Description:
PTS, is a non-oxidizing organic strong acid, white needle or powder crystal, soluble in water, alcohol , Ethers and other polar solvents. Easy deliquescence, easy to make wood, cotton fabric dehydration and carbonization, insoluble in benzene and toluene. Alkali fusion generated when p-cresol. Commonly, p-toluenesulfonic acid monohydrate (TsOHH2O) or tetrahydrate (TsOH4H2O) is preferred.

Chemical properties: colorless monoclinic sheet or columnar crystals. Soluble in ethanol and ether, slightly soluble in water and hot benzene.

Usage:
1. For chemical reagents, but also for dyes, organic synthesis
2. Used as medicine (such as doxycycline), pesticides (such as dicofol), dyes and other intermediates. Also used in detergents, plastics, coatings and so on.
3. For medicine, pesticides, dyes and detergents, but also for plastics and printing coatings
4. Widely used in the synthesis of pharmaceuticals, pesticides, polymerization of the stabilizer and organic synthesis (esters, etc.) catalyst. Also used as medicine, paint intermediates and resin curing agent.

Brief manufacture process:
By p-toluenesulfonyl chloride hydrolysis derived. Toluene can also be used as raw materials, sulfonated by sulfuric acid derived.
