Synthesis and Properties of Isosorbide-Based Eco-friendly
To the best of our knowledge, this is the first study to introduce isosorbide di epoxidized oleate as a green plasticizer for PVC processing. Here, isosorbide was esterified with a series of fatty acids, and the isosorbide diester plasticizer with short alkyl chain length showed high compatibility with PVC.
Synthesis and properties of castor oil based plasticizers
Plasticizers prepared from vegetable oils mainly include epoxy vegetable oils, 5–8 and epoxidized fatty acid esters. 9 In these types of plasticizers, the presence of the epoxy group makes the plasticizers have a better plasticizing effect on PVC and plays a role as stabilizer. 10 When heated, PVC undergoes autocatalytic dehydrochlorination
Research progress of novel bio-based plasticizers and their
The synthesis route of epoxidized castor oil-based ester is shown in Scheme 1. They added these prepared plasticizers to PVC as the main plasticizer and compared their plasticizing properties with epoxidized soybean oil (ESO) and dioctyl terephthalate (DOTP).
Chitosan-based films with alternative eco-friendly
The chemical structure of newly synthesized plasticizers was verified by gas chromatography with mass detector, infrared spectroscopy and H NMR; and their acid, epoxy, iodine, and...
Synthesis of an efficient bio-based plasticizer derived
In order to develop an efficient 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 1 H NMR.
- 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.
- 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.
- 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 epoxidized cottonseed oil be used as an eco-friendly plasticizer?
- Research done by Carbonell-Verdu et al. utilized epoxidized cottonseed oil (ECSO) as an eco-friendly plasticizer for PLA. The plasticization process was carried out through melt extrusion of PLA compositions containing 0%–10% ECSO.
- What are biobased plasticizers?
- To date, biobased plasticizers mainly include epoxidized fatty acid methyl esters (Ep-FAMEs) , aliphatic diesters , epoxidized triglycerides , and citrate plasticizers .
- What are alternative plasticizers?
- Alternative plasticizers are still being sought, including oils such as palm oil (Hasan et al., 2020), rosehip seed oil (Darie-Niță et al., 2021), epoxidized chia seed oil (Dominguez-Candela et al., 2021), epoxidized soybean oil (Alhanish & Abu Ghalia, 2021) olive oil or corn oil ( Giannakas et al., 2017) and fatty acids ( Srinivasa et al., 2007 ).
