COMPOSITE METAL CYANIDE COMPLEX CATALYST, PROCESS FOR PRODUCING THE SAME, AND USE OF THE SAME |
摘要 |
Provided is a double metal cyanide complex catalyst with a high activity which is readily produced on an industrial scale. The double metal cyanide complex catalyst is of a fine particle form and contains t-butyl alcohol or, t-butyl alcohol and another organic compound as an organic ligand. The catalyst of the fine particle form has a volume-average particle size in a range of from 3 to 20 µm, based on measurement by a light scattering method for measuring fine particles having particle sizes of at least 0.15 µm. A particle content of the catalyst in a particle size range of at least 0.15 µm and at most 1 µm is less than 5% by volume, and a particle content of the catalyst over a particles size of 1 µm is in a range of more than 95% and at most 100% by volume. |
