Crystalline Powder P Toluenesulfonic Acid,
Organic Intermediate P Toluenesulfonic Acid
PTSA P-Toluene Sulfonic Acid P-Toluenesulfonic Acid For Organic Intermediate
P-Toluenesulfonic Acid is a white acicular crystal or crystalline powder is a kind of strong organic acid (acid). Compared with some inorganic acid is not oxidized, can replace inorganic acid in some cases. The uniqueness of P-Toluenesulfonic Acid is that it is usually the case for a solid, easy to use. It is white needle-like or powder crystal, easily deliquescent, soluble in water, alcohol and other polar solvents. Will dehydrate and carbonize paper, wood, etc.

1. Used as a slurry conditioner in the chemical industry and synthetic detergents; used as a water-assisted solvent for synthetic detergents, mixed into powder detergents to increase water content, and at the same time improve fluidity, feel, anti-caking properties, etc. Both have good results. It is also used as a crystallization additive in fertilizer production.
2. In liquid detergents, it is mainly used as a solubilizer. After adding sodium p-toluenesulfonate, the viscosity and cloud point will decrease. When using, pay attention to the content of raw materials, inorganic salts and solubility. Especially for liquid detergents, the salt content has a great influence on the transparency of the liquid.
3. Used in the organic synthesis industry, in medicine for the synthesis of doxycycline, persentine, naproxen and the production of amoxicillin and cefadroxil intermediates.
