| | Dioctyl terephthalate Usage And Synthesis |
| Chemical Properties | Clear colorless liquid | | Uses | It is used primarily as a plasticizer
for polyvinyl chloride and other polymers. | | Uses | 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). |
