2-Chlorobenzoic acid Usage And Synthesis

Chemical Properties	white crystals or powder

Uses	The toxicity of halogenated benzoic acids was found to be directly related to the compound's hydrophobicity. Toxicity and quantitative structure-activity relationships of benzoic acids to Pseudokirchn eriella subcapitata.

Definition	ChEBI: A monochlorobenzoic acid having the chloro group at the 2-position.

Uses	Preservative for glues, paints. Intermediate in the manufacture of fungicides and dyes.

General Description	Crystals or fine fluffy white powder.

Air & Water Reactions	Insoluble in water.

Reactivity Profile	2-Chlorobenzoic acid is incompatible with strong oxidizing agents and strong bases.

Fire Hazard	Flash point data for 2-Chlorobenzoic acid are not available; however, 2-Chlorobenzoic acid is probably combustible.

Purification Methods	Crystallise the acid successively from glacial acetic acid, aqueous EtOH, and pet ether (b 60-80o). Other solvents include hot water or toluene (ca 4mL/g). The crude material can be initially purified by dissolving 30g in 100mL of hot water containing 10g of Na2CO3, boiling with 5g of charcoal for 15minutes, then filtering and adding 31mL of 1:1 aqueous HCl. The precipitate is washed with a little water and dried at 100o. [Beilstein 9 IV 956.]
