Abstract
Acetone produced as a by-product in the reaction of methyl acetate with carbon monoxide and hydrogen in the presence of a Group VIII noble metal catalyst and methyl iodide is recovered from the reaction mixture by supplying acetone to provide an acetone to methyl iodide molar ratio of at least 1:10 and distilling the mixture comprising methyl iodide, acetone and methyl acetate to separate substantially all of the methyl iodide and the supplied acetone and some of the methyl acetate from the remaining acetone and methyl acetate and thereafter separating the acetone from the methyl acetate.
