双金属氰化物络合催化合成聚醚起始条件的研究

Study on Starting Condition for the Synthesis of Polyether Catalyzed by DMC

对双金属络合催化剂用于催化合成聚醚的起始条件进行了研究,讨论了起始温度、催化剂用量、PO的起始压力等因素对聚醚质量的影响。结果表明,起始温度在130℃左右、催化剂质量分数为30×10^(-6)、PO起始压力较低时,得到的聚醚物性较好。

The starting conditions for synthesis of polyether polyols catalyzed by DMC were studied. The effect of starting conditions included starting temperature, amount of DMC and starting pressure of PO on the quality of polyether polyol was discussed. The results show that a polyether polyol with good physical properties is obtained when starting temperature is about 130℃, mass fraction of catalyst DMC is 30 × 10-6 and starting pressure of PO is low.
