Propyne (methylacetylene) ndi alkyne yokhala ndi formula yamankhwala CH3C≡CH. Ndi gawo la mpweya wa MAPD-pamodzi ndi isomer propadiene (allene), yomwe imagwiritsidwa ntchito kwambiri pakuwotcherera gasi. Mosiyana ndi acetylene, propyne imatha kusungidwa bwino.
Makampani opanga zakuthambo ku Europe afufuza pogwiritsa ntchito ma hydrocarbon owala okhala ndi okosijeni wamadzimadzi, kuphatikiza kwa rocket yamadzi yomwe imagwira ntchito kwambiri yomwe ingakhalenso yapoizoni yochepa kuposa yomwe imagwiritsidwa ntchito nthawi zambiri ya MMH/NTO (monomethylhydrazine/nitrogen tetroxide). Kafukufuku wawo adawonetsa [zofunikira] kuti propyne ingakhale yopindulitsa kwambiri ngati mafuta a rocket opangira zida zogwirira ntchito zotsika za Earth orbital. Iwo anafika pa mfundo imeneyi potengera kukhudzika kwapadera komwe kumayembekezereka kufika ku 370 s ndi okosijeni monga oxidizer, kachulukidwe kakang'ono komanso kachulukidwe ka mphamvu - komanso kuwira pang'ono, komwe kumapangitsa kuti mankhwala azikhala osavuta kusunga kuposa mafuta a cryogenic omwe amayenera kukhala otsika kwambiri. kutentha.
