alkane

 [al´kān]
a saturated hydrocarbon, i.e., one that has no carbon-carbon multiple bonds.

al·kane

(al'kān),
The general term for a saturated acyclic hydrocarbon; for example, propane, butane.

alkane

/al·kane/ (al´kān) any of a class of saturated hydrocarbons with a straight or branched chain structure, of the general formula CnH2n + 2.

alkane

a saturated aliphatic hydrocarbon containing no double or triple bonds in the carbon chain, such as propane. Also called paraffin.

alkane

Any of a number of saturated aliphatic (straight-chain) hydrocarbons of the methane series (methane, ethane, propane, butane, pentane, hexane, septane, octane, nonane, decane, etc.), in which the carbons are joined to other carbons by single bonds.

al·kane

(al'kān)
The general term for a saturated acyclic hydrocarbon (e.g., propane, butane).

alkane (alˑ·kānˈ),

n water-insoluble, saturated hydrocarbon compound, with the general chemical formula CnH2n+2. Hexane (C6H14) is used in the solvent extraction or enfleurage process. See also enfleurage.

alkane

a saturated hydrocarbon, i.e. one that has no carbon-carbon multiple bonds; formerly called paraffin.

Alkanes in the oils are, according to structure, divided into three classes: n-alkanes, branched alkanes and cycloalkanes, their distribution is shown in Figure 2.
Dry matter intake (DMI, kg DM/d) was estimated from the ratio of naturally occurring and dosed alkanes ([C.
Methane, ethane and propane, the major components in natural gas, belong to a class of molecules named alkanes that are the simplest hydrocarbons and one of the most abundant, cleanest sources of energy and materials.
The Korean researchers described detailed strategies for screening of enzymes associated with the production of fatty acids, engineering of enzymes and fatty acid biosynthetic pathways to concentrate carbon flux towards the short-chain fatty acid production, and also converting short-chain fatty acids to their corresponding alkanes (gasoline) by introducing a novel synthetic pathway and optimization of culture conditions.
The discovery - the first time such a process has been demonstrated to work - has previously been fraught with difficulties as alkanes have tended to either combust or over-dehydrogenate (when too much hydrogen is removed, leaving only soot, rather than useful chemicals), depending on whether oxygen is present.
Alkanes of intermediate chain length (C10-C24) are often degraded rapidly, while very long chain alkanes are increasingly resistant to microbial degradation [12].
The Cornell engineers are looking to prevent methane production by the microbes, and instead, to shape the bacterial communities to produce carboxylates, which are a precursor to the alkanes found in fuels.
Besides molecular adsorption of thiophene at low temperatures, the formation of alkanes, as desulfurization products, was detected at greater temperatures when keeping the catalysts in hydrogen ambient.
Mass transfer studies of carbon dioxide to liquid alkanes were carried out using the apparatus described in articles of our research group (Gomez-Daz and Navaza, 2003a,b) in previous works related to absorption processes.
