Research on the synthesis of trimesic acid (1, 3, 5 benzene tricarboxylic acid) derivatives and another structure based on trimethylalanisole (1-methoxy, 2,4,6-trimethylolbenzene) is reported. A general route for trimesic acid esters was found in the reaction between the desired hydroxyl compound and trimesoyl trichloride. This esterification route was used in the preparation of tribenzyl, triphenyl, tri-paracresyl, trixylenyl, and tris(2,2-dimethylamyl benzene) is reported in which a commercially available trimethylalphenol solution is used. This compound is processed through methylation with either dimethyl sulfate or menthyl iodide, followed by acetylation with acetic anhydride- pyridine, flashing and recrystallization. Most materials prepared thus far are either crystalline solids or pastes; however, a recent preparation of tris(2,2- dimethylamyl)trimesate was fluid at room temperatare showing that suitable viscosity properties may be obtained in these classes of compounds.
