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. Visa mer Propyne exists in equilibrium with propadiene, the mixture of propyne and propadiene being called MAPD: The coefficient of equilibrium Keq is 0.22 at 270 °C or 0.1 at 5 °C. MAPD is produced as a side product, … Visa mer European space companies have researched using light hydrocarbons with liquid oxygen, a relatively high performing liquid rocket propellant combination that would also be less toxic than the commonly used MMH/NTO (monomethylhydrazine Visa mer 1. ^ "Prop-1-yne" mistake fixed in the errata Archived 2024-08-01 at the Wayback Machine.
