butane

 [bu´tān]
an aliphatic hydrocarbon, C4H10, from petroleum; used in pharmacy as an aerosol propellant.

bu·tane

(byū'tān),
C4H10; a gaseous hydrocarbon present in natural gas; two isomers are known, both of which are anesthetically active: N-butane is CH3(CH2)2CH3 and isobutane is CH3CH(CH3)CH3 (or 2-methylpropane).

L]-values for pure methane, the USC mechanisms have only been used to calculate the relative influence of admixing propane or n-butane.
Besides this, mixtures with considerably low methane numbers could be calculated by using high amounts of n-butane, for example 40 mol-% is equal to a methane number of 32.
The denatured ethanol/CBOB blends are shown together, while the blends with additional n-butane are shown individually.
As it can be seen, following an isobaric density curve, the gradients of the density of propene (Figure 5) have their maximum between ~100[degrees]C and 150[degrees]C dependent on the pressure, while the density of n-butane (Figure 7) rapidly drops between 152[degrees]C and 180[degrees]C.
As with AVL, the large spread is partially caused by not taking into account the difference between i-butane and n-butane.
