P-toluenesulfonic acid is a commonly used acid catalyst in organic synthesis. It is neutralized with sodium hydroxide to prepare sodium p-toluenesulfonate, and then reacted with phosphorus pentachloride to prepare p-toluenesulfonyl chloride. The latter is used in nucleophilic substitution reactions and also as a protecting group for alcoholic hydroxyl groups.
p-CH3C6H4SO3Na + PCl5 → p-CH3C6H4SO2Cl
Uses synthetic detergent-like solvents, cooking agents and pharmaceutical synthetic intermediates, main and other solvents, dispersants and anticoagulants.
Solubilities of organic substances in aqueous solutions of succinic acid, aqueous concentrations of tunable precipitating solutions, uniform mixtures of various heterogeneous substances formed by their action, low crystallinity and liquidity.
1. The electronics industry is used to coat cathodes, agriculturally used as quick-acting fertilizers for acid soils, and quick calcium supplements for plants.
2. Used as analytical reagents and firework materials.
Calcium dihydrogen phosphate is an important ingredient in phosphate fertilizers such as superphosphate. It is also used as a food additive.
Can also be used as animal feed additives.
