Hazard Information

General Description

A pale liquid with a slight odor. Sinks in and mixes with water. Only aluminum, stainless steel or steel covered with a protective lining or coating may contact the liquid or vapor.

Reactivity Profile

2-CHLOROPROPIONIC ACID(598-78-7) is neutralized in exothermic reactions by all bases. Reacts with aqueous solutions containing a chemical base and dissolves if neutralization generates a soluble salt. May react with active metals to form gaseous hydrogen and a metal salt. May corrode or dissolve iron, steel, and aluminum parts and containers. Reacts with cyanide salts to generate gaseous hydrogen cyanide. Reacts with diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides to generate flammable and/or toxic gases and heat. Reacts with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), to generate flammable and/or toxic gases and heat. Reacts with carbonates and bicarbonates to generate a harmless gas (carbon dioxide) but some heat. Can be oxidized by strong oxidizing agents and reduced by strong reducing agents. These reactions generate heat. A wide variety of products is possible. May initiate polymerization reactions or catalyze other chemical reactions. Fire produces highly toxic chloride fumes [USCG, 1999].

Air & Water Reactions

Water soluble.

Hazard

Combustible. Toxic by skin contact. Male reproductive damage.

Health Hazard

Harmful if inhaled. Irritating to throat. May cause severe skin and eye burns. Harmful if absorbed through skin.

Chemical Properties

colourless liquid

Flammability and Explosibility

Nonflammable

Biochem/physiol Actions

2-Chloropropionic acid on oral administration induces necrosis of granule cell layer of rat cerebellum.

Purification Methods

Dry it with P2O5 and fractionally distil it under vacuum. [Beilstein 2 IV 745.]
