25 KG/BAG P Toluenesulfonic Acid PTSA White Powder For Medicine, Agriculture And Detergents Industry
P-toluenesulfonic acid (molecular structure :p-CH3C6H4SO3H, also written TsOH, English P-Toluenesulfonic acid) referred to as PTS, is a non-oxidizing Chemicalbook organic strong acid, white needle or powder crystals, soluble in water, alcohol, and other polar solvents. Easy deliquescence, easy to dehydrate wood and cotton fabric and carbonize, difficult to dissolve in benzene and toluene; P-cresol is formed in alkali melting.
1. Used as a chemical reagent, also used in dyes, organic synthesis.
2. P-toluenesulfonic acid can be used as an intermediate in medicine (such as doxycycline), pesticides (such as dicofol), dyes, etc. Also used in detergents, plastics, coatings and other aspects.
3. It is used in medicine, pesticides, dyes and detergents, as well as in plastics and printing coatings.
4. P-toluenesulfonic acid is widely used in the synthesis of medicine, pesticides, polymerization stabilizers and catalysts for organic synthesis (esters, etc.). It is also used as an intermediate for medicine, coatings and resin curing agent.
