Abstract

A process for the production of a modified H-mordenite which comprises bringing an alkali metal or alkaline earth metal-type mordenite into contact with SiCl₄ under a heating condition and then converting the treated mordenite into an H-type via ion exchange, a catalyst comprising the modified H-mordenite and a process for the production of methylamines using the use of the catalyst.

Claims

1. A process for the production of a modified H-mordenite which comprises

bringing an alkali metal mordanite or an or alkaline earth metal mordenite into contact with SiCl₄ under a heating condition and then

converting the treated mordenite into an H-type via ion exchange.

2. A catalyst comprising a modified H-mordenite obtained by a process as claimed in claim 1.

3. A catalyst for the synthesis of methylamines which comprises a modified H-mordenite obtained by a process as claimed in claim 1.
