摘要： A method of methacrylate production includes the steps of providing methacrylate gas mixture; absorbing said gas mixture by water to form a solution mixture; introducing said solution mixture into a distillation column, separating impure methacrylate from said solution mixture in said distillation column that solution of said impure methacrylate is collected at said stripping section of said distillation column; and removing acetic acid from said impure methacrylate to produce methacrylate. It effectively enhances the separation capacity of the distillation column, lowers the whole column pressure drop and operation temperature, avoids the polymerization tendency of the methacrylate under high temperature, to make the water content of the bottom discharging decreases to 0.6%, acetic acid content reduces to below 2%, methyl acrylic content of the top column water phase decreases to 0.5%, thereby reduces the methacrylate products unit consumption and improves the product quality.
