Isingeniso

I-propane kanye ne-propene ama-hydrocarbon asetshenziswa kakhulu ezimbonini zamakhemikhali ne-petroleum. Nakuba amagama azo zombili izinhlanganisela afana, kunomehluko obalulekile ekubunjweni kwawo kanye nezakhiwo. Kulesi sihloko sizokhuluma nge umehluko omkhulu phakathi kwe-propane ne-propene.

Ukwakheka

Ipropane iyi-alkane hydrocarbon enama-athomu ekhabhoni amathathu nama-athomu e-hydrogen ayisishiyagalombili, ifomula yamakhemikhali ye-propane yi-C3H8. Ngakolunye uhlangothi, i-propene iyi-alkene hydrocarbon enama-athomu e-carbon amathathu nama-athomu e-hydrogen ayisithupha, ifomula yayo yamakhemikhali yi-C3H6.

Izakhiwo zomzimba

Iphuzu elibilayo

I-Propane iyigesi engenambala futhi engenaphunga ezingeni lokushisa lasekamelweni, indawo yayo yokubilisa ingu -42 °C. Ngenxa yalokhu, ngokuvamile isetshenziswa njengophethiloli ezintweni zokushisisa nokupholisa. Ngakolunye uhlangothi, i-propene iyigesi engenambala futhi engenaphunga ekamelweni lokushisa, indawo yayo yokubilisa ingu -47,6 °C.

Ubuningi

I-propane iminyene kunomoya, okusho ukuthi iqoqana ezindaweni eziphansi futhi ingadala izingozi zokuqhuma. I-propene iminyene kancane kunomoya, okusho ukuthi ikhuphukela emoyeni ngokushesha futhi ingahlakazeka ngokuphephile uma kuvuza.

Ukusetshenziswa

  • I-propane isetshenziswa njengamafutha emakhaya nasemabhizinisini zokushisisa nokupheka ukudla.
  • I-Propene isetshenziselwa ukukhiqizwa kwamapulasitiki, imicu yokwenziwa, irabha yokwenziwa namanye amakhemikhali.
  • Okunye ukusetshenziswa kwe-propane kufana nophethiloli ezimotweni. igesi propano liquid (LPG), enganciphisa ukukhishwa kwegesi ebamba ukushisa kanye nokuncika kuwoyela.

Isiphetho

Kafushane, ngenkathi zombili izinhlanganisela zingama-hydrocarbon anama-athomu ekhabhoni amathathu, anomehluko obalulekile ekwakhekeni kwawo, izakhiwo ezingokomzimba, kanye nokusetshenziswa kwawo. I-propane isetshenziswa njengophethiloli nasembonini yegesi, kanti i-propene isetshenziswa ekukhiqizeni amapulasitiki namanye amakhemikhali.
