COMPOSITE METAL CYANIDE COMPLEX CATALYST, PROCESS FOR PRODUCING THE SAME, AND USE OF THE SAME

摘要

A composite metal cyanide complex catalyst which can be industrially produced with ease and is highly active. It is a finely particulate, composite metal cyanide complex catalyst which contains, as an organic ligand, either t-butyl alcohol or a combination of t-butyl alcohol with other organic compound. When analyzed by the light scattering method for examining fine particles having a particle diameter of 0.15 mum or larger, the finely particulate catalyst has a volume-average particle diameter of 3 to 20 mum. Furthermore, the content of catalyst particles having a particle diameter of 0.15 to 1 mum therein is less than 5 vol.% and the content of catalyst particles having a particle diameter exceeding 1 mum therein is 95 to 100 vol.%, excluding 95 vol.%.
