Patent abstract
Disclosed is a method for removing aldehyde impurities from a methyl acetate supply. The method comprises reacting the methyl acetate supply with a polyol and converting the aldehyde impurities to cyclic acetals. The acetals are subsequently removed from the methyl acetate supply by, e.g., distillation. The purified methyl acetate supply is used for carbonylation to produce acetic acid.
