1·It is very important to determine the protonation constants of tetraphenylporphyrin derivatives for studying their colorful performance.
卟啉类试剂质子化常数的测定对于研究其显色性能有着重要的意义。
2·The result shows that both the protonation of the ligands and the formation of metal complexes are controlled by the change of enthalpy.
其结果显示了配体的质子化和金属配合物的形成受到焓变化的控制。
3·According to the mechanism, olefin protonation is a process of acid-alkali reaction, so the reaction is easy to happen when the acidity of catalyst and the basicity of olefin are very strong.
按此机理，烯烃的质子化是酸碱反应过程。因此，催化剂的酸性和烯烃的碱性均较强时对反应是有利的。
