    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: 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.
