What is Dioctyl terephthalate?

Chemical properties

Clear colorless liquid

The Uses of Dioctyl terephthalate

It is used primarily as a plasticizer for polyvinyl chloride and other polymers.

The Uses of Dioctyl terephthalate

DOTP can form a composite blend with polyaniline (PANI)-ethyene dimethacrylate (EDMA), which can be used in the fabrication of conductive films. It may also be used as a plasticizer with polyvinyl chloride (PVC) to form solutions for artificial intravessel plaque.

Production Methods

DEHT is manufactured by the esterification of terephthalic acid and 2-ethylhexanol.

General Description

Dioctyl terephthalate (DOTP) is a plasticizer that can be prepared by alcoholysis of polyethylene terephthalate (PET) with isooctyl alcohol.

Toxicology

Dioctyl terephthalate is not classified as dangerous and can be expected to remain stable under normal storage and usage conditions. Dioctyl terephthalate should be handled in accordance with industry practices. Appropriate precautions including engineering controls and personal protective equipment should be observed.

Description

Dioctyl terephthalate, also known as DOTP, is used as a plasticizer in the production of PVC and other copolymers. It is the ester of terephthalic acid and 2-ethylhexanol. It is a clear, colourless liquid with a slight odour, which is insoluble in water. DOTP can be used as a direct replacement for DOP and DINP in a range of applications due to its thermal resistance, excellent durability and transparency. It is used in a variety of processes such as calendering, extrusion and injection molding.

Carcinogenicity

The carcinogenic potential of DEHT was evaluated in a 2-year study in which male and female rats were given diets containing 1500, 6000, or 12,000 ppm. There was no effect on tumor incidence, and therefore, the NOEL for tumorigenicity was at least 12,000 ppm (equivalent to 666 mg/kg/day in males and 901 mg/kg/day in females).
