ALKOXYLATION CATALYST, PROCESS FOR THE PREPARATION OF THE CATALYST AND PROCESS FOR PREPARING ALKOXYLATE WITH THE USE OF THE CATALYST |
摘要 |
An alkoxylation catalyst comprising metal oxides, having a basicity point expressed in pKa value from 9 to 25 and an acidity point expressed in the amount of ammonia gas adsorbed from 50 to 500 mu mol/g, and a process for preparing an alkoxylate with the use of this catalyst. According to the present invention, an alkoxylate having a distribution of the number of moles of alkylene oxide added within a narrow range can be prepared and the reaction product is little contaminated with unreacted starting material and by-products. Further, the catalyst can easily be eliminated from the reaction product.
