| 15. | Unreacted isobutane is recovered and recycled back to the reaction section to mix with the olefin feed.
|
| 16. | Isobutane is used as a feedstock in the petrochemical industry, for example in the synthesis of isooctane.
|
| 17. | The most common replacements are mixtures of volatile hydrocarbons, typically propane, n-butane and isobutane.

| 19. | In the Chevron Phillips slurry process for making high-density polyethylene, isobutane is used as a diluent.
|
| 20. | For example, isooctane results from combining butylene with isobutane and has an octane rating of 100 by definition.
