Terephthaloyl chloride (1,4-benzenedicarbonyl chloride), the acid chloride of terephthalic acid, is used primarily to make specialty polymers, primarily aromatic polyamides, or aramids. In 1965, inventors at DuPont developed the aramid Kevlar, a copolymer of terephthaloyl chloride and p-phenylenediamine. Its first use was as a replacement for steel in racing tires.
