| | Definition | ChEBI: Trimesic acid is a tricarboxylic acid that consists of benzene substituted by carboxy groups at positions 1, 3 and 5. It is a tricarboxylic acid and a member of benzoic acids. It is a conjugate acid of a benzene-1,3,5-tricarboxylate(1-). | | General Description | Trimesic acid (TMA), also known as 1,3,5-benzenetricarboxylic acid, has a self-organized 2D molecular network structure formed by intermolecular hydrogen bonds between the carboxylic acid residues in bulk crystals. TMA can be used in the synthesis of metal-organic frameworks (MOFs), which can be used as organic linkers potentially utilized in sensors. | | Flammability and Explosibility | Notclassified | | Synthesis | Trimesic acid can be produced by Friedel – Crafts methylation of toluene or xylene with chloromethane in the presence of aluminum chloride.It is also formed by liquid-phase disproportionation of xylene in the presence of aluminum chloride.These reactions can be carried out in the gas phase at high temperature on aluminum silicate catalysts.
| | Purification Methods | Crystallise the acid from water. The trimethyl ester has m 144o (from MeOH or MeOH/H2O). [Beilstein 9 H 978, 9 IV 3747.] |
