Title: A Review on Plasticizers and Eco-Friendly
Citrate plasticizers have good miscibility, biodegradable, resistant to leaching and water and have legal use as additives. The demand for bioplasticizers is reported to increase from 887
A simple approach with scale-up potential towards
This approach involves only a one-step procedure that employs renewable fatty acid methyl esters and cheap chlorine gas as raw materials, thus being of great potential to enable intrinsically flame-retardant bio-plasticizers on a large scale to manufacture functional PVC artificial materials for application in fire-prone scenarios.
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.
Eco-friendly Plasticizer Chloro Fatty Acid Methyl Ester (cfame)
Epoxy fatty acid methyl ester (efame) is an environmentally-friendly vegetable oil-based plasticizer, adopts a new bio-based technology. On the one hand, one of the three chains of glyceryl linear fatty acid ester is subjected to highly selective monoglyceride esterification.
Fatty acid methyl ester
Fatty acid methyl esters ( FAME) are a type of fatty acid ester that are derived by transesterification of fats with methanol. The molecules in biodiesel are primarily FAME, usually obtained from vegetable oils by transesterification. They are used to produce detergents and biodiesel. [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.
- 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 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).
- Is cfame a flame retardant plasticizer?
- Compared with previous reported intrinsically flame- retardant plasticizer that invariably required either ex- pensive starting materials or laborious and tedious procedures, the production of CFAME was simple and cost efficient, displaying scale-up potential to en- able flame-retardant PVC artificial materials. Not applicable.
- 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 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.
