A method for preparing dimethyl phosphite was developed from methanol and phosphorous trichloride.
研究了用三氯化磷和甲醇合成亚磷酸二甲酯的方法。
The result shows in the new process phosphorous trichloride consumption can be reduced and phosphorous acid recovery can be increased by about 10%.
结果表明，该工艺改造使三氯化磷消耗降低，亚磷酸得率提高约10%。
