p-Toluenesulfonic Acid is a white and crystalline organic sulfonic acid. In chemical and physical respect sulfonic acids are comparable with sulfuric acid, whereby they have the advantage, that they do not serve the oxidation of organic substances. Sulfonic Acids have physical properties, which are characteristic for diametrically compounds and very simple water solubility.

Examples of applications

p-Toluenesulfonic Acid is used for the production of active pharmaceutical ingredients, fine chemicals, pesticides, resins, hardeners, paints and coatings as well as catalyst for electro conductive polymers. Additionally it is used as catalyst for acetalization of aldehydes, esterification of carboxylic acids, transesterification of esters.
