  • What is DOTP Dioctyl terephthalate?
  • TCC’s ChemFlexx DOTP Dioctyl terephthalate (bis (2-ethylhexyl) benzene-1,4-dicarboxylate), commonly abbreviated DOTP, is an organic compound with the formula C 6 H 4 (C 8 H 17 COO) 2. It is the most important of the phthlte-free plasticizers, being the diester of terephthalic acid and the branched-chain 2-ethylhexanol.
  • Can terephthalic acid be used as a substitute for phthalates?
  • This colorless viscous liquid is known to be a great substitute for harmful phthalates in plastic production. One of the methods of manufacturing DOTP is by direct esterification of purified terephthalic acid (TPA) and the branched-chain 2-ethylhexanol (2-EH) [ 3 ].
  • How is high-purity DOTP obtained?
  • High-purity DOTP is obtained through this process. Many parameters need to be monitored in order to guarantee a high reaction yield and high DOTP quality. Traditionally, the amount of reactants and products are measured in the laboratory after taking a sample from the production process.
  • How is terephthalic acid made?
  • One of the methods of manufacturing DOTP is by direct esterification of purified terephthalic acid (TPA) and the branched-chain 2-ethylhexanol (2-EH) [ 3 ]. TPA comes in pelleted form, 2-EH as a liquid solution, and they are mixed together in an industrial reactor in a 1:2 ratio.
