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.
Can tetrabutyl titanate accelerate the esterification rate of DOTP industrial production?
Therefore, intensifying the first-step reaction, such as strengthening the liquid-solid mass transfer and water removal, is important to accelerate the whole esterification rate of DOTP industrial production. A kinetic study of the esterification of PTA and 2-EH by using tetrabutyl titanate as catalyst was performed.
How to optimize the production process of Dioctyl terephthalate (DOTP)?
As 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.
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 monitor multiple parameters in DOTP production?
A more secure, effective, and quicker method to concurrently monitor multiple parameters in DOTP production is with inline process analysis using reagent-free near-infrared spectroscopy (NIRS).
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.
