For Nitro derivatives of methylbenzenes, the pyrolysis initial reaction is an isomerization reaction. It means the alpha C-H bond in methyl rupture, then the Hydrogen atom transfer to the Oxygen atom in nitryl to form isomer.

甲苯的硝基衍生物的热解引发反应为异构化反应——α_中的C-H键断裂，氢原子转移到邻位硝基(-NO_2)中的氧原子上，生成新的异构体化合物。

Nitro derivatives of phenols, the pyrolysis initial reaction is an isomerization reaction It meansthe O-H bond in hydroxide rupture, then the Hydrogen atom transfer to the Oxygen atom in nitryl to form isomer.

苯酚的硝基衍生物的热解引发反应为异构化反应——酚羟基中的氢氧键断裂，氢原子迁移到邻位硝基(-NO_2)中的氧原子上，形成新的异构体化合物。

One end group is onium ion which has the capability of exchanging cations between layers of MMT, another is one of the groups which can react with copolyesters. MMT treated by such intercalants is dispersed in copolyesters at nano scale easily.

效果良好的插层剂分子末端应带有两个活性基团：一端带正电荷能交换MMT层间的阳离子，另一端带有反应性官能团可以与基体反应。

The calcination of the catalysts at high temperature may easily result in theformation of tetrahedral structure Mo species before sulfidation,and decrease theamount of octahedral coordination Mo species.The sinter and loss of the activecomponents would take place during the calcination at overhigh temperature. Meanwhile,the active component could react with support,thus made the activecomponents entered into support bulk phase.

7催化剂在硫化前进行高温焙烧，容易形成四面体结构的钼物种，而八面体配位钼物种减少，且过高的焙烧温度易使活性组分发生烧结，同时可能发生活性组分的流失或与载体发生反应进入载体体相。
