Process for dehydrating methanol to dimethyl ether |
| abstract |
A process for dehydrating methanol to dimethyl ether product in the presence of an aluminosilicate zeolite catalyst and a promoter selected from (i) aldehyde of formula R 1 CHO (Formula I) in which R 1 is hydrogen, a C 1 -C 11 alkyl group or a C 3 -C 11 alkyl group in which 3 or more carbon atoms are joined to form a ring; or (ii) acetal derivative of an aldehyde of Formula I; and the molar ratio of promoter to methanol is maintained at 0.1 or less. |
