1,3,5-benzoyl chloride; pyromellitic chloride

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. It is commonly used to prepare polybenzoylamine membrane. 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.
