Propionyl chloride CAS 79-03-8 Product Description

propionyl chloride uses

Propionyl chloride is used as an intermediate in the production of agrochemicals and pharmaceuticals. It serves as an intermediate for dyes, textile auxiliaries and peroxide compounds. It acts as a crop protecting agent.

propionyl chloride synthesis

Propionyl chloride is synthesized by reacting propionic acid with phosphorus trichloride at 40-50°C for 1h, cooling, standing, separating and distilling to obtain the product.
CH3CH2COOH+PCl3→CH3CH2COCl+HOPCl2
Propionyl chloride is produced industrially by treatment of propionic acid with phosgene or thionyl chloride. The reaction occurs at ca. 50°C in the liquid phase in the presence of dialkylformamides. The product is then separated by distillation.
CH3CH2CO2H + COCl2 → CH3CH2COCl + HCl + CO2
Propionyl chloride can also be obtained by the reaction of propionic acid with PCl5.

propionyl chloride structure

Propionyl chloride (also propanoyl chloride) is the organic compound with the formula CH3CH2C(O)Cl. It is the acyl chloride derivative of propionic acid. It undergoes the characteristic reactions of acyl chlorides. It is a colorless, corrosive, volatile liquid.
