How is high-purity DOTP obtained?
High-purity DOTP is obtained through this process. Many parameters need to be monitored in order to guarantee a high reaction yield and high DOTP quality. Traditionally, the amount of reactants and products are measured in the laboratory after taking a sample from the production process.
Can CHCl-based des be used to prepare DOTP under mild conditions?
This work confirmed that ChCl-based DESs are favorable for the degradation of PET to prepare DOTP under mild conditions, which can also be used for other polymer degradation strategies. Dioctyl terephthalate (DOTP) is a new kind of green and non-toxic plasticizer.
How do you make DOTP?
There are two main methods to produce DOTP. Esterification DOTP. Hydrocarbon solvent is generally applied to the reaction with homogeneous catalysts. temperature. Reaction has occurred with titanium or titanium compound catalyst, soluble in the reaction mixture. Reaction was kept at 180 °C 270 °C. Besi des, an inert gas was used to
What are the optimal reaction conditions to obtain DOTP?
Optimum reaction conditions to obtain DOTP were evaluated as 1:3.8 for molar ratio of PET/2-EH and 13.10% for the quality ratio of catalyst/PET. Besides, when reaction temperature and time were 210 °C - 220 °C and 3 h, the productivity value of DOTP enhanced by 96.18% .
What is DOTP & how does it work?
DOTP is mainly manufactured by direct esterification. Many process parameters need to be monitored simultaneously to guarantee high product quality and high reaction throughput—something that is not possible with traditional laboratory analysis.
What are the properties of DOTP?
