Hydrolysis of methyl acetate

In a process for the recovery of methanol and acetic acid from methyl acetate in which methyl acetate is continually hydrolyzed and methanol and acetic acid separated from the resulting mixture of methanol, acetic acid, water and unreacted methyl acetate, the improvement which comprises feeding methyl acetate, water and optionally minor proportions of methanol and acetic acid to a liquid-filled hydrolyzer containing a cation exchange resin in the acid form and maintained at a temperature of about from 50.degree.-90.degree. C., inclusive at a gauge pressure of about from 0 to 240 kPa to produce a mixture of methanol, acetic acid, water, and unreacted methyl acetate, continuously distilling the mixture in a distillation column or flasher, continuously removing an overhead mixture of methyl acetate, water, methanol and, optionally, minor amounts of acetic acid from the top of the distillation column or flasher and returning the overhead mixture directly to the hydrolyzer, and withdrawing from the bottom of the distillation column or flasher a bottom mixture of acetic acid, water, methanol and optionally methyl acetate.
