ʻO ka propyne (methylacetylene) kahi alkyne me ke ʻano kemika CH3C≡CH. He ʻāpana ia o ke kinoea MAPD—me kāna isomer propadiene (allene), i hoʻohana mau ʻia i ka wili kinoea. ʻAʻole like me ka acetylene, hiki ke hoʻopili pono ʻia ka propyne.
Ua noiʻi nā hui ākea o ʻEulopa me ka hoʻohana ʻana i nā hydrocarbons māmā me ka oxygen wai, kahi hui pū ʻana o ka rocket propellant wai e ʻoi aku ka ʻona ma mua o ka MMH/NTO (monomethylhydrazine/nitrogen tetroxide). Ua hōʻike kā lākou noiʻi e ʻoi aku ka maikaʻi o ka propyne ma ke ʻano he wahie rocket no ka hana i manaʻo ʻia no nā hana orbital Earth haʻahaʻa. Ua hōʻea lākou i kēia hopena ma muli o kahi manaʻo kikoʻī i manaʻo ʻia e hiki i 370 s me ka oxygen e like me ka oxidizer, kahi kiʻekiʻe kiʻekiʻe a me ka nui o ka mana—a me ka pae hoʻolapalapa haʻahaʻa, kahi e maʻalahi ai ka mālama ʻana i ka kemika ma mua o nā wahie cryogenic pono e mālama ʻia ma kahi haʻahaʻa loa. nā mahana wela.
