Question: What alkane of six carbon atoms, also has the chemical formula CH and is part of the hydrocarbon based solvent mixture, Petroleum benzine?

<P0-S0> Hexane is an alkane of six carbon atoms, with the chemical formula CH. <SEP> <P1-S0>  The chemical composition of a petroleum distillate can also be modified to afford a solvent with reduced concentration of unsaturated hydrocarbons, "i.e." alkenes, by hydrotreating and/or reduced aromatics, "e.g." benzene, toluene xylene, by several dearomatization methods. <P1-S1>  In a document that attempts to draw more concise distinctions between hydrocarbon solvents, conservator Alan Phenix explains that the most important distinction amongst the various hydrocarbon solvents are their boiling/distillation ranges (and, by association, volatility, flash point etc.) and aromatic content. <P1-S2>  Given the toxicity/carcinogenicity of some aromatic hydrocarbons, most notably benzene, the aromatic content of petroleum distillate solvents, which would normally be in the 10-25% (w/w) range for most petroleum fractions, can be advantageously reduced when their special solvation properties are not required and a less odorous, lower toxicity solvent is desired, especially when present in consumer products. <P1-S3>  Phenix further points out that "To all intents and purposes petroleum benzine appears synonymous with petroleum spirit." <P1-S4>  Petroleum spirit is generally considered to be the fractions between the very lightest hydrocarbons, petroleum ether, and the heavier distillates, mineral spirits. <P1-S5>  For example, petroleum benzine with a boiling range of 36 - 83 °C sold by EMD Millipore under CAS-No. <P1-S6> Petroleum benzine is a hydrocarbon based solvent mixture that is classified by its physical properties (e.g. boiling point, vapor pressure) rather than a specific chemical composition, often obfuscating distinction within the long list of petroleum distillate solvent mixtures: mineral spirits, naphtha, white spirits, petroleum spirits, turps substitute, mineral turpentine, petroleum benzine, petroleum ether, ligroin, and Stoddard Solvent. <P1-S7>  64742-49-0 is identified in the product MSDS as hydrotreated light petroleum distillates comprising ≥ 90% C5-C7 hydrocarbons, n-alkanes, isoalkanes, and < 5% n-hexane, while Santa Cruz Biotechnology sells a petroleum ether product under the same CAS-No. <P1-S8>  Fisher Scientific offers a product ‘Benzine (Petroleum Naphtha)' that retails for a high price that would suggest it is a speciality product but in fact conforms to Marathon Petroleum's 'VM&P Naphtha' (Varnish Makers & Painters’ Naphtha) found widely distributed in many hardware stores in North America. <SEP> <P2-S0> Cycloundecane is a saturated cyclic organic compound with eleven carbon atoms forming a ring. <P2-S1>  It is classed as an alkane because it has only carbon and hydrogen and these elements are configured with C–H and C–C such that there is a chain of carbon atoms with hydrogens attached to them. <P2-S2>  For each of the carbon atoms in the chain there is a pair of hydrogen atoms such that the chemical formula is CH. <P2-S3>  The compound is stable, but it burns with sufficient ignition heat. <SEP> <P3-S0> Hexadecane (also called cetane) is an alkane hydrocarbon with the chemical formula CH. <P3-S1>  Hexadecane consists of a chain of 16 carbon atoms, with three hydrogen atoms bonded to the two end carbon atoms, and two hydrogens bonded to each of the 14 other carbon atoms.
