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.
Conversion of fatty acid methyl ester to epoxy plasticizer by
Among the alternatives of phthalates, epoxidized vegetable oil (EVO) or fatty acid alkyl esters (EFAAEs), typically epoxidized fatty acid methyl esters (EFAMs), are a type of bioplasticizer that can be produced from vegetable oil biomass or its derived FAAEs such as fatty acid methyl esters (FAMEs) which are also known as biodiesel.

Plasticizers Derived from Biomass Resources: A Short Review
Ester-amide of ricinoleic acid, as shown in Figure 22, is synthesized and used as primary plasticizer to replace phthalate plasticizers in PVC materials [ 105 ]. Tg of PVC materials blended with 40 wt % of ester-amide of ricinoleic acid reaches 13.5 °C. Figure 22. Synthesis of ester-amide of ricinoleic acid.
- What are epoxidizing agents?
- For most of the works on preparation of EVO or EFAMEs, short chain peracids (usually peracetic acid and performic acid (PFA)) generated in situ by reaction of a carboxylic acid with hydrogen peroxide (HP) under the catalysis of various acid catalysts, are used as an epoxidizing agent.
- 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 epxodiation of Fames with peroxycarboxylic acid?
- The epxodiation of FAMEs with peroxycarboxylic acid as the oxygen carrier is complicated where the reactions take place in an emulsion system. The epoxidation reaction majorly take place at the water-oil interface, and mass transfer may become a limiting-step to the overall reactions.
- Does stirring speed affect the epoxy value of epoxidized Fames?
- It can be known that increasing stirring speed from 300 rpm to 900 rpm actually showed no significant effect on the epoxy value of the obtained epoxidized FAMEs, indicating that the diffusion is not a limiting step under the stirring condition employed in the experiments (300–900 rpm).
