Title: A Review on Plasticizers and Eco-Friendly
Plasticizers are chemical additives added into polymers to influence desirable mechanical properties such as processability and ductility. These properties are a result of the association of...
A targeted review of bio-derived plasticizers with flame
Similar to the above-mentioned examples with soybean oil, another group pursued the use of unsaturated fatty acid methyl ester (FME), which was chlorinated (chlorine reacting with the unsaturated double bonds—Fig. 3) and was used as a co-plasticizer for PVC coating. While adding additional chlorine content to the plasticizer is a way to
Synthesis and Properties of Isosorbide-Based Eco-friendly
In this study, isosorbide-based eco-friendly and effective plasticizers were synthesized and characterized. Isosorbide esterification was conducted using fatty acids with different alkyl-chain lengths; the optimal degree of isosorbide esterification was obtained after 6 h reaction at 220 °C with a short alkyl-chain fatty acid in the presence of the catalyst Ti(OBu)4. Isosorbide-based
Synthesis and Properties of Isosorbide-Based Eco-friendly
Thus, the plasticizers synthesized in this study, particularly isosorbide di epoxidized oleate, could be used as eco-friendly and effective plasticizers for practical PVC applications....
Conversion of fatty acid methyl ester to epoxy plasticizer by
Fatty acid methyl esters (FAMEs) can be converted to epoxy plasticizer by in situ auto-catalyzed formation of performic acid (PFA) in a bi-phase reaction system. However, mass transfer effect could be neglected in a well-stirred reaction system. A pseudo-homogenous kinetic model was thus developed to describe the kinetics of FAME epoxidation.
- 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 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 chlorine fatty acid methyl ester (cfame)?
- Chlorinated fatty acid methyl ester (CFAME) was synthe- sized by addition reaction between unsaturated FAME and chlorine gas. Briefly, dehydrated FAME (80 g) were in- troduced into a 250 mL three-necked flask, which was equipped with a thermometer, a magnetic stirrer and an absorbent for exhaust gas.
- Is liquefied wood flour ester a good plasticizer?
- The liquefied wood flour ester (PWF) showed good miscibility with PLA and good plasticization efficiency as shown by differential scanning calorimetry (DSC) and tensile testing. Tensile strain at break increased from a few percent for pure PLA to over 100 and 300% for the materials containing 10 and 30 wt-% of PWF.
