| Study on the Synthesis of Diethyl Phosphite. |
| DENG Ji yong; et al（Department of Chemistry and Chemical Engineering; Hunan Institute of Engineering; Xiangtan 411101） |
| Abstract：The preparation of diethyl phosphite was presented using phosphorus trichloride and ethyl alcohol as materials and trichloromethane as solvent, The influences of mole ratio, time, temperature and the mount of solevent on the reaction were studied, and the optimal technology conditioin was obtained: ethyl alcohol:phosphorus trichloride equals 4∶1;temperature of reaction 6～8℃; time of reaction one hour; amount of solvent 60～80ml. On the optimal condition, the rate of production arrive to 84.5% with purity o... |
