The chain initiation was accomplished by-OH, the pyrolysis can also produce some radicals of high activity. 链引发主要由·OH完成,其它如热解等也可产生活性极强的自由基。
Study on the chain initiation of catalytic cracking reaction in MIP PROCESS MIP技术反应过程中裂化反应链引发的机理研究
In chain initiation reaction, the inhibitor primarily effects the length of the induction period and the level of difficulty to react. The specific performance are the thermal stability and reaction kinetics of the system. 对于链引发反应,阻聚剂主要影响的是链引发反应的诱导期长短和引发反应进行的难易程度,具体表现在体系的热稳定性和反应动力学上。
In the chain initiation, because of containing unsaturated bonds in all the reactants, their activity are higher and often reacted by light, heat and other factors. 在聚合反应的链引发反应中,由于反应物中都含有不饱和键,所以其活性较高,往往因光、热等因素的作用而引发聚合。
Theoretical calculations have been used to investigate the thermal CO2 reforming of CH4, It is found that the first step is the CH4 dissociation into CH3 and H radicals for the chain initiation reaction. 在CO2热重整CH4反应机理的研究中发现反应的链起始(CI)步骤是CH4解离生成CH3和H自由基。
