An efficient bio-based plasticizer for poly (vinyl chloride
It is worth noting that the kind and amount of vegetable oil-based plasticizers for PVC have attracted extensive attention from the public; these plasticizers include epoxidized soybean oil (ESO), acetylated derivatives of castor oil, methyl epoxy soyate, amyl epoxy soyate, tall-oil fatty esters, di-caprylsebacate and epoxidized soybean oil

Chlorinated fatty acid methyl ester (CFAME) was synthesized by addition reaction between unsaturated FAME and chlorine gas. Briefly, dehydrated FAME (80 g) were introduced into a 250 mL three-necked flask, which was equipped with a thermometer, a magnetic stirrer and an absorbent for exhaust gas.
Research progress of novel bio-based plasticizers and their
Abstract Plasticized polyvinyl chloride (PVC) has been widely used in the world. Petroleum-based plasticizers especially phthalates have been the most common plasticizers used in PVC. However, the global petroleum resources are becoming scarce gradually, and the hygienic requirements for plasticizers are increasing. Owing to the negative impact of petroleum-based plasticizers on human health

The characteristic temperatures of the T d, T p1 and T p2 for neat PVC decreased gradually from 278.4, 291.5 and 467.4 °C to 210.7, 234.3 and 463.7 °C with increasing substitution of chlorine
- 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 acetylated fatty acid methyl ester-malic acid ester be a bio-based plasticizer?
- 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 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).
- 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 methyl ester be used as a co-plasticizer in PVC coatings?
- When combined with di-(2-ethylhexyl) phthalate (DOP) in PVC formulations, the chlorinated fatty acid methyl ester is qualified as a co-plasticizer while conferring flame retardancy upon the PVC coatings.
- 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).
