Sodium p-toluenesulfonate Application
1. Can be used in organic synthesis and pharmaceuticals. Slurry conditioning agent for chemical industry and synthetic detergents. It is used as a water co-solvent for synthetic detergents. It can increase the water content when mixed into powder detergents, and it has good effects on fluidity, feel and anti-caking properties. It is also used as a crystalline 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, attention should be paid to the content of raw materials, inorganic salts and solubility. Especially for liquid detergents, the salt content has a great influence on the liquid transparency.
