  • What is dioctyl phthalate (DOP)?
  • Dioctyl phthalate (DOP) is used in substantial quantities in industry, primarily as a plasticiser for PVC and other polymers. One route to its production is via the esterification of 2-ethylhexanol (2EH) with phthalic anhydride (PA) using a homogeneous catalyst. The process can be carried out in batch reactors.
  • How is dioctyl phthalate formed?
  • PROCESS DESCRIPTION Chemistry Dioctyl phthalate (DOP) is formed by the di- esterification of phthalic anhydride (PA) and 2- ethylhexanol (2EH). The two main reactions taking place are as follows: Monoester formation This results in the formation of (mono) octyl phthalate (MOP): PA + 2EH -+ MOP (A) This reaction is irreversible and very fast.
  • Is DOTP a phthalate plasticizer?
  • According to this viewpoint, DOTP is only a temporary plasticizer product despite its relatively high market acceptance. Its toxicity tests are already under way. In China, more than 80% of the overall production capacity is on phthalate plasticizers and only less than 20% on non-phthalate plasticizers.
  • Which plasticizer is better – Dioctyl terephthalate or DOP?
  • Although new product like dioctyl terephthalate is more recommended, DOP accounts for more than half of the market share for plasticizers. It has been generally utilized for the flexible polyvinyl chloride (PVC) plastic production owing to its low cost.
  • Can halogen-free deep eutectic solvent promote DOP synthesis in a biphasic system?
  • In this work, the process intensification of reactive extraction strategy is proposed to promote DOP synthesis in a biphasic system, with the halogen-free deep eutectic solvent (DES) [Im:2PTSA] as dual solvent-catalyst.
  • What is non Phthalate plasticizer Dioctyl terephthalate?
  • The non-phthalate plasticizer dioctyl terephthalate (DOTP or DEHT), is an organic molecule with the chemical formula C 6 H 4 (CO 2 C 8 H 17) 2. This colorless viscous liquid is known to be a great substitute for harmful phthalates in plastic production.
