  • 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.
  • 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.
  • Can enzymatic conversion of waste oil to epoxidation produce efame plasticizer?
  • However, this work illustrated that enzymatic conversion of waste oil to FAME followed by epoxidation with in situ generated PFA was a possible way to produce EFAME plasticizer.
  • Does sulfuric acid affect epoxidation?
  • Mineral acid such as sulfuric acid could significant improve the rate of epoxidation; however, the cleavage of epoxy group was also strengthened, resulting in lower EV of the EFAME product. Surfactants showed significant negative effects on epoxidation, and Tween 20 demonstrated stronger inhibition than SDS even at a low concentration (0.5%).
  • Is efame bleached by PFA & H2 O 2?
  • The color of WCO FAME became lighter after epoxidation (Figure S2), corroborating that the FAME was “bleached” by PFA and H 2 O 2. A mass balance was obtained according to experiments for preparation of EFAME from RSO and WCO, respectively, as shown in Fig. 4 a, b. For RSO, a high yield (95.2 g/100 g RSO) of EFAME could be obtained.
  • Which surfactant affects epoxidation of RSO Fame?
  • An anionic surfactant (sodium dodecyl sulfate, SDS) and nonionic surfactant (Tween 20) were added to study their influences on epoxidation of RSO FAME as shown in Fig. 3 b, c. SDS showed some negative effects on the kinetics of epoxidation of FAME, while very significant negatives were observed for Tween 20.
