P Toluenesulfonic Acid Cas 104-15-4

P-toluenesulfonic acid (molecular structure: p-CH3C6H4SO3H, also written as TsOH, abbreviated as PTS) is a non oxidizing organic strong acid, which is a white needle shaped or powdery crystal that is soluble in water, alcohols, ethers, and other polar solvents. Highly deliquescent, easily dehydrates and carbonizes wood and cotton fabrics, and is insoluble in benzene and toluene; During alkali melting, p-cresol is generated.
