Diisobutylene (DIB), known by its CAS number 25167-70-8, is a C8 olefin that has garnered significant attention in the chemical industry due to its robust properties and versatile application as an intermediate. Its molecular composition, primarily consisting of 2,4,4-trimethylpentene isomers, makes it a highly reactive and valuable compound for a multitude of synthesis processes. Understanding the intricacies of its properties and production is key to appreciating its market impact.

The defining characteristic of Diisobutylene is its chemical reactivity, largely attributed to the double bond within its molecular structure. This reactivity allows it to participate in various chemical reactions, including alkylation, halogenation, and carbonylation, making it an ideal starting material for creating complex chemical compounds. This inherent property is central to its use in applications like the production of octylphenol, a critical component in the synthesis of surfactants and antioxidants, which are vital for industries ranging from detergents to plastics.

The synthesis of Diisobutylene typically involves the dimerization of isobutylene. Various methods are employed, including the use of solid acid catalysts or reacting mixed C4 streams with sulfuric acid or acidic ion-exchange resins. While these processes are effective, challenges can arise in achieving high purity due to the formation of by-products with similar boiling points, such as dimethylhexene and other trimethylpentenes. Overcoming these separation challenges to obtain high-yield, high-purity Diisobutylene is a focus for manufacturers like NINGBO INNO PHARMCHEM CO.,LTD., ensuring a reliable supply for demanding applications.

The market impact of Diisobutylene is substantial, driven by its wide-ranging diisobutylene uses.
