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.
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 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 .
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 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 are the characteristics of DOTP produced by esterification?
One of the distinctive features of DOTP produced by esterification is the qualitative stability of subsequent batches of the product in terms of transparency (colour).
