  • ethane
  • The smallest alkane with such a chemical bond, ethane, exists as an infinite number of conformations with respect to rotation around the C-C bond. (wikipedia.org)
  • For example, the conversion of n-hexane to n-decane and ethane has been proposed for the purpose of improving the overall yield of diesel grade n-alkane (C9H20 to C19H40) from Fischer-Tropsch reactors, which convert syngas to a broad range of n-alkanes. (wikipedia.org)
  • cyclohexane
  • The six-membered ring of the alkane, cyclohexane, has the 'chair' as its preferred conformation and through proton NMR it would be expected that the produced spectrum would show the different sorts of protons (axial and equatorial) resonating at different frequencies, and so two signals would be seen, due to the protons being in slightly different chemical environments. (wikipedia.org)
  • bonds
  • The selective activation and functionalization of alkane C-H bonds was reported using a tungsten complex outfitted with pentamethylcyclopentadienyl, nitrosyl, allyl and neopentyl ligands, Cp*W(NO)(η3-allyl)(CH2CMe3). (wikipedia.org)
  • chromatography
  • Mixtures of the normal alkanes are used as boiling point standards for simulated distillation by gas chromatography. (wikipedia.org)
  • In preparative chromatography, concentration of a large volume of hexanes can result in a sample that is appreciably contaminated by alkanes. (wikipedia.org)
  • catalysts
  • Because the iridium-based catalysts show selectivity for the termini of n-alkanes, these systems have the unique ability to effect alkane metathesis with some selectivity for product molecular weight. (wikipedia.org)
  • More particularly, novel caged, or encapsulated, metal oxide catalysts and processes utilizing such catalysts to convert alkanes to alcohols and/or ethers and to convert alcohols and/or ethers to alkenes are. (google.com)
  • structural
  • In the present paper we investigate whether the HPLC parameters of alkanes could be predicted from the QSPR-type models using the Wiener number as a structural descriptor. (springer.com)
  • Tetracosane, also called tetrakosane, is an alkane hydrocarbon with the structural formula H(CH2)24H. (wikipedia.org)
  • derivatives
  • According to Georgia State University's HyperPhysics, alkane derivatives are also used in paints, cosmetics and detergents. (reference.com)
  • wherein
  • 6. The process of claim 1 wherein the one or more alkane halides is methylchloride, methylbromide, or a mixture thereof. (google.com)
  • reaction
  • Alkane metathesis is a class of chemical reaction in which an alkane is rearranged to give a longer or shorter alkane product. (wikipedia.org)
  • Abstract "Mechanism and poisoning of the molecular redistribution reaction of alkanes with a dual-functional catalyst system. (wikipedia.org)
  • Yes Chromium oxide reaction is valid for all alkanes. (physicsforums.com)
  • In the latter example, the reaction is presumed to proceed via the oxidative addition of alkane to a 16-electron iridium(I) intermediate, Cp*Ir(CO), formed by irradiation of Cp*Ir(CO)2. (wikipedia.org)
  • chemical
  • In enzymology, an alkane 1-monooxygenase (EC 1.14.15.3) is an enzyme that catalyzes the chemical reactions an alkane + reduced rubredoxin + O2 ⇌ {\displaystyle \rightleftharpoons } a primary alcohol + oxidized rubredoxin + H2O. (wikipedia.org)
  • lower
  • The boiling points of the various hexanes are somewhat similar and, as for other alkanes, are generally lower for the more branched forms. (wikipedia.org)
  • melting points
  • However the higher melting points of these alkanes can cause problems at low temperatures and in polar regions, where the fuel becomes too thick to flow correctly. (wikipedia.org)
  • example
  • For example, if A is formed twice as fast as B, the A:B product ratio will be 2 Consider chlorination of the alkane below at 35 °C 1. (chegg.com)
  • In one example involving this system, the alkane pentane is selectively converted to the halocarbon 1-iodopentane. (wikipedia.org)
  • metal
  • Metathesis of Alkanes Catalyzed by Silica-Supported Transition Metal Hydrides. (wikipedia.org)
  • Reactions classified by the term typically involve the hydrocarbon first to react with a metal catalyst to create an organometallic complex in which the hydrocarbon is coordinated to the inner-sphere of a metal, either via an intermediate "alkane or arene complex" or as a transition state leading to a "M−C" intermediate.
