Preparation of Epoxidized Fatty Acid Methyl Ester with
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
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]
Derivatization of Fatty acids to FAMEs - Sigma-Aldrich
The esterification of fatty acids to fatty acid methyl esters is performed using an alkylation derivatization reagent. Methyl esters offer excellent stability, and provide quick and quantitative samples for GC analysis. The esterification reaction involves the condensation of the carboxyl group of an acid and the hydroxyl group of an alcohol.
Conversion of fatty acid methyl ester to epoxy plasticizer by
Among the alternatives of phthalates, epoxidized vegetable oil (EVO) or fatty acid alkyl esters (EFAAEs), typically epoxidized fatty acid methyl esters (EFAMs), are a type of bioplasticizer that can be produced from vegetable oil biomass or its derived FAAEs such as fatty acid methyl esters (FAMEs) which are also known as biodiesel.
Solvent-free oxidative cleavage of epoxy fatty acid methyl
This system was intended to promote catalyst reusability in the oxidative cleavage of methyl 9,10-epoxystearate (ME) to the corresponding aldehydes. No organic solvent was used in the reaction. The reaction temperature, molar ratio of ME/WO 3 /H 2 O 2 , and reaction time were optimized to 70 °C, 1/0.017/1.3, and 20 min, respectively.
- What is epoxy fatty acid methyl ester?
- Epoxy Fatty Acid Methyl Ester (EFAME),directly made from natural plant oil through etherification and epoxidation, is a kind of environmental epoxy plasticizer. 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.
- What is epoxidized fatty acid methyl ester (efame)?
- Epoxidized fatty acid methyl ester (EFAME) is an important compound used across various industries. This article provides a detailed its physical properties, mechanism of action, comparison with other compounds, applications, and safety considerations. Eastman 2 MIN READ August 29, 2024
- 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.
- What is the difference between fatty acid methyl ester and stearic acid methyl ester?
- Methyl Esters are specifically produced by esterifying fatty acids with methanol, while Stearic Acid Methyl Ester is derived from the esterification of stearic acid with methanol. In the plastics industry, Epoxidized Fatty Acid Methyl Ester (EFAME) is used primarily as a plasticizer for polyvinyl chloride (PVC).
- What is the melting point of epoxidized fatty acid methyl ester?
- The compound has a melting point ranging between -10°C to 0°C, and a boiling point around 300°C. Structurally, EFAME consists of a fatty acid chain that has been modified with an epoxide group, enhancing its stability and reactivity. The CAS number for epoxidized fatty acid methyl ester is 6084-76-0.
- How is refined soybean oil converted to fatty acid methyl ester (FAME)?
- 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 hydrogen peroxide.
