The unique activity of catalyst in the epoxidation of soybean
In the next part of the performed experiments, products of soybean oil epoxidation: ESBO H 2 SO 4, ESBO Zerolit325, ESBO Amberlyst15, and ESBO Novozym435, were used in the fusion process with bisphenol A. Product of epoxidation in a presence of Zeolite Y, due to the very low epoxy value, was not use in the further investigations.
Epoxidation of soybean oil enhanced by microwave radiation
The epoxidation of the oil was performed by reaction with peracetic acid generated in situ by reaction between hydrogen peroxide (HP) and acetic acid. Acetic acid and HP 35 wt% were used instead of the commonly used formic acid and HP 60 wt% to reduce the risk of detonation and corrosion.
Epoxidized soybean oil
Epoxidized soybean oil ( ESBO) is a collection of organic compounds obtained from the epoxidation of soybean oil. It is used as a plasticizer and stabilizer in polyvinyl chloride (PVC) plastics. ESBO is a yellowish viscous liquid. [3] Manufacturing process [ edit] Epoxidized linolein, a major component of ESBO.
RECENT ADVANCES IN EPOXIDATION OF VEGETABLE OILS - JETIR
oils like linseed oil and castor are used for industrial purposes. Research on development of vegetable oil based polymeric materials, including additives, bio-composites and nanocomposites, has attracted increasing attention in recent years. II. EPOXIDATION Epoxidized oil contains epoxide groups or oxirane rings.
Comparative Analysis on the Epoxidation of Soybean Oil using
2.2 Synthesis of Epoxidized Soybean Oil (ESBO) Epoxidation of soybean oil was carried out by placing 1 mol of soybean oil and 0.5 mol of formic acid in a three-neck flask equipped with a thermometer and magnetic stirrer. The flask containing the solution was submerged in an oil bath on top of a magnetic stirring hot plate.
- How is soybean oil epoxidized?
- The epoxidation of soybean oil can be performed by several ways. The traditional way consists in the epoxidation of the oil by means of a peroxycarboxilic acid, produced in situ by reaction between hydrogen peroxide and a carboxylic acid (acetic or formic) [6], [11]. Sometimes a liquid acidic catalyst is used (sulfuric or phosphoric).
- Which side reaction is most important in the epoxidation of soybean oil?
- Author to whom correspondence should be addressed. The epoxide ring opening reaction (ROR) can be considered as the most important side reaction occurring in the epoxidation of soybean oil reaction network. This reaction consistently reduces the selectivity to epoxidized soybean oil (ESBO).
- What is epoxidized soybean oil (ESO)?
- Epoxidized soybean oil (ESO) was developed through the synthesis of conventional soybean oil by applying deep eutectic solvent catalysts, such as choline chloride–oxalic acid (DES-02) and choline chloride–butyric acid (DES-06) followed by three steps of washing neutralization processes.
- How is epoxidation of soybean oil performed?
- Epoxidation of soybean oil using DES catalysts Epoxidation of soybean oil was performed by reacting soybean oil with performic acid, which was generated in situ by the interaction of formic acid with hydrogen peroxide (Yang et al., 2021, Zhao et al., 2013).
- How Zeolite Y is used in epoxidation of soybean oil?
- Moreover, before the application in the reaction, in the case of epoxidation of soybean oil in a presence of Zeolite Y, the catalyst, was calcinated for 4 h in 400 °C, then placed in exsiccator where it cooled down to the room temperature, and was kept there until the time of the reaction.
- What is the epoxy value of epoxidized soybean oil?
- Obtained epoxy value of the epoxidized soybean oil in the presence of Amberlyst 15 is lower than these presented by Fiszer et al. (2003), who obtained the product of the reaction in the presence of Amberlyst 15, with EV amounting to 0.330 mol/100 g.
