Propionyl chloride appears as a colorless liquid with a pungent odor. Corrosive and very irritating to skin and eyes. Used to make other chemicals.
Propionyl chloride is a colorless to light yellow, volatile, and readily flammable liquid, whose vapors hydrolyze in moist air. It is corrosive, lachrymatory, and has a strongly pungent odor. With water and lower alcohols it reacts vigorously under solvolysis to give the acid or ester. It is used for the introduction of the propionyl group and for the synthesis of propionate esters because of its high reactivity.
propionyl chloride Application
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 Uses
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.
Acid halides, such as Propionyl chloride, are water reactive; some are violently reactive. They are incompatible with strong oxidizing agents, alcohols, amines, and alkali. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291].
