High-purity olefin for synthesis processes
Due to its high purity, diisobutene (DiB) is used as an intermediate for the production of UV stabilizers, high-performance lubricants and special polymer resins.
What is diisobutene and what is it used for?
Diisobutene (also: isooctene), DiB for short, is a branched C8 olefin. Due to its high-purity of >99.5 %, DiB can be used as an intermediate for the production of high-quality specialty chemicals.
In particular, DiB is used as a raw material or intermediate for the synthesis of 3,5,5 trimethylhexanal, isononanoic acid and 3,5,5 trimethylhexanol, but also for the production of organic peroxides, antioxidants, agrochemicals, resins, pharmaceuticals, fine chemicals, organic acids, fragrances, lubricants, polyurethanes and solvents.
A few technical details:
Diisobutene is a colorless, highly flammable liquid, with a very low flash point of -6°C (21°F) and very low water solubility. Diisobutene must be stored under strictly controlled conditions (diisobutene is registered under REACH as an "isolated/transported intermediate") at temperatures of <30°C and in the absence of oxygen.
Here you can find additional product information (e.g. technical data sheet, SDS, etc.) on DiB.
You can find all information about our specialties at a glance in our brochure.
Where is diisobutene produced and how is it transported?
In our state-of-the-art C4 Verbund, we process various exclusively C4-based feedstock streams from steam crackers and refineries, such as crude-C4 (so-called CC4) or FCC-C4 (fluid catalytic cracking-C4). The high C4 purity of the intermediates enables the production of high-quality derivatives. The use of special purification and processing technologies safely eliminates any undesirable impurities. Our continuous production ensures the constant and reliable availability of our products. Diisobutene is produced at Evonik's largest production location in Marl, Germany. We offer our customers diisobutene in tank trucks, tank containers and rail tank cars.
