Abstract

PURPOSE: To remove both hydrocarbons and waste from the top of a rectifying column, by carrying out the rectification of mixed solution of methyl methacrylate containing methanol and methyl isobutyrate in such a way that specific saturated hydrocarbons are made to exist only in parts higher than the feed plate of the mixed solution.
CONSTITUTION: In carrying out the titled purification by rectifying a mixed solution containing methanol, methyl methacrylate, methyl isobutyrate, or, additionally water, 6W8C saturated hydrocarbons are made to exist only in parts higher than the feed plate of the mixed solution and the rectification is done, so that the saturated hydrocarbons, a small amount of methyl methacrylate, and the whole amount of methyl isobutyrate and methanol are distilled from the top of the column, and methyl methacrylate or it and water are recovered from the bottom of the column. The distillate from the top of the column is subjected to layer separation by a layer separating tank into a hydrocarbon layer and a methanol layer. The former is refluxed to the rectifying column, and the latter is distilled. The saturated hydrocarbon and part of methanol are recovered and returned to the two layer separating tank.
