Market Overview

Iso-Octene Market Overview

Iso-octene is a chemical compound that is stable, colorless, and organic. It is widely used as a raw material in a variety of industries for the synthesis of fine chemicals such as octyldiphenylamine, octylphenol, isodecyl alcohol, and octylamine. During the dimerization of isobutylene, some n-butylene molecules react with isobutylene, resulting in the formation of dimer compounds. Iso-octene refers to the dimer compounds that have a di-isobutylene structure. It has a higher octane number, close to that of MTBE, a gasoline additive.

The olefinic nature of this chemical compound, on the other hand, is a major concern because it causes hydrogenation, which results in the formation of iso-octane. Furthermore, isobutylene dimerization produces tetradecene, trimeric dodecene, and pentapoly in addition to iso-octene. Iso-octane, which is produced by hydrogenating iso-octene, can be used as a fuel additive and chemical intermediate. The benefits of iso-octene and iso-octane include, among other things, the absence of sulphur, the absence of olefin, the absence of aroma, and the low vapor pressure, which is why these compounds are used as MTBE substitutes.
