PROCEDURE

实验过程

To the same apparatus as described in Example 1 were added 2,150 g (25 mol) of methyl acrylate, 370 g (5 mol) of glycide, 1 g of phenothiazine as the polymerization inhibitor and 41.3 g (0.068 mol) of calcium stearate as the catalyst. The resulting mixture was heated at a temperature of 50° to 70° C. under a reduced pressure of 200 to 400 mmHg while introducing a slight amount of air to effect the reaction while distilling off the formed methanol as an azeotropic mixture with methyl acrylate. The reaction was completed in 2 hours. The formation of glycidyl acrylate was 96.5%. 575 g of glycidyl acrylate was obtained by the distillation (purity: 98.1%, yield: 89.7%).
