制备聚醚醇的方法
摘要：
本发明提出一种通过在催化剂存在下，在反应装置(1)中使以下反应物转化以形成液体反应混合物，从而制备聚醚醇的方法：a)一种或多种氧化烯烃和任选的二氧化碳，以及b)一种或多种H官能化的起始物质，其特征在于所述反应装置(1)具有形成多个微结构流道的内部件(2)，其使液体反应混合物多重分割为组分流径并使其在交替排列下重新组合，将多重分割和重新组合重复数次，且其中微结构流道的特征尺寸(将其定义为在液体反应混合物中任何颗粒与离该颗粒最近的流道壁之间的最大可能距离)为20-10000μm，其中由于微结构流道，结果为液体反应混合物的流动剖面接近理想的活塞式流动。
摘要（英）：

What is proposed is a process for preparing polyether alcohols by conversion of the following reactants: a) one or more alkylene oxides and optionally carbon dioxide and b) one or more H-functional starter substances, in the presence of a catalyst, to form a liquid reaction mixture, in a reaction unit (1), which is characterized in that the reaction unit (1) has internals (2) which form a multitude of microstructured flow channels which bring about multiple splitting of the liquid reaction mixture into component flow paths and recombination thereof in altered arrangement, the multiple splitting and recombination being repeated several times and the microstructured flow channels having a characteristic dimension which is defined as the greatest possible distance of any particle in the liquid reaction mixture from the wall of a flow channel closest to the particle, in the range from 20 to 10 000 pm, the result being that the flow profile of the liquid reaction mixture approximates to ideal plug flow as a result of the microstructured flow channels.
