Crotononitrile (pract) Usage And Synthesis

Chemical Properties

CLEAR LIGHT YELLOW LIQUID

Definition

ChEBI: Crotononitrile is a nitrile.

General Description

Neurotoxic properties of crotononitrile have been investigated. Mechanism of the Baylis-Hillman reaction of crotononitrile and benzaldehyde in the presence of 1,4-diazabicyclo[2,2,2]octane (catalyst) has been investigated.

Purification Methods

Separate the mixture by preparative GLC on a column using 5% FFAP on Chromosorb G. [Lewis et al. J Am Chem Soc 108 2818 1986, Beilstein 2 IV 1507.]
