What is dioctyl terephthalate used for?
What is dioctyl terephthalate used for?
Dioctyl terephthalate is primarily used as a plasticizer for PVC, and as a replacement for ortho-phthalates in a wide range of applications. As well as its uses in the plastics industry it is also commonly used in the paints and varnishes industry.
Is DEHT toxic?
ECHA (2012) concluded that DEHT is not acutely toxic following repeated dermal application but may cause moderate dermal irritation. A GLP compliant 104-week carcinogenicity and chronic toxicity study was conducted in accordance with EPA OPPTS 870.4200 guideline.
How is DOTP made?
Production. One method of manufacture entails the transesterification of dimethyl terephthalate with 2-ethylhexanol: A second method of manufacture is a direct esterification of terephthalic acid with 2-ethylhexanol: C6H4(CO2H)2 + 2 C8H17OH → C6H4(CO2 C8H17)2 + 2H2O.
Is DEHT a phthalate?
Despite the similar name, DEHT is not a phthalate. DEHT (Di-(2-ethylhexyl) terephthalate), also known as dioctyl terephthalate, is a general-purpose non-phthalate plasticizer.
What is plasticizer DOP?
Product description. Eastman™ DOP Plasticizer (Bis(2-Ethylhexyl) Phthalate) is a light colored, low volatility, odorless liquid. It is the most widely used all-purpose plasticizer offered by Eastman™ for use with polyvinyl chloride (PVC) resins. It is insoluble in water and has a viscosity of 56 cP at 25°C.
What is phthalate free?
Non-phthalates are essentially plasticizers that are free of phthalates. While low exposures to phthalates are harmless, there has been recent research suggesting the potentially negative impacts a high exposure of phthalates can have on our health. As such, many consumers are switching non-phthalate plasticizers.

Is the diester of terephthalic acid a phthalate?
It is a non- phthalate plasticizer, being the diester of terephthalic acid and the branched-chain 2-ethylhexanol. This colorless viscous liquid used for softening PVC plastics is known for chemical similarity to general purpose phthalates such as DEHP and DINP, but without any negative regulatory pressure.
Which is the correct formula for Dioctyl terephthalate?
Infobox references. Dioctyl terephthalate (bis(2-ethylhexyl) benzene-1,4-dicarboxylate or Di(2-ethylhexyl) terephthalate), commonly abbreviated DOTP or DEHT, is an organic compound with the formula C 6H 4(CO 2C 8H 17) 2. It is a non-phthalate plasticizer, being the diester of terephthalic acid and the branched-chain 2-ethylhexanol.
Which is safer DOTP or ethylhexanol terephthalic acid?
A second method of manufacture is a direct esterification of terephthalic acid with 2-ethylhexanol : DOTP is a general purpose plasticizer that is considered safer than ortho – phthalate plasticizers due to its reduced toxicity profile.
