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-).
Allgemeine Beschreibung
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
Not classified
Synthese
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.
läuterung methode
Crystallise the acid from water. The trimethyl ester has m 144o (from MeOH or MeOH/H2O). [Beilstein 9 H 978, 9 IV 3747.]
