Method for producing catalyst for use in production of methylamine compound, and method for producing methylamine compound

摘要

According to the present invention, a method for producing a catalyst for use in the production of a methylamine compound can be provided, wherein the catalyst comprises a modified crystalline silicoaluminophosphate salt molecular sieve. The method comprises: a moisture control step of adsorbing moisture onto a crystalline silicoaluminophosphate salt molecular sieve in an amount of 5 to 30 wt % of the crystalline silicoaluminophosphate salt molecular sieve; and a step of heating the crystalline silicoaluminophosphate salt molecular sieve having moisture adsorbed thereon under a pressure of 0.1 MPa or more and at a temperature of 130 to 350° C. for 5 to 40 hours.
