Pyromellitic acid Chemical Properties,Uses,Production
Chemical Properties
White powder. Absorbs moisture slowly if exposed to atmosphere. Soluble in alcohol, slightly soluble in water.
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.
Uses
Pyromellitic acid is an eluent used in anion chromatography and forms complexes with magnesium and calcium ions. It is used as a curing agent, as an intermediate for powder coating and a cross-linking agent for alkyd resin. It is involved in the synthesis of polyimide and pyromellitic octyl.
Uses
Pyromellitic acid (PMA) is mainly used as intermediate for powder coating. Product Data Sheet
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.]
