    en.wikipedia.org/wiki/2-Methylpentane

    As of early 1990s, it was present in American [4] and European [5] gasoline in small amounts, and by 2011 its share in US gas varied between 2 and 8%. [6] Using a quantitative structure-activity relationship (QSAR) prediction model, 2-Methylpentane has a research octane number (RON) of 75, motor octane number (MON) of 77, and cetane number (CN ...

  4. Azeotrope tables - Wikipedia

    en.wikipedia.org/wiki/Azeotrope_tables

    This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

  5. Methylpentene - Wikipedia

    en.wikipedia.org/wiki/Methylpentene

    Methylpentene is an alkene with a molecular formula C 6 H 12.The prefix "methyl-" is derived from the fact that there is a methyl(CH 3) branch, the word root "-pent-" is derived from the fact that there are 5 carbon atoms in the parent chain, while the "-ene" suffix denotes that there is a double bond present, as per IUPAC nomenclature. [1]

  6. Boiling-point elevation - Wikipedia

    en.wikipedia.org/wiki/Boiling-point_elevation

    The boiling point elevation happens both when the solute is an electrolyte, such as various salts, and a nonelectrolyte. In thermodynamic terms, the origin of the boiling point elevation is entropic and can be explained in terms of the vapor pressure or chemical potential of the solvent. In both cases, the explanation depends on the fact that ...

  7. Ebullioscope - Wikipedia

    en.wikipedia.org/wiki/Ebullioscope

    The advantage of this method was that the boiling point is relatively insensitive to other components such as sugars. Older alcoholimeters were based on measuring the density, which is more sensitive to the presence of other solutes. [1] [2] A famous ebullioscope variant was built by Pierre Marie Edouard Malligand, patented in 1876. [3]

  8. List of physical constants - Wikipedia

    en.wikipedia.org/wiki/List_of_physical_constants

    The constants listed here are known values of physical constants expressed in SI units; that is, physical quantities that are generally believed to be universal in nature and thus are independent of the unit system in which they are measured. Many of these are redundant, in the sense that they obey a known relationship with other physical ...

  9. 2-Methyl-1-pentanol - Wikipedia

    en.wikipedia.org/wiki/2-Methyl-1-pentanol

    2-Methyl-1-pentanol (IUPAC name: 2-methylpentan-1-ol) is an organic chemical compound. It is used as a solvent and an intermediate in the manufacture of other chemicals. [ 2 ] Due to its low solubility in water it has recently been suggested as a solvent in liquid–liquid extraction of ethanol from fermented feedstocks.
