1,5-hexadiene is an organic chemical compound with the empirical formula C 6 H 10 . It belongs to the group of dienes .
Extraction and presentation
1,5-Hexadiene can be produced from the gas phase reaction between propene and 3-bromopropene . Another possibility is the oxidative gas phase reaction between two molecules of propene with hydrogen peroxide .
properties
It is a colorless liquid that solidifies at −141 ° C and boils at 60 ° C. The flash point is −46 ° C. In the range of 2 to 6.1 percent by volume of the gas in air, explosive mixtures form.
use
1,5-Hexadiene can be used to synthesize other hexane derivatives . This includes, for example, the synthesis of 1,6-hexanediol , which can be produced from 1,5-hexadiene by hydroboration .
