Toluenesulfonic acid. Acts as a catalyst. It is a high purity TSA, 65% active in water with low sulfones. It is made by sulfonating aromatic compounds with sulfuric acid, SO3, or oleum. It is designed to replace p-TSA, monohydrate in many industrial catalysis applications. It combines ease of use with the relatively low cost of liquid mixed isomer TSA solutions. It is comparable in strength to mineral acids such as sulfuric acid, but is especially suitable for organic reactions where an inorganic, mineral acid could cause charring, oxidation, or an unwanted chemical reaction.
