Abstract
The transesterification process of dimethyl and diethyl phosphite with 1,3-dichloropropanol-2 is examined. It is found that the reaction proceeds in the absence of catalyst at a temperature of 155°, whereas in the presence of morpholine as a catalyst it takes place at 126°C. The transesterification of dimethyl phosphite and diethyl phosphite with 1,3-dichloropropanol-2 is accompanied by the evolution of dimethyl and diethyl ethers and alkyl halides (methyl chloride and ethyl chloride).
