Transcript of Methyl Acetate
METHYL ACETATE/METHANOL/WATER SYSTEM
Mixtures of methyl acetate, methanol, and water are generated in the production of polyvinyl alcohol. Both the methyl acetate and the methanol must be recovered for recycling or for further processing. It is ternary system that is fairly non-idealVaporLiquid EquilibriumMethyl acetate and methanol form a homogeneous minimum-boiling azeotrope at 1.1 atm with a composition of 66.4 mol% methyl acetate and a temperature of 329 K. This means that the overhead product from a distillation column separating this binary mixture cannot have a methyl acetate composition greater than this azeotropic composition. In addition, methyl acetate and water form a homogeneous minimum-boiling azeotrope at 1.1 atm with a composition of 88.84 mol% methyl acetate and a temperature of 333.8 K.
