Applications
Used in paints, paper chemicals, API, detergent, cosmetics. Anionic surfactants (clear liquid detergent, luxury shampoo).
 
Description
p-Toluenesulfonic acid (PTSA or pTsOH) or tosylic acid (TsOH) is an organic compound with the formula CH3C6H4SO3H. It is a white extremely hygroscopic solid that is soluble in water, alcohols, and other polar organic solvents. The CH3C6H4SO2 group is known as the tosyl group and is often abbreviated as Ts or Tos.
 
Preparation
TsOH is prepared on an industrial scale by the sulfonation of toluene. Common impurities include benzenesulfonic acid and sulfuric acid. TsOH monohydrate contains an amount of water. To estimate the total moisture present as impurity, the Karl Fischer method is used.
 
Chemical Properties
Para Toluene Sulfonic Acid (PTSA) is characterized by its strong acidity and high solubility in polar solvents, making it a valuable catalyst and reagent in various chemical processes.
 
Definition
