tereftalan

Tereftalan is a term that may refer to chemical compounds associated with terephthalic acid, especially terephthalates—esters or salts derived from terephthalic acid. The term is not widely used as a distinct entry in English-language chemical nomenclature, and it is often encountered as a regional or contextual variant of terephthalate.

Chemical context and structure

Terephthalic acid is benzene-1,4-dicarboxylic acid. Its derivatives include a broad family of terephthalates formed when the

Production and uses

Industrial production of terephthalic acid involves catalytic oxidation of p-xylene with air. Terephthalates are prepared by

Safety and environment

Like many organic acids and esters, terephthalate derivatives are handled under standard chemical-safety practices. Specific hazards
