Temperature- and solvent-dependent migrations of di(2

Di(2-ethylhexyl)phthalate (DEHP) is the predominant phthalic acid ester (PAE) mainly used to plasticize polyvinyl chloride (PVC) thermoplastics [1–3].Since DEHP is bound only physically on to the PVC polymer or embedded in the mesh spaces of its net, it can easily be leached into the surrounding medium, and after cycling through the ecosystem it ultimately reaches in to humans [4, 5].

The phthalic acid esters (PAEs) are the most widely used plasticizers [1]. About 8.4 million tons of PAE plasticizers are used annually, accounting for 70% of its total use worldwide. Among these, diethyl phthalate (DEP) accounts for a high proportion [2]. The extensive use of phthalate plasticizers creates great commercial value, though it

Abstract. This study investigates the determination and migration of stabilizers and plasticizers from polyethylene terephthalate (PET). Two methods [ultrasonic extraction with dichloromethane or methanol and total dissolution with phenol/tetrachloroethane (m:m/1:1)] for pre-concentration of additives in PET material were performed.

Recent Attempts in the Design of Efficient PVC Plasticizers

Because furandicarboxylic acid has a lower molecular weight (156 g/mol) than phthalic acid (166 g/mol), its esters exhibit a higher volatility compared with the esters in phthalic acid. Therefore, to lower the volatility of a potential plasticizer, alcohols with longer chains should be introduced during the esterification reaction [ 46 ].

Phthalic acid esters (PAEs) and adipates are plasticizers with high applicability in several products and building materials (e.g. cosmetics, packing) very persistent in the environment, features which render them ubiquitous pollutants. These substances can contaminate food through the environment (water, air, and soil) and/or migration from packaging materials, which creates a health concern
