Mixture of isomers

In organic chemistry, an isomer mixture is a mixture of substances composed of two or more isomers . These isomers can be constitutional or stereoisomers ( mixture of stereoisomers ). Mixtures of isomers of different constitutional isomers exist in cracking gases, for example, where isomers of different short-chain hydrocarbons are present as a mixture of isomers.

Example: DIPN isomer mixture

Mixtures of isomers can often be found in technical products; an example of this is the DIPN isomer mixture , which contains numerous isomers of diisopropylnaphthalenes. Such technically important isomer mixtures often have their own CAS number as a mixture , although their individual components may already be registered under other CAS numbers.
