Propyne (methylacetylene) is an alkyne with the chemical formula CH3C≡CH. It is a component of MAPD gas —along with its isomer propadiene (allene), which was commonly used in gas welding. Unlike acetylene, propyne can be safely condensed. [3] Propyne exists in equilibrium with propadiene, the mixture of propyne and propadiene being called MAPD:

Insoluble in water, soluble in ethanol, chloroform and benzene. Moderately toxic by inhalation. Used as a specialty fuel. Denser than air. Vapors may ignite at distant sources of ignition and flash back. Propyne is an alkyne, a terminal acetylenic compound and a gas molecular entity. prop-1-yne. InChI=1S/C3H4/c1-3-2/h1H,2H3.
