whakaahuatanga hua
Ko te Propyne (methylacetylene) he alkyne me te tauira matū CH3C≡CH. He wahanga o te hau MAPD—me tana isomer propadiene (allene), i whakamahia i te nuinga o te waa ki te whakahiato hau. Kaore i rite ki te acetylene, ka taea e te propyne te noho humarie.
Kua rangahaua e nga kamupene mokowhiti a te Pakeha te whakamahi i te waiwaro marama me te hāora wai, he whakakotahitanga toka toka wai tino kaha ka iti ake te paitini i te MMH/NTO (monomethylhydrazine/nitrogen tetroxide). I whakaatuhia e ta raatau rangahau he tino painga te propyne hei wahie toka mo nga mahi toi mo nga mahi orbital whenua iti. I tutuki i a raatau tenei whakatau i runga i te hiahia kia eke ki te 370 s me te hāora hei oxidizer, he kiato teitei me te kiato mana—me te ira koropuputanga ngawari, he maamaa ake te penapena matū i nga kora cryogenic me pupuri i te iti rawa. pāmahana.
