tereftalati
Tereftalati, or terephthalates, are esters derived from terephthalic acid, a benzene-1,4-dicarboxylic acid. They are typically diesters formed when both carboxyl groups are esterified with alcohols, yielding compounds such as dimethyl terephthalate (DMT) and diethyl terephthalate (DET). The term also covers a broader class of diesters used as monomers in polyester synthesis.
The structure consists of a para-disubstituted benzene ring bearing two ester groups. This rigid, linear arrangement
Production and uses: Terephthalic acid is produced primarily by oxidation of p-xylene. The esters, especially DMT
Recycling and environment: PET and other terephthalate polymers can be mechanically recycled or subjected to chemical
