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).
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
There are different routes to produce DIB. One involves reacting high purity isobutylene over a solid acid catalyst. A second involves reacting Raffinate I with sulfuric acid which selectively condenses the isobutylene content to DIB. A third is to use an acidic ion-exchange resin to make the same condensation from Raffinate 1.
