  2. Isobutylene - Wikipedia

    en.wikipedia.org/wiki/Isobutylene

    Isobutylene (or 2-methylpropene) is a hydrocarbon with the chemical formula (CH 3) 2 C=CH 2. It is a four-carbon branched alkene (olefin), one of the four isomers of butylene . It is a colorless flammable gas, and is of considerable industrial value.

  3. 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.

    en.wikipedia.org/wiki/Isoprenol

    Isoprenol, also known as 3-methylbut-3-en-1-ol, is a hemiterpene alcohol. It is produced industrially as an intermediate to 3-methylbut-2-en-1-ol (prenol): global production in 2001 can be estimated as 6–13 thousand tons.

    That implies a stabilization energy of 3.5 kcal/mol. [25] Similarly, the hydrogenation of the terminal double bond of 1,4-pentadiene releases 30.1 kcal/mol of heat, while hydrogenation of the terminal double bond of conjugated (E)-1,3-pentadiene releases only 26.5 kcal/mol, implying a very similar value of 3.6 kcal/mol for the stabilization ...

  7. 2-Methyl-2-butene - Wikipedia

    en.wikipedia.org/wiki/2-Methyl-2-butene

    2-Methyl-2-butene, 2m2b, 2-methylbut-2-ene, beta-isoamylene, or Trimmethylethylene is an alkene hydrocarbon with the molecular formula C 5 H 10. Used as a free radical scavenger in trichloromethane (chloroform) and dichloromethane (methylene chloride).

  8. Dimethylbutadiene - Wikipedia

    en.wikipedia.org/wiki/Dimethylbutadiene

    Dimethylbutadiene readily undergoes Diels-Alder reactions and reacts faster than 1,3-butadiene. Its effectiveness in this reaction is attributed to the stabilization of the cis-conformation owing to the influence of the methyl groups on the C2 and C3 positions. Diels-Alder reaction using 2,3-dimethyl-1,3-butadiene and N-ethylmaleimide

  9. 1-Butene - Wikipedia

    en.wikipedia.org/wiki/1-Butene

    1-Butene (IUPAC name: But-1-ene, also known as 1-butylene) is the organic compound with the formula CH 3 CH 2 CH=CH 2. It is a colorless gas. But-1-ene is an alkene easily condensed to give a colorless liquid. It is classified as a linear alpha-olefin (terminal alkene). [2] It is one of the isomers of butene (butylene). It is a precursor to ...
