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.

一般描述

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,难溶于苯和甲苯。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。


A catalyst in esterification, reductive amination, and synthesis of bio-compounds.
