  • What is epoxidized fatty acid methyl ester (efame)?
  • Epoxidized fatty acid methyl ester (EFAME) is a renewable and biodegradable plasticizer that can be produced from various vegetable oils and even waste oils.
  • What are bio-based alternatives to epoxidized fatty acid methyl ester?
  • In this scenario, the last decade has witnessed an emergence of multiple bio-based alternatives, including epoxidized fatty acid methyl ester (EFAME), epoxidized soybean oil (ESO) and acetyl tributyl citrate (ATBC), as well as a surge of their application in PVC artificial leather industry.
  • How is refined soybean oil converted to fatty acid methyl ester (FAME)?
  • In this work, refined soybean oil (RSO) was first converted to fatty acid methyl ester (FAME) by enzymatic transesterification, followed by epoxidation with performic acid in situ generated via auto-catalyzed reaction of formic acid with hydrogen peroxide.
  • Does epoxidized fatty acid tri-esters bio-plasticizer reduce efame?
  • Governed by the interplay between two extra polar, PVC-compatible short esters and higher molecular weight relative to ordinary EFAME, the fogging value of the resulting epoxidized fatty acid tri-esters bio-plasticizer was found to reduce to a level comparable to DIDP.
  • Do E-Fame plasticizers outperform DOP?
  • Compared to DOP, the E-FAME plasticizer has longer aliphatic chains with higher hydrophobicity, resulting in decreased migration losses of E-FAME in distilled water. The E-FAME plasticizer did not outperform the DOP in a thorough evaluation. As a result, using E-FAME plasticizers in PVC films may increase the films’ stability.
  • Can acetylated fatty acid methyl ester-malic acid ester be a bio-based plasticizer?
  • In order to develop an eficient and sustainable plasticizer, the waste cooking oil and malic acid were used as the main raw materials in this study to synthesize a bio-based plasticizer (acetylated-fatty acid methyl ester-malic acid ester, AC-FAME-MAE) by environment-friendly methods, and the structure was characterized by FTIR and 1H NMR.
