摘要:
The invention relates to a process for the preparation of an epoxidation catalyst which process involves: (a) drying a silica gel carrier at a temperature of from 400° C. to 1000° C.; (b) hydrolysing the dried silica gel carrier; (c) optionally drying the hydrolyzed carrier; and (d) contacting the carrier obtained with a gas stream containing titanium halide to obtain an impregnated carrier, in which process the hydrolysis of step (b) is carried out at a temperature of at most 200° C.
