Preparation of Epoxidized Fatty Acid Methyl Ester with in
Epoxidized fatty acid methyl ester (EFAME) is a renewable and biodegradable plasticizer that can be produced from various vegetable oils and even waste oils. In this work, refined soybean oil (RSO) was first converted to fatty acid methyl ester (FAME) by enzymatic transesterification, followed by epoxidation with performic acid in situ generated via auto-catalyzed reaction of formic acid with
Applications of vegetable oils and their derivatives as Bio-Additives
At present, vegetable oil-based epoxy fatty acid methyl ester (EFAME) has been prepared as a new plasticizer, which can be prepared by epoxidation of fatty acid methyl ester or transesterification of epoxy vegetable oil [131].
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, whereas the epoxide group can scavenge the
Conversion of fatty acid methyl ester to epoxy plasticizer by auto
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.
Plasticizers Derived from Biomass Resources: A Short Review
With rising environmental concerns and depletion of petrochemical resources, biomass-based chemicals have been paid more attention. Polyvinyl chloride (PVC) plasticizers derived from biomass resources (vegetable oil, cardanol, vegetable fatty acid, glycerol and citric acid) have been widely studied to replace petroleum-based o-phthalate plasticizers. These bio-based plasticizers mainly include
- What is epoxy fatty acid methyl ester (efame)?
- Epoxy Fatty Acid Methyl Ester (EFAME) is a versatile, bio-based plasticizer derived from natural oils. It serves as an eco-friendly alternative to traditional phthalate plasticizers, making it an ideal choice for manufacturers and suppliers in the plastic and polymer industries who are focused on sustainability and environmental compliance.
- What is epoxidized fatty acid methyl ester?
- Epoxidized fatty acid methyl ester (EFAME) is a versatile compound with significant applications in various industries, particularly as a plasticizer and stabilizer in polymer production. Its unique chemical properties, including the presence of epoxide rings, make it an effective and eco-friendly alternative to traditional plasticizers.
- Is efame a good plasticizer for PVC products?
- It has very good process ability to PVC products with low cost, and it can partial or even totally replace phthalate plasticizer for PVC products. EFAME has the same plasticizing effect as DOP, its resistance of heat and volatility is better than DBP.
- What are epoxide groups in efame?
- EFAME contains epoxide groups, which are cyclic ether rings introduced by reacting fatty acid methyl esters with oxidizing agents. This contrasts with general Fatty Acid Esters, which are simply esters formed from fatty acids and alcohols without any specific functional groups. The chemical reactivity of EFAME is also distinct.
- Are epoxy fatty acid methyl esters safe?
- Safety: Epoxy Fatty Acid Methyl Esters (EFAME) should be handled with care to ensure safety. They are generally low in toxicity but can cause irritation. Proper safety measures include wearing protective gloves, goggles, and masks to prevent skin, eye, and respiratory tract contact.
- Are efame vapors dangerous?
- Hazards : Epoxy Fatty Acid Methyl Esters (EFAME) can pose several hazards. They may cause skin and eye irritation upon contact, leading to redness, itching, or discomfort. Inhalation of EFAME vapors or mist can irritate the respiratory tract, potentially causing coughing or difficulty breathing.
