查询词典 hydrogenolysis

And the optimum pH was 4-6 for the dechlorination reaction of 2,4-D, and pH between 2 and 8 were all suited for the reaction in Pd/Fe systems. Intermediate and final products of 2,4-D, HCH and chlordane with Pd/Fe were determined by GC/MS, and the possible dechlorination pathways were concluded: 2,4-D can be converted to phenoxyacetic acid through gradual hydrogenolysis, and HCH can be transformed to cyclohexatriene through dichloroelimination or dehydrochlorination.

通过GC/MS定性定量分析了三种目标污染物在Pd/Fe体系中发生还原脱氯反应过程中的反应物及最终产物，并根据反应产物推测分析了这三种有机污染物在催化还原反应体系中可能的反应途径：2，4-D主要通过逐级氢解最终生成彻底脱氯产物苯氧乙酸；而六六六则可能通过逐步双氯消除反应或脱氯化氢反应，最后生成环己三烯。

The possible dechlorination or hydrogenolysis is excluded from the system by both experimental data and the theory analysis.

另外，当催化剂中Ti的含量在0.25—1.0％时，上述各种参数随Ti量而变化的幅度不大，这可能是因为催化剂中未被还原的Ti~(4+)具有增强Pt的活性的作用，因此它部分抵消了Ti~或Ti~0所起的减弱Pt的活性的作用。
