| titleOfInvention | Catalyst for preparing methyl acetate by carbonylating dimethyl ether and its production and use |
| abstract | The present invention provides a kind of catalyst for preparing methyl acetate by carbonylating dimethyl ether and its production and use.More specifically, the present invention provides a kind of catalyst for preparing methyl acetate by carbonylating dimethyl ether, it is characterised in that the catalyst contains the h-mordenite molecular sieve through silicon tetrachloride steam dealuminzation, its sial atomic ratio=3：1~20：1.By the present invention in that being contacted with modenite with silicon tetrachloride steam, with the acidic site effect in twelve-ring duct therein without the acidic site in influence octatomic ring duct, aluminium in selectively removing twelve-ring duct and retain the acidic site in octatomic ring duct, so as to improve life-span and selectivity of the catalyst in preparing methyl acetate by carbonylating dimethyl ether reaction, and then improve the yield of reaction. |
