CAS 1321-74-0: Divinylbenzene

Applications Divinylbenzene;m-(or p-)Divinylbenzene (cas# 1321-74-0) is a useful research chemical.

Divinylbenzene is a glycol ester that undergoes a palladium-catalyzed coupling reaction with an alkyne to produce a model system. The resulting polymer has high values of optical sensor, kinetic data, and thermal expansion. Divinylbenzene's chemical stability and particle size make it an appropriate sample preparation for various types of analytical techniques such as optical sensor, which can measure the concentration of divinylbenzene in polymers. Divinylbenzene contains nitrogen atoms that can react with fatty acids to form liver lesions in rats.

Divinylbenzene

Used as a co-monomer in the production of ion exchange beads and gel chromatography. As a monomer in the production of synthetic rubber and casting resins. Also used in polymeric core shell nanoparticles and as a crosslinking agent. It may be used as a monomer for the synthesis of highly crosslinked macroporous styrene/DVB polymers. It may also be used to synthesize monodispersed poly-DVB microspheres. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Divinylbenzene is used as a reactive monomer in polyester resins and for the synthesis of highly crosslinked macroporous styrene as well as a crosslinking agent. It acts as an intermediate in the production of ion exchange resin. Further, it is used in making rubber, petroleum production and polymeric core shell nanoparticles. In addition, it is used to synthesize monodispersed poly divinylbenzene microspheres. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio.

Divinylbenzene is a glycol ether that is used as a solvent and an intermediate in the production of polyvinyl chloride. It has been shown to be harmful to the liver in animal studies, causing lesions. It also causes an increase in the levels of water vapor in the air and high values for thermal expansion. Divinylbenzene undergoes a reaction with phosphorus pentoxide, yielding polyvinyl chloride and hydrogen gas. The mechanism of this reaction is catalyzed by palladium.

Divinylbenzene is a cross-linking agent that has the chemical formula C6H4(CH=CH)2. Divinylbenzene is produced by the reaction of ethylbenzene and diethylbenzene, which are obtained from petroleum and coal tar, respectively. Divinylbenzene is used as an activator in free radical polymerization reactions. It also has a high reactivity with chloride ions, making it useful for purifying water of organic impurities such as pesticides. The size-exclusion chromatography technique shows that divinylbenzene is composed of two different molecular species (mixture). In this experiment, divinylbenzene was found to have an activation energy of 36 kJ/mol and a thermal expansion coefficient of 2.5 x 10^5 K^-1. Divinylbenzenes are classified into two types: m-divinylbenzene and p-divinylbenzene.
