Abstract: The present invention relates to a process for preparing polyether polyols by base-catalyzed addition of alkylene oxides (epoxides) onto starter compounds which are solid at room temperature and have Zerevitinov-active hydrogen atoms, a particular feature of which is that visually clear and/or homogeneous products are obtained even in the absence of solvents.
Abstract translation: 本发明涉及一种制备聚醚多元醇的方法,该方法是通过在环氧化物(环氧化物)上加成在室温下为固体的起始化合物进行碱催化加成,并具有齐维伏诺 - 活性氢原子,其特征在于目视清楚和/ 或即使在没有溶剂的情况下也可获得均匀的产物。

Abstract: This invention relates to a process for preparing polyols which contain oxyalkylene units. This process comprises neutralizing a crude polyol by addition of an acid, optionally removing water, and removing the salts formed by neutralization. The crude polyol is contacted with the acid for at least 5 minutes.
