氯乙烯高沸废液光氯化制取1,1—二氯乙烷试剂的研究(Ⅰ)

Novel Route of 1, 1-EDC Manufacture from VCM Waste Liquor (Part Ⅰ)

提出了一种利用电石乙炔法生产氯乙烯单体副产的氯乙烯高沸废液制取1,1—二氯乙烷试剂的方法。该方法工艺流程较简单,单位重量产品的经济效益高。另外,从理论上研究了光氯化过程反应机理和反应动力学问题,提出了光氯化反应动力学方程式。

A new route of manufacturing 1, 1-EDC(Dichloroethane) reagent from VCM (by acetylene hydrochlorination) waste liquor is introduced. The lab scale production of 1, 1-EDC shows that economically this technique is attractive due to the low cost and high profit.The kinetic study of the photochlorination reaction used as a seperation method has also been carried out. And the relevant kinetic equation is given .
