Abstract

본 발명은 알카리금속화합물 촉매의 존재하에서 알킬렌옥시드를 중합하여 얻어지는 조제폴리옥시알킬렌폴리올에서 알카리금속화합물 촉매를 회수하는 방법 및 회수된 알카리 금속화합물 촉매를 사용한 폴리옥시알킬렌폴리올의 제조방법을 제공한다.
알카리금속화합물 촉매를 함유하는 조제폴리옥시알킬렌폴리올을 중화함으로써 얻어지는 알칼리금속염을 함유하는 수용액과 음이온교환수지의 접촉에 의해 무기산 또는 유기산 음이온을 흡착시켜 알카리금속화합물 촉매를 회수하고, 회수된 알카리금속화합물 촉매를 사용하여 활성수소화합물에 알킬렌옥시드를 개환부가 중합시켜 폴리옥시알킬렌폴리올을 제조한다. 촉매로서 금속세슘, 수산화세슘 또는 그의 1수화물 혹은 금속루비듐, 수산화루비듐 또는 그의 1수화물이 바람직하다.
