Chloroacetyl chloride Chemical Properties,Uses,Production
Chemical Properties
Chloroacetyl chloride is a colorless to yellowish liquid with a very pungent, extremely irritating, odor.
Uses
Chloroacetyl chloride is an intermediate in the production of alachlor and butachlor. It is used to prepare phenacyl chloride through Friedel-Crafts acylation of benzene.
Application
Chloroacetyl chloride can be used for chloroacetylation and chemical modification of poly(glycidyl methacrylate).
Chloroacetyl chloride was used to study the in vitro metabolism of chloroacetamide herbicides by rat and human liver microsomes. Chloroacetyl chloride was used in the synthesis of some novel quinoline derivatives having antileishmanial activity.
Preparation
Chloroacetyl chloride is usually manufactured from chloroacetic acid by reaction with phosphorus trichloride, thionyl chloride, sulfuryl chloride, or phosgene. It is also obtained by chlorination of acetyl chloride in the presence of stronger aliphatic acids, preferably chloroacetic acids, or from sodium chloroacetate and the usual chlorinating agents.

Definition
Chloroacetyl chloride is classified as an acyl halide. It is a colorless to light yellow liquid with a strong, pungent odor. This compound is highly toxic when inhaled and can corrode both metal surfaces and tissues.
General Description
A colorless to light yellow liquid with a very pungent odor. Very toxic by inhalation. Corrosive to metals and tissue.
Reactivity Profile
Chloroacetyl chloride reacts rapidly with water. Incompatible with strong oxidizing agents, alcohols, bases (including amines). 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].
Hazard
Irritant to eyes, corrosive to skin. Upper respiratory tract irritant.
Health Hazard
Inhalation causes severe irritation of upper respiratory system. External contact causes severe irritation of eyes and skin. Ingestion causes severe irritation of mouth and stomach.
Safety Profile
Poison by ingestion and intravenous routes. Mildly toxic by inhalation. Corrosive. A lachrymator. When heated to decomposition it emits toxic fumes of Cl-.
Potential Exposure
Highly toxic by inhalation. Chloroacetyl chloride is used in the manufacture of acetophenone. It is used in the manufacture of a number of pesticides including: alachlor, allidochlor, butachlor, dimethachlor, formothion, mecarbam, metolachlor, propachlor. It is also used in the manufacture of pharmaceuticals, such as chlordiazepoxide hydrochloride, diazepam, lidocaine, mianserin.
Carcinogenicity
Chloroacetyl chloride was not genotoxic in a number of assays.
Shipping
UN1752 Chloroacetyl chloride, Hazard class: 6.1; Labels: 6.1-Poison Inhalation Hazard, 8-Corrosive material, Inhalation Hazard Zone B.
Incompatibilities
Reacts violently with water, steamforming chloroacetic acid and hydrogen chloride gas. Reacts with alcohols, powdered metals; sodium amide; combustibles; and many organics, causing toxic fumes, fire, and explosion hazard. On contact with air it emits corrosive gas. Decomposes when heated forming phosgene gas. Corrosive to metals.
Waste Disposal
It may be discharged into sodium bicarbonate solution, then flushed to the sewer with water.
