Propyne (methylacetylene) is commonly used in gas welding.

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.

Supplied in a Sure/Pac^™ cylinder and has a brass needle valve with a male 1/4" NPTF outlet thread installed. Before using the cylinder, ensure that the valve is closed, then remove the galvanized steel hex cap that seals the outlet valve.
