Abstract
Crystalline zeolites having a FER framework type wherein the crystallites have a dimension in the c-axis of about 500 nanometers (nm) or less, a method for their preparation and 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 catalysts comprising the crystalline zeolites.
Claims20
A crystalline zeolite having a FER framework type wherein the crystallites of the zeolite have a dimension in the c-axis of about 500 nanometers (nm) or less, a ratio of the dimension in the c-axis to the dimension in the b-axis being less than or equal to 3:1;
- and wherein 1 mol % to 60 mol % of the cation exchange capacity of the crystalline zeolite is occupied by cations of an alkali metal, said alkali metal being cesium.
