A review of common non-ortho-phthalate plasticizers for use in food

Available assessments from US CPSC, EFSA, other governmental and non-governmental organizations, and published toxicology studies were used to show that these plasticizers are generally well-studied and demonstrate low toxicity with a focus on potential carcinogenicity, reproductive, developmental, and endocrine related adverse effects as well a...

pseudo-homogeneous kinetic modeling of dioctyl terephthalate (dotp

Pseudo-homogeneous kinetic modeling of dioctyl terephthalate (DOTP

The reaction process of direct esterification is shown in Fig. 1. It is a two-step consecutive reaction. First, mono-2-ethylhexyl terephthalate (MEHTP) is obtained by esterification of PTA and 2-EH in the presence of catalyst. Then, the MEHTP further reacts with 2-EH to produce DOTP. Note that PTA is almost insoluble in liquid-phase system at

Bis(2-ethylhexyl) terephthalate

Use DEHT is a general purpose plasticizer that is considered safer than ortho - phthalate plasticizers due to its reduced toxicity profile. The terephthalates exhibit none of the peroxisome proliferation of liver enzymes that some ortho - phthalates have shown in several studies. [3]

alcoholysis of polyethylene terephthalate to produce dioctyl

Alcoholysis of polyethylene terephthalate to produce dioctyl

Dioctyl terephthalate (DOTP) is a new kind of green and non-toxic plasticizer. The traditional process to prepare DOTP is costly and complicated, thus it is very necessary to find an efficient and environmentally-friendly way to obtain DOTP. In this study, we prepared DOTP from the alcoholysis of polyethylen

An efficient cold-resistant strategy: Synthesis and application

Here, we report an oil extracted from Hibiscus rosa-sinensis, epoxidized by one-pot epoxidation, and named Epoxidized Hibiscus Oil (EHO) as a possible primary bio-based plasticizer and the oil extracted from cinnamon, named Raw Cinnamon Oil (RCO), as a secondary plasticizer. Polyvinyl chloride (PVC) plasticized films were prepared with EHO (10/30/50 wt%), a combination of both Epoxidized

Synthesis and application of high-stability bio-based plasticizer

Our team had done a lot of work in the field of new environmentally friendly plasticizers [41], [42], especially in vegetable oil-based plasticizers. In this article, we prepared a high-stability bio-based plasticizer derived from ricinoleic acid through a four-step reaction and blended it with PVC to prepare samples.
