Di-isobutylene, or DIB, is a liquid mixture containing two isomers, 2,4,4-trimethyl-pentene-1 and 2,4,4-trimethyl-pentene-2 (sometimes referred to as DIB-1 and DIB-2).
Total isomer purity is critical in various applications where the presence of other isomers and codimers can have a detrimental impact on performance.
Janex supplies DIB in bulk parcels and isotanks.
Used as a chemical intermediate, DIB has applications in many industries including rubber chemicals, lubricant additives and coatings.
Diisobutylene CAS 25167-70-8 / EC 246-690-9
There are different routes to produce DIB:
- reacting high purity isobutylene over a solid acid catalyst;
- reacting Raffinate 1 with sulfuric acid which selectively condenses the isobutylene content to DIB; and
- using an acidic ion-exchange resin to make the same condensation as when using Raffinate 1
- bis(2,4,4-trimethylpentyl) phosphinic acid
- Iso-nonanoic acid
- Neononanoic acids
- Octenyl succinic anhydride
- Octylated diphenylamine
- Octylphenol (for resin and surfactant use)
- Photographic chemicals
- Sulfurised DIB
- Water-soluble polymers
