Propyn

Propyne (methylacetylene) is an alkyne with the chemical formula C H 3 C≡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.

Propyne (methylacetylene) is commonly used in gas welding. Propyn är en, ofta oönskad, biprodukt som bildas när man krackar propan för att producera propen. From Wikipedia, the free encyclopedia Propargyl alcohol, or 2-propyn-1-ol, is an organic compound with the formula C 3 H 4 O. It is the simplest stable alcohol containing an alkyne functional group. Propargyl alcohol is a colorless viscous liquid that is miscible with water and most polar organic solvents.
