1,3,5-benzoyl chloride, also known as 1,3,5-benzoyl chloride; 1,3,5-benzoyl trichloride (often abbreviated as TMC), is a light yellow solid powder at room temperature, with pungent smell. It can be obtained by the reaction of Triphosgene with pyromellitic acid under the catalysis of alkali. Pyromellitic chloride is a kind of polyamide reverse osmosis membrane and nanofiltration membrane
The monomer used. Chitosan (CS) and pyromellitic chloride (TMC) were used as reaction monomers to form a composite layer on polysulfone (PSF) / polyethersulfone (PES) blend ultrafiltration membrane by interfacial polymerization. Pyromellitic chloride is also an important intermediate for the preparation of dyes, perfumes, pharmaceuticals and resins.
