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.]
