CIS-2-HEXENE Usage And Synthesis

Chemical Properties

Clear colorless liquid

Uses

trans-2-Hexene is used as a co monomer in the production of polyethylene. The use of trans-2-hexene, which is derived from 3-hexyne using sodium in liquid ammonia.

Definition

ChEBI: 2E-hexene is a hydrocarbon.

General Description

trans-2-hexene is formed by the double bond shift and cis-trans isomerization which can be studied using microreactor-GLC techniques.

Purification Methods

Purify it as for 1-hexene above. [Beilstein 1 IV 834.]
