双金属氰化物催化剂的研究进展

综述了近年来双金属氰化物（DMC）催化剂的研究进展，指出DMC催化剂是一类用于环氧化物的高效催化剂，与传统的环氧化物催化剂相比，其制得的聚醚多元醇具有分子量高、不饱和度低、分子量分布窄、平均官能度高等优点。但该催化剂在应用过程中仍存在一些缺点。针对这些缺点，国内外的高校、企业已进行了大量的改性研究工作。

The research progress in bimetal cyanide catalysts

This paper reviewed the recent years' developments of the bimetal cyanide catalysts, a kind of high efficiency catalyst used for epoxide polymerization. The polyether polyols prepared with the bimetal cyanide catalyst possess the advantages of high molecular weight, low degree of unsaturation, narrow molecular weight distribution and high average functionality. However, on the other hand, the catalyst also suffers certain deficiencies in its application process. A lot of research works are done by some universities and enterprises worldwide against the shortcomings of the catalyst.
