Combining Renewable Eleostearic Acid and Eugenol
The recent studies on sustainable plasticizer mainly focus on raw material source, synthesis method and plasticization, but the effect of chemical functional groups (epoxy group and ester group) of sustainable plasticizer on compatibility and thermal stability of plasticized polyvinyl chlorid (PVC) materials has been ignored. In this study, two kinds of sustainable plasticizers (eleostearic
Plasticizers Derived from Biomass Resources: A Short Review

Conversion of fatty acid methyl ester to epoxy plasticizer by
Fatty acid methyl esters (FAMEs) can be converted to epoxy plasticizer by in situ auto-catalyzed formation of performic acid (PFA) in a bi-phase reaction system. However, mass transfer effect could be neglected in a well-stirred reaction system. A pseudo-homogenous kinetic model was thus developed to describe the kinetics of FAME epoxidation.
Castor Epoxy Fatty Acid Alkyl Ester Estolides as
The unsaturation was epoxidized, resulting in a bifunctional epoxy fatty acid alkyl ester estolide. The bioplasticizers were compounded with PVC and were evaluated for their functionality and compared with commercial phthalate plasticizer diisononyl phthalate (DINP) and nonphthalate 1,2-cyclohexanoic acid diisononyl ester (DINCH).
- Can epoxidized fatty acid Isobutyl esters be used as biobased plasticizer in PVC?
- However, few studies on the preparation and application of epoxidized fatty acid isobutyl esters (Ep-FABEs) as the biobased plasticizer in PVC were reported. In this paper, a two-step approach, including transesterification and epoxidation, was adopted to prepare Ep-FABEs using biodiesel as the raw material, as shown in Fig. 1.
- What are biobased plasticizers?
- To date, biobased plasticizers mainly include epoxidized fatty acid methyl esters (Ep-FAMEs) , aliphatic diesters , epoxidized triglycerides , and citrate plasticizers .
- Does epoxidized fatty acid 2-ethylhexyl ester increase migration resistance?
- The obtained epoxidized fatty acid 2-ethylhexyl esters showed better migration resistance than that of Ep-FAMEs . The transesterification reaction proved to be a simple and efficient method to increase the molecular weight of Ep-FAMEs and hence improve their migration resistance.
- Why are EP-FAME fatty acid methyl esters so popular?
- Among them, Ep-FAMEs have received considerable attention because of its high plasticizing efficiency and low cost, which can be directly acquired from unsaturated fatty acid methyl esters by using percarboxylic acids or organic/inorganic peroxides , , , .
- Are EP-Fabes a good plasticizer for PVC industry?
- Moreover, Ep-FABEs exhibited better resistance to extraction and migration than another biobased plasticizer Ep-FAMEs. In summary, Ep-FABEs derived from renewable sources have good potential as an environmentally friendly plasticizer in PVC industry.
- What is the epoxidation procedure of Fabes?
- The epoxidation of FABEs was carried out in the presence of formic acid and hydrogen peroxide according to the procedure described in Wu et al . Briefly, FABEs (100 g) and formic acid (5.09 g) were placed into a 250 ml flask equipped with an agitator and a dripping device for hydrogen peroxide.
