Figure 6. Comparison of observed and calculated vibrational spectra for a butane monolayer (19). (Topi Observed spectrum for monolayer butane adsorbed on a graphitized carbon powder at 80 K. The background inelastic scattering from the substrate has been subtracted, (a) Calculated spectrum for the butane molecule adsorbed with its carbon skeleton parallel to the graphite layers and the bottom layer of four hydrogen atoms bonded to the surface with force constants listed in Table I. (b) Same orientation but only the carbon atoms are bonded to the surface with a force constant of 0.12 mdyn/A. (Bottom) Butane carbon plane perpendicular to the graphite layers and the bottom layer of four hydrogen atoms bonded to the surface with the same force constants as in the parallel orientation.

In these model calculations, the best fit to the observed spectrum was obtained with the butane carbon plane parallel to the surface with bonds to the bottom layer of hydrogens (Fig. 6(a)). The agreement worsened when carbon-substrate bonds were included in this orientation and became quite bad when the hydrogen-substrate bonds were neglected entirely (Fig. 6(b)). With the carbon plane perpendicular to the surface (Fig. 6(c)), no combination of force constants yielded as good a fit as in the plane-parallel configuration. 

Increased ethylene concentration or temperature produces more oils, butanes, carbon, etc., while more water dilutes the phosphoric acid and reduces its activity. Exact operating conditions will vary with the condition of the catalyst. 

This is probably because 0 atoms produced in primary process (45) react much more rapidly with C2H6 than with N20. Several products are formed including ethylene, butane, carbon monoxide, hydrogen, methane, and probably ethanol and acetaldehyde. More ethylene is formed than one would expect from the amount of butane. It was found that 0 atoms react rapidly with ethylene, which is one of the photolytic products. The reaction-rate constant of O atoms with ethylene is estimated to be about 330 times as rapid as that with ethane.82 Complete elucidation of the mechanism of O-atom reaction with ethane is complicated because of the rapid reaction of O atoms with one or more of the products. 

Ferrioxamines, typical constituents of culture broths of Actinomycetes, occm as both hnear and cychc compounds containing l-amino-5-hydroxyaminopentane (A-hydroxycadaverine) and succinic acid as building blocks (Figure 1(c)). A cyclic trimer of succinyl-(A-hydroxycadaverine), is named ferrioxamine E. In some cases the pentane moiety is replaced by a butane carbon skeleton (putrescine). The most prominent representative of this siderophore family, desferrioxamine B (Figure 1), has become the drug of choice for the treatment of transfusional iron overload (Section 6.2). The crystal structure of ferric ferrioxamine B has been published recently. Certain derivatives of the ferrioxamines display antibiotic activity and therefore have been designated as ferrimycins. ...

The hydrate forming gases include light alkanes (methane to n-butane), carbon dioxide, hydrogen sulfide, nitrogen, and oxygen. 

The structural features of the isobutane molecule are otherwise essentially the same as those of n-butane carbon-carbon bond length 1.54 A, carbon-hydrogen bond length 1.10 A, bond angles close to 109.5°, and staggered orientation about the carbon-carbon bonds.

If you think that the structures represent two different substances, you are correct. The structure on the left represents butane, and the structure on the right represents a branched-chain alkane known as isobutane—a substance whose chemical and physical properties are different from those of butane. Carbon atoms can bond to one, two, three, or even four other carbon atoms. This property makes possible a variety of branched-chain alkanes. 

Natural gas (8006-14-2) is the gaseous component of petroleum. It is mostly methane with some ethane and smaller quantities of propane, butane, carbon dioxide, hydrogen sulphide, nitrogen, helium, and other gases. It is distributed in commerce as compressed or liquefied natural gas (LNG) for fuel and other purposes.

Gas hydrates (clathrates) may technically be considered as an alternative form of ice that has the ability to entrap relatively large volumes of gas within cavities in the hydrate crystal matrix. The entrapped guest molecules (gas) stabilize the structure by means of van der Waals interactions, and combinations of the different unit cells give rise to structures I, II (175-177), and H (178). The most common gas to form gas hydrates is methane, but ethane, propane, butane, carbon dioxide, nitrogen, and many other types of gases may also give rise to gas hydrates.

Sources of gaseous hydrocarbons are the natural gas wells and chemical manufacturing processes. Major constituents of natural gas is primarily composed of methane (over 90%) and smaller compositions of other gases like ethane, propane, butane, carbon dioxide, hydrogen, nitrogen, and oxygen.
