Isobutane is the principal feedstock in alkylation units of refineries. Using isobutane, gasoline-grade "blendstocks" are generated with high branching for good combustion characteristics. Typical products created with isobutane are 2,4-dimethylpentane and especially 2,2,4-trimethylpentane. [7] Typical acid-catalyzed route to 2,4-dimethylpentane.
Isobutane is partly made available from the catalytic reforming and from the atmospheric distillation, although the proportion of the isobutane produced in a refinery is rarely sufficient to run the unit at full capacity and additional isobutane needs therefore to be brought to the refinery. The economics of the international and local market ...
Isopropyl group Methyl group. In organic chemistry, an alkyl group is an alkane missing one hydrogen. [1] The term alkyl is intentionally unspecific to include many possible substitutions.
Butane (/ ˈ b juː t eɪ n /) is an alkane with the formula C 4 H 10.Butane exists as two isomers, n-butane with connectivity CH 3 CH 2 CH 2 CH 3 and iso-butane with the formula (CH 3) 3 CH. ...

The environmental organization Greenpeace provided funding to a former East German refrigerator company to research alternative ozone- and climate-safe refrigerants in 1992. The company developed a hydrocarbon mixture of propane and isobutane , or pure isobutane, [ 31 ] called "Greenfreeze", but as a condition of the contract with Greenpeace ...
A science fair or engineering fair is an event hosted by a school that offers students the opportunity to experience the practices of science and engineering for themselves. In the United States, the Next Generation Science Standards makes experiencing the practices of science and engineering one of the three pillars of science education.
[1] [2] [3] The column was regarded for revealing the brass-tacks secrets of research and showing home-based experimenters how to make original discoveries using only inexpensive materials. Since its début in 1928, "The Amateur Scientist" was a primary resource for science fair projects.
