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.
Electron-deficient olefins, such as enones and acryl derivatives can be epoxidized using nucleophilic oxygen compounds such as peroxides. The reaction is a two-step mechanism. First the oxygen performs a nucleophilic conjugate addition to give a stabilized carbanion. This carbanion then attacks the same oxygen atom, displacing a leaving group ...
Epoxy value derives from the Epoxy equivalent weight (EEW) or Weight Per Epoxide (WPE) and is a measure of the epoxy content of an epoxy resin or epoxy reactive diluent, or glycidyl ether. [1] This is an important parameter as it allows determination of the correct mix ratio of an epoxy system with a curing agent. [ 2 ]
Soybean oil (British English: soyabean oil) is a vegetable oil extracted from the seeds of the soybean (Glycine max). It is one of the most widely consumed cooking oils and the second most consumed vegetable oil. [2] As a drying oil, processed soybean oil is also used as a base for printing inks and oil paints.
Other vegetable oils - such as soy bean oil, [3] peanut oil, and canola oil - contain carbon-carbon double bonds, but no hydroxyl groups. There are several processes used to introduce hydroxyl groups onto the carbon chain of the fatty acids, and most of these involve oxidation of the C-C double bond.
Modern phenolic antioxidants have complex molecular structures, often including a propionate-group at the para position of the phenol (i.e. they are ortho-alkylated analogues of phloretic acid). [14] The quinone methides of these can rearrange once to give a hydroxycinnamate , regenerating the phenolic antioxidant group and allowing further ...
Epoxidized soybean oil, a part of the PVC plastics manufacturing process; Eisenbahn-Bau- und Betriebsordnung für Schmalspurbahnen, a German regulation for narrow-gauge railways; See also Esbo the local name of the town Espoo in Finland.
Besides epoxy resins based on diglycidyl ether of bisphenol A, other polymer networks have been used to produce vitrimers, such as aromatic polyesters, [4] [5] polylactic acid (polylactide), [2] polyhydroxyurethanes, [3] epoxidized soybean oil with citric acid, [6] and polybutadiene. [7]
