The homologous series of straight-chained alkanes begins methane ( CH 4 ), ethane ( C 2 H 6 ), propane ( C 3 H 8 ), butane ( C 4 H 10 ), and pentane ( C 5 H 12 ).
42.
DAO from propane de-asphalting has the highest quality but lowest yield, whereas using pentane may double or triple the yield from a heavy feed, but at the expense of contamination by metals and carbon residues that shorten the life of downstream cracking catalysts.
43.
That sour gas is sent to the refinery's central gas processing plant for removal of the hydrogen sulfide in the refinery's main amine gas treating unit and through a series of distillation towers for recovery of propane, butane and pentane or heavier components.
44.
Figure 2 is an example of a generalized compressibility factor graph derived from hundreds of experimental PVT data points of 10 pure gases, namely methane, ethane, ethylene, propane, n-butane, i-pentane, n-hexane, nitrogen, carbon dioxide and steam.
45.
Finally, lighter fluid itself is made up of various volatile hydrocarbons, including, but not limited to, Light aliphatic hydrocarbons, such as Butane, pentane, hexane, etc ., Benzene ( hopefully not much, in the developed world ), perhaps some toluene or phenol.
46.
The melting point of neopentane ( " 16.6 �C ), on the other hand, is 140 degrees higher than that of isopentane ( " 159.9 �C ) and 110 degrees higher than that of " n "-pentane ( " 129.8 �C ).
47.
In a lab, the determination of AOX parameter consists of adsorption of organic halides from the sample on to an activated carbon . or granular Alternatively, the chlorinated compounds in the sample can be determined by using pentane extraction followed by capillary high performance liquid chromatography ( HPLC ) could also be implemented to quantify AOX levels.
48.
Cycloalkanes are named as per their acyclic counterparts with respect to the number of carbon atoms in their backbones, e . g ., cyclopentane ( C 5 H 10 ) is a cycloalkane with 5 carbon atoms just like pentane ( C 5 H 12 ), but they are joined up in a five-membered ring.
49.
*To get an intuitive grasp, consider that Tungsten hexafluoride is one of the heaviest gasses at room temperature, and while pentane boils between 9 and 36 centigrade, hexane is a liquid at room temperature .

This transformation was achieved via the thermoloysis of Cp * W ( NO ) ( ? 3-allyl ) ( CH 2 CMe 3 ) in pentane at room temperature, resulting in elimination of neopentane by a pseudo-first-order process, generating an undetectable electronically and sterically unsaturated 18-electron complex possessing an " n "-pentyl ligand.
