Abstract
The present invention relates to new crystalline molecular sieve SSZ-75 having STI topology prepared using a tetramethylene-1,4-bis-(N-methylpyrrolidinium) dication as a structure-directing agent, and its use in catalysts for making amines.
Claims6
A process for producing methylamine or dimethylamine comprising reacting methanol, dimethyl ether or a mixture thereof and ammonia in the gaseous phase in the presence of a catalyst comprising a crystalline molecular sieve having STI topology and having a mole ratio of at least 15 of (1) an oxide of a first tetravalent element to (2) an oxide of a trivalent element, pentavalent element, second tetravalent element which is different from said first tetravalent element or mixture thereof.
