Acryloyl chloride, also known as 2-propenoyl chloride, acrylyl chloride, or acrylic acid chloride, is the organic compound with the formula CH2=CHCO(Cl). It is a colorless liquid, although aged samples appear yellow. It belongs to the acid chlorides group of compounds.[1]

Preparation

[edit]

Acryloyl chloride can be efficiently prepared by treating acrylic acid with benzoyl chloride:[2]

CH2=CHCO2H + C6H5COCl → CH2=CHCOCl + C6H5CO2H

Conventional phosphorus-based chlorinating agents, e.g. phosphorus trichloride, are ineffective. Flow conditions allows use of a broadened range of chlorinating agents including oxalyl chloride and thionyl chloride.[1] [3]

Reactions

[edit]

This compound undergoes the reactions common for acid chlorides. For example, it reacts readily with water, producing acrylic acid. When treated with sodium salts of carboxylic acids, the anhydride is formed. Reactions with alcohols and amines gives esters and amides, respectively. It acylates organozinc compounds.[4]

Acryloyl chloride is most commonly employed for the introduction of acrylic groups into other compounds, e.g. the preparation of acrylate monomers and polymers.[5]

Toxicity

[edit]

Acryloyl chloride, like volatile acid chlorides, is a skin irritant, with pulmonary edema in more severe exposures.[6] Other signs and symptoms of acute exposure may include headache, dizziness, and weakness. Gastrointestinal effects may include nausea, vomiting, diarrhea, and stomach ulceration.[7]
