General description

Carbon monoxide is a versatile building block used in carbonylation reactions and to prepare single-walled carbon nanotubes.

Application

Carbon monoxide can be used in the following applications:
  • Transition-metal-catalyzed carbonylation reactions.
  • Insertion of carbon monoxide in metal-carbon bonds during copolymerization reactions.
  • To grow single-wall carbon nanotubes (SWNT) via disproportionation reaction catalyzed by molybdenum particles.

Catalytic hydrogenation of carbon monoxide over transition metals catalysts to form hydrocarbons has been reported.

Packaging

Supplied in a carbon steel lecture bottle with a CGA180M/CGA110F needle valve installed.

Compatible with the following:
  • Aldrich® lecture-bottle station systems
  • Aldrich® lecture-bottle gas regulators
