cov khoom piav qhia
Propyne (methylacetylene) yog ib qho alkyne nrog cov tshuaj formula CH3C≡CH. Nws yog ib feem ntawm MAPD roj-nrog rau nws cov isomer propadiene (allene), uas feem ntau siv hauv cov roj vuam. Tsis zoo li acetylene, propyne tuaj yeem ua rau muaj kev nyab xeeb.
Cov tuam txhab nyob sab Europe tau tshawb fawb siv lub teeb hydrocarbons nrog cov kua oxygen, qhov ua tau zoo ntawm cov kua foob pob hluav taws ua ke uas tseem yuav muaj tshuaj lom tsawg dua li MMH / NTO (monomethylhydrazine / nitrogen tetroxide). Lawv cov kev tshawb fawb pom tau tias [tsim xav tau] tias propyne yuav muaj txiaj ntsig zoo li lub foob pob hluav taws roj rau cov khoom siv tes ua rau lub ntiaj teb qis orbital ua haujlwm. Lawv tau mus txog qhov xaus no raws li cov impleulse yuav tsum tau mus txog 370 s nrog oxygen, uas ua rau cov tshuaj lom neeg yooj yim dua li cryogenic ruels uas yuav tsum tau ceev cia ntawm tsawg kawg kub.
