propionyl chloride uses

Propionyl chloride is used for the introduction of the propionyl group and for the synthesis of propionate esters because of its high reactivity. It is an chemical intermediate in the preparation of various propionic acid derivatives, It can also be used:
To convert anisole to 4-methoxypropiophenone and 2-methoxynaphthalene to 1-propio-2-methoxynaphthalene in the presence of Indium(III) chloride (InCl3) impregnated mesoporous Si-MCM-41 catalyst.
For chlorination in the presence of sulfuryl chloride and peroxides to form α-chloropropionyl chloride and β-chloropropionyl chloride.
In reaction with (hydroxypropyl)cellulose to form the propanoate ester, [(propionyloxy)propyl]cellulose.

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.
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.
