研究了1,1,2,3-四氯丙烷的乳液消除反应动力学.此反应是二级反应,主要产物是1,1,3-三氯丙烯-2,并有少量顺式及反式-1,2,3-三氯丙烯.从实验发现一系列独特的界面反应特征:(a)乳液消除反应速度常数-表面活性剂浓度图的实验点符合折线关系,折线交点落在某一临界表面活性剂浓度上;(b)表观活化能随表面活性剂浓度的增高而先呈线性增大,达极大值后又急剧下降,最后趋近极限值;(c)表观速度常数Ktd几乎不随分散相对分散介质体积的分数变化而改变;(d)反应速度常数的对数随水相离子浓度对数的增大而下降.

Kinetics of the elimination reaction of 1, 1, 2, 3-tetrachloropropane had been studied in emulsion system. It was found that the reaction was second order, the major product resulting from the elimination reaction of 1, 1, 2, 3-tetrachloropropane was 1,1,3-trichloropropene-2, the minor products were cis-and traces-1, 2, 3-trichloropro-Igene.
