摘要: The invention is related to a method for preparing polyether polyols, wherein the method comprises the steps of: a) providing a crude polyether polyols and a base catalyst; b) mixing the crude polyether polyols mixture with an acid thereby providing a neutralized polyether polyols mixture; c) removing water from the neutralized polyether polyols mixture, thereby providing a dehydrated neutralized polyether polyols mixture comprising polyether polyols and a suspension of the crystallized salts suspended in the polyether polyols; d) separating the polyether polyols from the crystallized salt by filtration resulting in a filtration cake comprising crystallized salts and remaining polyether polyols around the crystals; e) removing polyether polyols from the filter, leaving a filtration cake; f) redissolving the filtration cake obtaining a mixture of a salt solution and the remaining polyether polyols; and separating and removing the remaining polyether polyols from the salt solution.
