  2. 3-Methylhexane - Wikipedia

    en.wikipedia.org/wiki/3-Methylhexane

    3-Methylhexane is a branched hydrocarbon with two enantiomers. [2] It is one of the isomers of heptane. The molecule is chiral, and is one of the two isomers of heptane to have this property, the other being its structural isomer 2,3-dimethylpentane. The enantiomers are (R)-3-methylhexane [3] and (S)-3-methylhexane. [4]

  3. Transhalogenation - Wikipedia

    en.wikipedia.org/wiki/Transhalogenation

    C 3 H 5-Cl + NaF → R-F + NaCl This kind of reaction is called Finkelstein reaction . [ 2 ] However, it is also possible, for example, to produce phosphorus fluoride compounds by transhalogenating chlorine, bromine or iodine bound to phosphorus with a metal fluoride.

  4. Haloform reaction - Wikipedia

    en.wikipedia.org/wiki/Haloform_reaction

    In chemistry, the haloform reaction (also referred to as the Lieben haloform reaction) is a chemical reaction in which a haloform (CHX 3, where X is a halogen) is produced by the exhaustive halogenation of an acetyl group (R−C(=O)CH 3, where R can be either a hydrogen atom, an alkyl or an aryl group), in the presence of a base.

  5. Dehalogenation - Wikipedia

    en.wikipedia.org/wiki/Dehalogenation

    In organic chemistry, dehalogenation is a set of chemical reactions that involve the cleavage of carbon-halogen bonds; as such, it is the inverse reaction of halogenation. Dehalogenations come in many varieties, including defluorination (removal of fluorine ), dechlorination (removal of chlorine ), debromination (removal of bromine ), and ...

  6. Hydrohalogenation - Wikipedia

    en.wikipedia.org/wiki/Hydrohalogenation

    By reaction with tertiary amines, long-chain alkyl bromides such as 1-bromododecane, give quaternary ammonium salts, which are used as phase transfer catalysts. [ 9 ] With Michael acceptors the addition is also anti-Markovnikov because now a nucleophilic X − reacts in a nucleophilic conjugate addition for example in the reaction of HCl with ...

  7. MOSCED - Wikipedia

    en.wikipedia.org/wiki/MOSCED

    In addition to infinite dilution, MOSCED can be used to parameterize excess Gibbs Free Energy model such as NRTL, WILSON, Mod-UNIFAC to map out Vapor Liquid Equilibria of mixture. This was demonstrated briefly by Schriber and Eckert [ 3 ] using infinite dilution data to parameterize WILSON equation.

  9. Stefan problem - Wikipedia

    en.wikipedia.org/wiki/Stefan_problem

    Apart from modelling melting of solids, Stefan problem is also used as a model for the asymptotic behaviour (in time) of more complex problems. For example, Pego [10] uses matched asymptotic expansions to prove that Cahn-Hilliard solutions for phase separation problems behave as solutions to a non-linear Stefan problem at an intermediate time ...
