Ngokuqinisekileyo. Irhasi yepetroleum enyibilikisiweyo, ubukhulu becala yenziwe ngepropane kunye nebutane, ikwaqulathe imiyinge emincinci yeegesi ezifana ne-ethane, propene, kunye nepentane.
Kuphuhliso lwakutsha nje, ipropane yokugcina iye yatshintshela kwiisilinda zentsimbi ezikhethekileyo, eyilwe ngeevalvu ezinokusebenza kuphela kusetyenziswa isitshixo esinehexagonal sangaphakathi esisodwa. Olu tshintsho lujongene nokuguquguquka okuphezulu kunye noxinzelelo lwepropane, kugxininisa imfuneko yala masilinda akhethekileyo ukuqinisekisa ukugcinwa okukhuselekileyo kunye nokuzaliswa kwakhona okusebenzayo.
