Reactive Extraction Strategy for Synthesizing Dioctyl Phthalate

Dioctyl phthalate (DOP) is a widely used efficient plasticizer with great stability to heat and ultraviolet light, as well as the compatibility to use with PVCs resin. In this work, the process intensification of reactive extraction strategy is proposed to promote DOP synthesis in a biphasic system, with the halogen-free deep eutectic solvent (DES) [Im:2PTSA] as dual solvent-catalyst.

PROCESS DESCRIPTION Chemistry Dioctyl phthalate (DOP) is formed by the di- esterification of phthalic anhydride (PA) and 2- ethylhexanol (2EH). The two main reactions taking place are as follows: Monoester formation This results in the formation of (mono) octyl phthalate (MOP): PA + 2EH -+ MOP (A) This reaction is irreversible and very fast.

1. Introduction Dioctyl phthalate (DOP) is a kind of widely used plasticizer. The catalysts used in traditional synthesis process of DOP were mainly sulfuric acid, titanate and solid acid. The sulfuric acid cannot be reused and have other disadvantages such as equipment corrosion, more byproducts, tedious workup procedure and environmental problem.
