Professional R&D and excellent quality plasticizer chemicals

Bis (2-ethylhexyl) terephthalate commonly abbreviated DEHT (Dioctyl terephthalate or DOTP), is an organic compound with the formula C 6 H 4 (CO 2 C 8 H 17) 2. It is a non- phthalate plasticizer, being the diester of terephthalic acid and the branched-chain 2-ethylhexanol, which is referred to as octyl.

Dioctyl terephthalate (DOTP) is a plasticizer that can be prepared by alcoholysis of polyethylene terephthalate (PET) with isooctyl alcohol. Application DOTP can form a composite blend with polyaniline (PANI)-ethyene dimethacrylate (EDMA), which can be used in the fabrication of conductive films.

DOTP has a high viscosity, and oil-like structures reduce the fluidity of concrete. DOTP, which forms a mechanical barrier around the cement granules, prevents hydration of the cement with water. In their studies, they used super-plasticizer with high DOTP dosage to remove this disadvantage and to improve the workability performance of the

Global DOTP Market Size, Di Octyl Terephthalate Plasticizer . Global DOTP (Di Octyl Terephthalate Plasticizer) market stood at $ 1.16 billion in 2017 and is projected to grow at a CAGR of around 11%, to reach $ 2.16 billion by 2025, o wing to high efficiency, improved performance and low-level toxic chemicals in DOTP as compared to another phthalates.

The overall dioctyl terephthalate (DOTP) degradation efficiency during food waste composting was 98%. The thermophilic phases contributed to 76% of the overall degradation efficiency, followed by the maturation phase (22%), then the mesophilic phase (0.7%).
