Gold-containing catalyst and method of manufacturing epoxide using the same

摘要

An epoxide-manufacturing catalyst is composed of a carrier containing a titanium-carrying silica carrier which is made of a silica carrier carrying a titanium compound and fine gold particles fixed to the same, arranged in such a manner that: (a) an average pore diameter of the silica carrier is in a range between 5 nm and 100 nm; and/or (b) a relation, A/B<0.3, is established, where A is a quantity (mol/g) of titanium metal carried by the titanium-carrying silica carrier per unit weight, and B is a quantity (mol/g) of silanol hydroxyl groups in the silica carrier per unit weight.
