General description

Propyne (methylacetylene) is commonly used in gas welding.

Application

Propyne (CH3C≡CH) can be used:
  • As a fuel for stoichiometric low-pressure flat-flames in isomer-specific combustion studies.
  • In the synthesis of polycyclic aromatic hydrocarbons under various reaction conditions.
  • In the synthesis of phenylacetylenes.
  • In the selective synthesis of propene by catalytic hydrogenation using Pt/Al2O3 catalyst.
