Synonyms: Dioctyl terephthalate, DOTP.
Gross formula: C 24 H 38 O 4
General purpose PVC plasticizer. It is used as a more environmentally friendly and safer substitute for dioctyl phthalate and other plasticizers. Products synthesized with the use of DOTP become more durable and wear-resistant due to the minimum volatility of the plasticizer. Also, the material has increased frost resistance and low viscosity.
Production technology: esterification of terephthalic acid with 2-ethylhexanol in the presence of a titanium alkoxide catalyst with further distillation of the solvent.
