U.S. PRODUCERS’ QUESTIONNAIRE DIOCTYL TEREPHTHALATE (DOTP
U.S. Producers’ Questionnaire ‐ DOTP Page 5 I‐5. Related importers/exporters.‐‐Does your firm have any related firms, either domestic or foreign, that are engaged in importing DOTP from Korea into the United States or that are engaged in exporting DOTP from Korea to the United States?
- What are the production methods of DOTP?
- The production methods of DOTP can generally be divided into three categories: 1) direct esterification of terephthalic acid (PTA) with 2-ethylhexanol (2-EH) ; 2) alcoholysis of polyethylene tere-phthalate (PET) with 2-EH ; 3) transesterification of dimethyl terephthalate (DMT) with 2-EH .
- How to optimize the production process of Dioctyl terephthalate (DOTP)?
- AbstractAs a green plasticizer, the industrial production of dioctyl terephthalate (DOTP) is still facing the problem of high energy consumption. To optimize the production process and reactor, it is essential to understand the kinetic behavior of reaction system.
- How is DOTP produced?
- At present, the industrial production of DOTP by direct esteri-fication of PTA and 2-EH is usually carried out in a reactive distil-lation unit, due to the reversibility of the esterification reaction. In this process, a great deal of heat is consumed to ensure the gener-ated H2O in the reactions can be removed in time.
- Is Dioctyl terephthalate a good substitute for Paes Plasti-cizers?
- Among which, dioctyl terephthalate (DOTP), as a “green” plasti-cizer, has gradually become an excellent substitute for PAEs plasti-cizers due to its excellent properties, such as low volatility, lower viscosity, non-carcinogenicity and high electrical resistance .
- What type of catalyst is used to produce DOTP?
- In the selection of catalyst, strong acid catalysts, such as sulfuric acid and p-toluenesulfonic acid, were usually used to produce DOTP in the past . However, they were gradually phased out due to cor-rosion of equipment and generation of waste acid. However, tetra-
