4-甲酰苯磺酸的合成研究

Study on synthesis of 4-formylbenzene sulfonic acid

4-甲基 -苯磺酸经光溴化、酸性水解 ,然后用双氧水氧化得到 4-甲酰苯磺酸 ,三步总收率为 47.9%。

The synthesis of 4\|formylbenzene sulfonic acid was studied in this article, In the synthesis of the 4\|formlbenzene sulfonic acid, 4\|methyl\|benzene\|sulfonicacid was light brominated by bromine without solvent and then acidic hydrolysised, then oxided by H\-2O\-2;The total yield is about 47.9%; This process is a efficient method for the synthesis of 4\|formlbenzene sulfonic acid.
