Reaction Conditions

Reaction Steps

A flask filled with nitrogen and fitted with a cooling trap is charged with 216 g of dimethyl methanephosphonate; the contents are heated to 60° C. and a mixture of 200 g of ethyl acrylate and 100 g of methanol is added dropwise in the course of 1 hour, the temperature rising to 65° C. The reaction mixture is further stirred for 1 hour, during which period a total of 91 g of dimethyl ether are collected in the cooling trap. Excess methanol is removed by vacuum distillation. The crude product is obtained in a yield of 362 g with a 97.3% purity, which corresponds to a theoretical yield of 97.9%. The boiling point of a sample is 100°-102° C. at 0.013 mbar.
