Abstract
PURPOSE: To obtain the titled compound advantageously, by separating methacrylic acid and the titled compound by distillation from the esterification product of methacrylic acid with methanol, and eliminating the formed polymer as a by-product dissolved in toluene-methanol mixture solvent, etc.
CONSTITUTION: Methacrylic acid is esterified with methanol to prepare methyl methacrylate which is separated by distillation into methacrylic acid and methyl methacrylate. Methacrylic acid and/or a polymer of methyl methacrylate formed in the above-mentioned reaction as a by-product, is eliminated by dissolving in piridine, dioxane, dimethylformamide, toluene-methanol, mixture solvent or xylene- methanol mixture solvent, especially one at a weight ratio between toluene or xylene and methanol or 2W4.5:8W5.5, to separate methyl methacrylate smoothly by distillation.
