1,2,4,5-Benzenetetracarboxylic acid Chemical Properties,Uses,Production

Chemical Properties

White powder. Absorbs moisture slowly if exposed to atmosphere. Soluble in alcohol, slightly soluble in water.

Uses

Pyromellitic acid (PMA) is mainly used as intermediate for powder coating. Product Data Sheet

Uses

1,2,4,5-benzenetetracarboxylic acid is used for the synthesis of the polyimide, pyromellitic octyl, etc., it is the main raw material of matting curing agent.

Definition

ChEBI: A tetracarboxylic acid that is benzene substituted by four carboxy groups at positions 1, 2, 4 and 5 respectively.

Hazard

Skin irritant, may be carcinogenic.

Purification Methods

Dissolve it in 5.7 parts of hot dimethylformamide, decolorise, filter and cool. The precipitate is collected and dried in air. The solvent is removed by heating in an oven at 150-170o for several hours. It also crystallises from water. [Beilstein 9 H 997, 9 IV 3804.]
