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.
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 .
What are the properties of DOTP?
Properties of DOTP - . Conversion of PET and yield of DOTP with different catalysts . Strength and elongation values of PVC including different mass ratio of DOTP and GEHTMA-3 plasticizers .
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 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).
