2,4-Dimethylpentane is an alkane with the chemical formula [(H 3 C) 2 CH] 2 CH 2. This colorless hydrocarbon is produced in large quantities in oil refineries. It results from the alkylation of isobutane by propylene. [1] Often referred to as "alkylate", it is blended with other gasoline components to give a high octane fuel.
The branched isomers are 2-methylbut-1-ene, 3-methylbut-1-ene (isopentene), and 2-methylbut-2-ene (isoamylene). Isoamylene is one of the three main byproducts of deep catalytic cracking (DCC), which is very similar to the operation of fluid catalytic cracking (FCC).
9 – MgBr with acetone to form 2,3-dimethyl-2-pentanol, then dehydrating this alcohol to form 2,3-dimethyl-2-pentene, and hydrogenating this product. [ 4 ] The isomer is present at about 2.4% by weight in the hydrocarbon mixture obtained by the condensation of methanol at 200 °C with a zinc iodide catalyst (the main component of the mixture ...
For 2,2-dimethylpentane they measured a density of 0.6737 at 20 °C with a rate of change Δd/ΔT of 0.000855. The density and boiling are the lowest of the isomers of heptane. The dielectric constant is 1.915, the lowest of the heptane isomers. The critical temperature is 247.7 °C and critical pressure 28.4 atmospheres.
A method to produce 3,3-dimethylpentane is to react tert-amyl chloride (CH 3 CH 2 (CH 3)C 2 Cl) with propionaldehyde producing 3,3-dimethylpentan-2-ol. This is then dehydrated to produce 3,3-dimethylpent-2-ene, which when hydrogenated produces some 3,3-dimethylpentane, but also 2,3-dimethylpentane.
