2,3-DIMETHYL-1,3-BUTADIENE Chemical Properties,Usage,Production

Chemical Properties

Clear colorless liquid

Uses

2,3-Dimethyl-1,3-butadiene undergoes Diels Alder cycloaddition reaction and it also participates in polymerization reactions. It is also involved in manufacturing of synthetic rubber.

General Description

2,3-Dimethyl-1,3-butadiene (DMBD) is a conjugated diene. It undergoes Diels Alder cycloaddition reaction with 2-thio-3-chloroacrylamides under thermal, catalytic and microwave conditions. It undergoes thermal [4+2] cycloaddition reaction with 3-acetyl-, 3-carbamoyl and 3-ethoxycarbonylcoumarins under solvent free conditions. DMBD participates in polymerization reactions in the presence of iron dichloride complexes based catalysts.

Purification Methods

Distil it from NaBH4, and purify it by zone melting. [Beilstein 1 IV 1023.]
