3-Chloropropionic acid Chemical Properties,Usage,Production

Chemical Properties

white to beige crystalline low melting mass

Uses

3-Chloropropionic acid was used to study the degradation of 3-chloropropionic acid by Pseudomonas sp. strain isolated from rice paddy fields. It was also used in determination of 3-bromopropionic acid, biomarker for the exposure to 1-bromopropane in human urine by gas chromatography

General Description

A white crystalline solid with a sharp odor. Denser than water.

Air & Water Reactions

Water soluble.

Reactivity Profile

2-CHLOROPROPIONIC ACID reacts exothermically with bases. Reacts with aqueous solutions containing a 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. Fires produces highly toxic chloride fumes [USCG, 1999].

Health Hazard

Contact may cause skin and eye burns. Harmful if swallowed.

Purification Methods
