proton range

Specific innovative results are as follows: 1. On the basis of inductive analysis of the reported reaction mechanism and kinetics of the esterification stage, the rate constants for the proton acid and Sb3+ catalytic system are drawn under a reasonable range.

具体创新性结果如下1、归纳分析文献报道的酯化阶段反应机理和动力学，对动力学常数进行分析得出适用于质子酸和Sb3+催化体系下反应速率常数的合理范围。

And in a certain range, an increase of pH in solution led to a negative shift in potential for both reduction and oxidation peaks, which indicated that the transfer of electron was accompanied by the transfer of proton.

该氧化还原反应在一定的范围内，氧化还原电对随着溶液的pH的增大而产生负移表明，该电子转移的过程中伴随着质子转移。
