Polyunsaturated vegetable oils are widely used as precursors to epoxidized oil products because they have high numbers of carbon-carbon double bonds available for epoxidation. [4] The epoxide group is more reactive than double bond, thus providing a more energetically favorable site for reaction and making the oil a good hydrochloric acid ...
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 ...
Soybean oil is one of many drying oils, which means that it will slowly harden (due to free-radical-based polymerization) upon exposure to air, forming a flexible, transparent, and waterproof solid. Because of this property, it is used in some printing ink and oil paint formulations.
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.
The structure below shows the major component of castor oil which is composed of the tri-ester of rincinoleic acid and glycerin: Major component of castor oil. Other vegetable oils - such as soy bean oil, [3] peanut oil, and canola oil - contain carbon-carbon double bonds, but no hydroxyl groups
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).

Shares of the Indiana-based drugmaker rose 2.6% to $905.32 after Lilly's announcement on Tuesday, while stocks of telehealth companies that offer compounded versions of weight-loss drugs fell in ...
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".
