Plasticizers: Types, Uses, Classification, Selection & Regulation
Di-2-ethylhexyl-phthalate (DEHP, formula: C 6 H 4 (C 8 H 17 COO) 2) is a low molecular weight ortho-phthalate produced by esterification of phthalic anhydride with 2-ethyl-hexanol. It is non-volatile, colorless and odorless viscous liquid, soluble in oil, but not in water.
Synthesis, characterization and thermal behavior of
The preparation of FA/NT-doped PVC composite film materials was performed through DOTP, OT, cerium stearate and FA/NT stirring and dissolution, dispersion in PVC resin, twin-screw extrusion,...

- What is DOTP used for?
- DOTP is used to produce polymer matrices in copolymers, dyes, unsaturated polyesters, polyisocyanurate foams, textile softeners, polyurethane coatings, cementitious materials [8, 11, , , , , ] and also medical devices .
- Can DOTP be used in building materials?
- Şimşek et al. added DOTP to concrete, reporting that the electrical resistance of the concrete increased with increased amounts of DOTP. They also found that DOTP could be used in building materials due to its high corrosion resistance .
- Is DOTP a suitable material for film production?
- DOTP can be a suitable material for film production due to its above-mentioned properties. Polyvinyl alcohol (PVA) is one of the preferred film-forming materials because it is non-toxic and non-carcinogenic, and has high thermal stability, high optical permeability, high flexibility and chemical resistance [, , , ].
- What is Dioctyl terephthalate used for?
- Dioctyl terephthalate should be preferentially used to manufacture more durable and hydrophilic composite films such as fibers, disposable underpad or industrial swab, instead of toxic phthalate plasticizers. 1. Introduction
- How do you synthesize DOTP from Alcoholysis of pet?
- Zhou et al. synthesized DOTP from the alcoholysis of PET, using 2-ethyl-1-hexanol as the solvent, and choline chloride-based deep eutectic solvents as the catalysts, due to their cheapness and low toxicity. They improved the conversion amount of PET and determined the optimum parameters.
- Does DOTP contain orthophthalate?
- DOTP also does not contain orthophthalate, and it is an important alternative to the carcinogenic plasticizers that do [13, 14].
