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.

The undesired high FFA content in CSO has the potential to be converted to fatty acid esters as precursor of epoxy fatty acid ester plasticizer through acid catalyzed esterification using methanol.
Lipase catalyzed epoxidation of fatty acid methyl esters
It is possible to obtain epoxides fatty acid methyl esters by an enzymatic reaction under mild temperature and pressure conditions (45 °C, 1 atm., 250 rpm) and high selectivity by the use of Novozym 435 as biocatalyst and hydrogen peroxide as oxygen donor. The reactions were carried out with conversions higher than 99%.
- 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.
- 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.
- Can Fames be converted to epoxy plasticizer?
- Conclusion Conversion of FAMEs to epoxy plasticizer could achieve a co-production of biodiesel and bio-plasticizer. The epoxidation of FAMEs is usually performed in an oil-water bio-phase system with in situ formed peracid as an oxygen carrier.
- What is the kinetic model of epoxidized oil?
- Most of the kinetic models are developed based on the two-step mechanisms, namely that peroxy acid is formed from the reaction between formic or acetic acid and hydrogen peroxide while in the second stage epoxidized oil is produced by the reaction between peroxy acid and double bond in the oil.
- Can cooking oil methyl esters replace toxic dioctyl phthalate?

- What is the molar ratio of fatty acid methyl esters and isobutanol?
- The conversion achieved nearly 100% within 5 h under the reaction temperature, the mass ratio of catalyst to fatty acid methyl esters (FAMEs), and isobutanol to FAMEs total molar ratio of 180 °C, 0.4 % (mass), and 5.4:1, respectively. In addition, kinetic model of the transesterification reaction was developed at 150–190 °C.
