Product Description：

Properties and Usage:

p-Toluenesulfonic acid（CAS 104-15-4）, referred to as PTSA, is a strongly acidic organic sulfonic acid, which appears as colorless crystals or white particles. It has low volatility and efficient catalytic performance.

1. Organic synthesis and catalysts

p-Toluenesulfonic acid serves as an acid catalyst. In the esterification reaction, PTSA can efficiently promote the formation of ester compounds from alcohol and acid, and at the same time absorb the moisture produced by the reaction to promote reaction balance. In alkylation and dehydration reactions, it can effectively promote the combination of alkyl groups and organic molecules, and achieve efficient conversion of alcohols and aldehydes.

2. Polymerization and polymer materials

In the synthesis of polymer materials, p-toluenesulfonic acid is used in the preparation of polyester and polyurethane. Its catalytic performance significantly improves polymerization reaction efficiency and product performance, and is an important additive in the polymer industry.

3. Synthesis of drugs and chemicals

p-Toluenesulfonic acid plays a catalytic and intermediate role in drug synthesis, especially for the sulfonation of aromatic compounds and the preparation of organic sulfur compounds. At the same time, it is an important raw material for the production of many fine chemicals.

4. Industrial cleaning and water treatment

In the process of metal surface treatment and water treatment, p-toluenesulfonic acid is used as a highly efficient cleaning agent, which can remove oxides and dirt on the metal surface. It is also used in the field of water treatment to remove and stabilize metal ions.

5. Synthesis of dyes and pigments

Para-toluenesulfonic acid is used to catalyze the reaction of aromatic compounds and is a key additive in the synthesis of special dyes and pigments, providing efficient chemical solutions for the dye industry.
