Styrene and divinylbenzene are two common chemical raw materials, which are widely used in the chemical industry. Although they all contain "benzene" and "ethylene" in the name, there are actually many differences between them.

from the chemical structure, the structural formula of styrene is C6H5-CH = CH2, and the structural formula of divinylbenzene is C6H5-CH = CH-C6H5. It can be seen that the styrene molecule contains only one benzene ring, while the divinylbenzene molecule contains two benzene rings, so there are obvious differences in structure.

in the field of application, styrene is mainly used in the production of polystyrene (PS), ABS copolymer, SBR rubber, etc., while divinylbenzene is mainly used in the production of epoxy resin, unsaturated polyester resin, maleic anhydride acid resin and so on. It can be seen that there are obvious differences between the two in the application field, and each has a wide range of uses.

In addition, in the production process, styrene is generally obtained by steam cracking of ethylbenzene or cracking of benzene and styrene, while the production of divinylbenzene is usually obtained by the synthesis reaction of benzene and ethylene. It can be seen that the production process of the two is also different, which is one of the important reasons for the difference in their properties and uses.

In general, although styrene and divinylbenzene are very similar in chemical name, there are obvious differences in their structure, use and production process in the actual chemical production and application process. For those engaged in the chemical industry, an in-depth understanding of the characteristics and differences between these two chemical raw materials will help to better select and apply them, improve production efficiency, reduce production costs, and promote the development of the chemical industry.
