3 Ethylpentan is a chemical compound selected from the group consisting of aliphatic saturated hydrocarbons. It is one of nine constitutional isomers of heptane.

Production and representation

3- Ethylpentan is found in petroleum. The compound can be obtained in small amounts by the isomerization of n-heptane. As early as 1927, a laboratory synthesis has been described, wherein the Grignard compound is reacted with ethyl bromide in 3-pentanone. The resulting 3-ethyl -3-pentanol is dehydrated for 3 -ethyl-2 -pentene, and then hydrogenated to the 3- by Nickelkatalysor Ethylpentan.
