_Binary : These plants use hot water and steam from the earth to heat another liquid, such as isobutane, which has a lower boiling point than water.
42.
By 1939 Brattain was able to use his " IRS # 1 " to distinguish between the isomers isobutane and n-butane by measuring a single wavelength of infrared radiation.
43.
Isobutane is also used as a raw material in the manufacture of propylene oxide, where it is oxidized to tert-butyl hydroperoxide and subsequently reacted with propylene to yield propylene oxide.
44.
As with the previously described mechanisms, the heavy carbocations may at some point undergo a hydride transfer from isobutane to yield a C12 C16 isoparaffin and a t-butyl cation.
45.
Super Octanos is using existing inventories of isobutane to continue its scheduled production of methyl tertiary butyl ether, a gasoline additive used to boost octane and add oxygen to make fuel burn cleaner.
46.
Low purity makeup isobutane feedstock ( typically 95 % vol isobutane ) normally originates from an external De-isobutanizer ( DIB ) tower and is fed directly to the alkylation unit reaction zone.
47.

48.
Its gaseous emissions are composed of 22 % methane, 19 % sulfur, 12 % naphthalene, 10 % argon, 6 % isobutane, 2 % xylene, and 29 % unknown gases.
49.
More colloquially it is used to refer to the 7 / 16 " UNEF threaded valve used on disposable butane and / or butane / isobutane / propane mix cartridges used in some backpacking stoves.
50.
Olefins in gasoline are responsible for the formation of polymeric deposits in storage C 3-C 4 olefins and isobutane that are essential feeds for the alkylation process and the production of polymers such as polypropylene.
