- Can bio-based plasticizers be synthesized by epoxidizing erucic acid fatty acid methyl ester?
- In this study, a bio plasticizer was synthesized by epoxidizing erucic acid fatty acid methyl ester. The final product was compared to a conventional plasticizer. Fourier transform infrared spectroscopy (FTIR) and nuclear magnetic resonance spectroscopy (NMR) was used to confirm the structures of bio-based plasticizers (1 H NMR).
- Can fatty acid esters replace PVC plasticizers?
- This research study will help in the replacement of traditional PVC plasticizers such as citrates and phthalates with fatty acid esters, a green plasticizer that lacks a benzene ring. The main synthetic route is shown in Fig. 1.
- Which fatty acid methyl esters are used for polyvinyl chloride (PVC)?
- Epoxidized fatty acid methyl esters (E-FAME) are the essential raw material that may be utilized as an secondary plasticizer for polyvinyl chloride (PVC) [33, 34, 35].
- Can fatty acid methyl ester of erucic acid be epoxidized?
- The present study described the successful synthesis of epoxidized fatty acid methyl ester of the erucic acid ester by in situ epoxidations of fatty acid methyl ester of erucic acid. The epoxidation yield was very significant at 70 °C temperature with a 1:1.5:05 molar ratio of FAME, hydrogen peroxide, and acetic acid.
- Can bio-based plasticizers be synthesized by modifying fatty acids?
- In this study, bio-based plasticizers were synthesized by modifying fatty acids with very user-friendly approaches. Esterification and epoxidation were used to synthesize bio-based plasticizers in two steps. The synthesized plasticizer is blended with PVC in various amounts and compared to dioctyl phthalate (DOP).
- Do triesters with methyl ester functionalities have plasticizing properties?
- Especially saturated and monounsaturated triesters with methyl ester functionalities show higher absorption than potentially harmful DEHP, giving first evidence for possible plasticizing properties. van Haveren, J., Oostveen, E. A., Micciche, F., Weijnen, J. G. J.,
