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
What are the main types of plasticizers? - WSD Chemical
At present, phthalates esters is 80-85% of the total plasticizers. The main products: DOP, DIOP, DIDP, DINP, DBP, DIBP, DOTP. 2. Fatty acid esters have good cryogenic properties, but they are poorly soluble with polyvinyl chloride, so they can only be used as cold-resistant plasticizers and co-phthalates.
Research progress of novel bio-based plasticizers and their
The resulting epoxy tung oil methyl ester (ETM) and tung-oil-based epoxy plasticizer (TEP) showed better thermal stability and solvent resistance than DOP. Plasticizing efficiency of ETM and TEP reached 104.1% and 101.5%, respectively.
Plasticizers Derived from Biomass Resources: A Short Review
Among numerous bio based plasticizers, epoxidized fatty acid methyl ester, also known as epoxy fatty acid ester, is favorable for application as an additive material in PVC, which...
- 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.
- 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.
- 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.
- What is efame & epoxidized fatty acid methyl esters?
- In general, commercial EFAME is a mixture mainly containing epoxidized fatty acid methyl esters, and a proportion of saturated fatty acid methyl esters, depending on the source of the feedstock .
- 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.
