Abstract
Process for the co-production of acetic acid and dimethyl ether by contacting methyl acetate and methanol in the presence of a catalyst containing a crystalline zeolite having a FER framework type. The zeolite has crystallites having a dimension of about 500 nm or less in the c-axis.
Claims13
A process for the co-production of acetic acid and dimethyl ether comprising the step of contacting methyl acetate and methanol in the presence of a catalyst comprising a crystalline zeolite having a FER framework type wherein said zeolite has crystallites having a dimension of about 500 nm or less in the c-axis, the ratio of the dimension in the c-axis to the dimension in the b-axis is less than or equal to 3:1 and 1 mol % to 60 mol % of its cation-exchange capacity is occupied by cations of an alkali metal, said alkali metal being cesium.
