Abstract
Catalytic dehydration-hydrolysis process for the co-production of acetic acid and dimethyl ether from a mixture of methanol and methyl acetate and water in which the amount of water fed to the process is controlled by the steps of dehydrating a methanol feed to provide a crude product containing dimethyl ether, unconverted methanol and water, recovering therefrom a stream containing dimethyl ether, water and methanol and a water stream and separating dimethyl ether from the dimethyl-ether containing stream to produce a methanol stream containing methanol and water. At least part of the methanol stream and methyl acetate is supplied to the dehydration-hydrolysis process.
