incazelo yomkhiqizo
I-Propyne (methylacetylene) iyi-alkyne enefomula yamakhemikhali ethi CH3C≡CH. Iyingxenye yegesi ye-MAPD—kanye ne-isomer propadiene (allene), eyayivame ukusetshenziswa ekushiseleni igesi. Ngokungafani ne-acetylene, i-propyne ingafinyezwa ngokuphepha.
Izinkampani zasemkhathini zaseYurophu zenze ucwaningo zisebenzisa ama-hydrocarbon alula anomoya-mpilo owuketshezi, inhlanganisela yerokhethi ewuketshezi esebenza kakhulu engase ibe nobuthi obuncane kune-MMH/NTO evame ukusetshenziswa (monomethylhydrazine/nitrogen tetroxide). Ucwaningo lwabo lubonise[ukucaphuna] ukuthi i-propyne ingaba nenzuzo enkulu njengophethiloli we-rocket womsebenzi wezandla ohloselwe ukusebenza okuphansi kwe-Earth orbital. Bafinyelele lesi siphetho ngokusekelwe kumfutho othize okulindeleke ukuthi ufinyelele ku-370 s nge-oxygen njenge-oxidizer, ukuminyana okuphezulu namandla okuminyana—kanye nendawo yokubilisa emaphakathi, okwenza ikhemikhali kube lula ukuyigcina kunezinto zokubasa ze-cryogenic okufanele zigcinwe ziphansi kakhulu. amazinga okushisa.
