摘要
通过实验证实杂多酸对甲苯磺化合成4,4’-二甲二苯砜反应具有较好的催化活性,利用紫外光谱研究了杂多酸与对甲苯磺酸的作用。
It is proved by the experiment that HPA is a good catalyst for the reaction of toluene sulfonation to 4,4'-dimethyldiphenyl sulfone. The effect of HPA on p-methyl sulfonic acid has been studied by means of UV and variable-temperature 1H NMR. The preliminary catalytic mechnism is also proposed.
