Abstract
PURPOSE: To separate methyl methacrylate (MAM) efficiently and economically, by separating methacrylic acid through the distillation of a mixed solution containing water, CH3OH, methacrylic acid and a specific amount of MAM , and subsequently distilling the distillate by use of water as an extractant in the second distillation column.
