(EN) PROCESS FOR THE CONTINUOUS PRODUCTION OF POLYOXYALKYLENE POLYOLS
(ZH) 用于连续制备聚氧化烯多元醇的方法
Abrégé
(EN) The invention relates to a process for producing a polyoxyalkylene polyol, comprising depositing an alkylene oxide onto an H-functional starter substance in the presence of a double metal cyanide (DMC) catalyst, wherein the alkylene oxide is dosed at the mass flow rate m(alkylene oxide), the H-functional starter substance is dosed at the mass flow rate m(starter substance), and the double metal cyanide (DMC) catalyst is dosed in a dispersant at the mass flow rate m(DMC) continuously into the reactor with the reaction volume V during the reaction, and the resulting reaction mixture is continuously removed from the reactor, and wherein the quotient of the sum of the mass flow rates [sigma]m of m(alkylene oxide), m(starter substance) and m(DMC) to give the reaction volume V in the steady state is greater than or equal to 1200 g/(h.L).
(ZH) 本发明涉及制备聚氧化烯多元醇的方法,其包括在双金属氰化物(DMC)催化剂存在下将环氧烷加成到H‑官能起始剂物质上,其中环氧烷以质量流量m(环氧烷)、H‑官能起始剂物质以质量流量m(起始剂物质)和在分散介质中的双金属氰化物(DMC)催化剂以质量流量m(DMC)在反应过程中连续计量加入到具有反应体积V的反应器中,并从反应器中连续移除所得反应混合物,并且其中在稳态下由m(环氧烷)、m(起始剂物质)和m(DMC)组成的质量流量总和∑m与反应体积V的商大于或等于1200 g/(h∙L)。
