英文名称 p-Toluenesulfonic acid monohydrate 生化机理 p-Toluenesulfonic acid monohydrate is an organic-soluble acid catalyst in organic synthesis. The catalyst has been incorporated in the esterification of carboxylic acids or transesterification of esters. The compound has been used as a reducing agent for the reductive amination of ketones and aldehydes. In the presence of p-Toluenesulfonic acid monohydrate novel deazaflavin-cholestane hybrid compounds have been synthesized in a condensation reaction. 2-Phenylethyl alpha-glucoside has also been synthesized in the presence of p-Toluenesulfonic acid monohydrate.

产品介绍 易溶于水、醇和醚，极易潮解，易使棉织物、木材、纸张等碳水化合物脱水而碳化，难溶于苯和***。碱熔时生成对甲酚。本品有时会以含1分子结晶水或4分子结晶水存在。 有机合成、测定伯胺类、染料工业。 p-Toluenesulfonic acid monohydrate, an oxonium salt, is an inexpensive and easy to handle organic catalyst used in organic synthesis. The study of its crystalline structure shows that it is monoclinic with P21/c space group. Its solubility in aqueous sulfuric acid solutions has been studied A catalyst in esterification, reductive amination, and synthesis of bio-compounds. Application： p-Toluenesulfonic acid monohydrate is used as a catalyst in the synthesis of resveratrol, in oxane derivatives as an antimalarial agent, as substituted piperidine and unsymmetrical benzyl. It acts as a catalyst in the preparation of 1,3,5-trisubstituted pyrazoles derivatives, selenated ketene dithioacetals, triazoloquinazolinone and benzimidazoquinazolinone derivatives. It also serves as an intermediate in the esterification and in reductive amination reactions.
