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.
The latex-modified epoxy aqueous dispersions are treated by evaporation techniques. Nitrile latices were used in the study. [88] Modification of soybean oil that has been epoxidized and then reacted with acrylic acid will produce waterborne epoxy acrylates that are also based on some renewable content. The corrosion resistance properties are ...
The epoxy value is defined as the number of moles of epoxy group per 100g resin. So as an example using an epoxy resin with molar mass of 382 and that has 2 moles of epoxy groups per mole of resin, the EEW = 382/2 = 191, and the epoxy value is calculated as follows: 100/191 = 0.53 (i.e. the epoxy value of the resin is 0.53).

A compound containing the epoxide functional group can be called an epoxy, epoxide, oxirane, and ethoxyline. Simple epoxides are often referred to as oxides. Thus, the epoxide of ethylene (C 2 H 4) is ethylene oxide (C 2 H 4 O). Many compounds have trivial names; for instance, ethylene oxide is called "oxirane".
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]
Epoxy is the family of basic components or cured end products of epoxy resins. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. The epoxide functional group is also collectively called epoxy. [1] The IUPAC name for an epoxide group is an oxirane.
Soybean oil, meal and beans. To produce soybean oil, the soybeans are cracked, adjusted for moisture content, heated to between 60 and 88 °C (140 and 190 °F), rolled into flakes, and solvent-extracted with hexanes. The oil is then refined, blended for different applications, and sometimes hydrogenated. Soybean oils, both liquid and partially ...
In its application as an epoxy oil, [8] vernonia oil competes with soybean or linseed oil, which supply most of the market for these applications. Its low viscosity makes it more desirable than fully epoxidized linseed or soybean oils. It is comparable to partially epoxidized linseed or soybean oil. [9]
