| This reaction is initiated by the electrophilic protonation of isobutylene. |
|
| Electrophilic addition of the t-butyl cation to isobutylene completes the process and regenerates the t-butyl cation. |
|
| The end result is the addition of isobutane to isobutylene to form isooctane, the molecule that is the basis of octane ratings seen at the gas pumps. |
|
| The second chapter focuses on isobutylene oxide end-uses, the third one gives summary on a number of patents. |
|
| The C4 Oleflex process uses catalytic dehydrogenation to convert isobutane to isobutylene. |
|
| Gevo has also patented a process by which isobutylene is dimerized to p-xylene, the petrochemical precursor to terephthalic acid. |
|
| Based on a copolymer of isobutylene and maleic anhydride, the fiber will be used in the development of new specialty fiber superabsorbents. |
|
| It is made from blending chemicals such as isobutylene and methanol, and has been used since the 1980s as an additive for unleaded petrol to achieve more efficient burning. |
|
| Several Catofin units using HGM for isobutylene production have gone on-stream since 2011, all confirming the advantages of HGM technology at full commercial scale. |
|
| Lummus Technology will be providing technology for a world scale steam cracker complex comprising ethylene, butadiene, benzene, isobutylene and MTBE units. |
|
| This complex has units producing polyethylene, synthetic rubbers, latex, propylene glycol, pyrolysis benzene and fractions of butene, butylene and isobutylene. |
|
| Propylene is a building block material used in the production of films and packaging, while isobutylene is a key ingredient for fuels and synthetic rubber. |
