P-Toluenesulfonic Acid/PTS ACID CAS 104-15-4 P-Toluene Sulfonic Acid PTSA
p-toluene sulfonic acid(p-toluene sulfonic acid), is a non-oxidizing organic acid, white needle or powder crystals, soluble in water, alcohols, ethers and other polar solvents. Easy deliquescence, easy to make wood, cotton fabric dehydration and carbonization, insoluble in benzene and toluene. generating p-cresol when alkali fusion. The common ones are p-toluenesulfonic acid monohydrate (TsOH·H2O) or tetrahydrate (TsOH·4H2O).

P-toluenesulfonic acid is a strong organic acid with no oxidizing properties, and its acidity is one million times that of benzoic acid. White needle-like or powder crystals, easily deliquescent, soluble in water, alcohol and other polar solvents. It is made by toluene and chlorosulfonic acid under low temperature. P-toluenesulfonic acid is widely used in the synthesis of pharmaceuticals, pesticides, polymerization stabilizers and organic synthesis (esters, etc.) catalysts. Used as an intermediate for medicines and coatings and as a resin curing agent, as well as an intermediate for electroplating.
