관을 갖는다.According to the invention, alkoxylation of compounds containing active hydrogen atoms is carried out in the presence of certain alkaline earth metal salts of alkyl- or alkenylsuccinic acid monoesters as catalysts. The alkoxylates obtained have a narrow homologue distribution and good appearance.
