Chemical Structure
Product Introduction:
P-toluenesulfonic acid (molecular structure: p-CH3C6H4SO3H, also written as TsOH) referred to as PTS, is a non-oxidizing organic strong acid, the acidity is one million times that of benzoic acid.
In general, p-toluenesulfonic acid is a white needle or powder crystal, soluble in water, alcohol, ether and other polar solvents. It is very easy to deliquescence, and it is easy to dehydrate and carbonize wood and cotton fabrics. It is insoluble in benzene and toluene. P-cresol is formed when alkali is melted.
Common in the market is p-toluenesulfonic acid monohydrate (TsOH·H2O) or tetrahydrate (TsOH·4H2O).
Rock Chemical is committed to producing high quality p-toluenesulfonic acid powder. Professional production equipment and first-class management system ensure that the purity of its products meets the standards.
For customers, choosing a chemical manufacturer like Zhishang Chemical to buy raw materials will save even more money! Due to the fact that there is no intermediary to obtain the difference.

Product Packaging
Product Usage:
P-toluenesulfonic acid is widely made use of in the synthesis of medications, pesticides, stabilizers for polymerization, catalysts for organic synthesis (esters, etc), intermediates for layers and resin healing agents.
It is an acid catalyst commonly used in organic synthesis. It can be neutralized with sodium hydroxide to obtain sodium p-toluenesulfonate, and then reacted with phosphorus pentachloride to obtain p-toluenesulfonyl chloride. The latter are used in nucleophilic substitution reactions and also serve as protecting groups for alcoholic hydroxyl groups.
P-toluenesulfonic acid is used as medicine (such as doxycycline), pesticide (such as dicofol), stabilizer for polymerization and catalyst for organic synthesis (esters, etc.).
It can also be used as a chemical reagent, as an intermediate for dyes, etc., and in organic synthesis. Also used in detergents, plastics, coatings, etc.
The use of p-toluenesulfonic acid is also used to catalyze dihydrofuran protecting groups on alcohols, esterification of carboxylic acids, transesterification reactions, and the formation of acetals from aldehydes.
At present, as an important fine chemical product, p-toluenesulfonic acid has been widely used, and the market demand is increasing.
