Umsebenzi ophambili kunye neempawu zesakhiwo:

Amacandelo aphambili esicatshulwa yi-CH; Cls, ioli emhlophe kunye namanzi okulandelela.ukuthatha

inzuzo yamanqaku abilayo ahlukeneyo ezinto ezintathu, isicatshulwa siqhutywa

ngokulandelelanayo ngokulandelelana kwamanyathelo, afana ne-distillation yokuqala, i-atmospheric

i-distillation, i-vacuum gas extraction, i-CH: i-Cla kunye nokuhluzwa kweoli emhlophe.ukutsalwa

isisombululo sahlulwa kwaye sahlanjululwa ukubuyisela i-CH;Cl;(ubunyulu> 99.97%) kunye neoli emhlophe

(ubunyulu> 99.97%) ukuhlangabezana neemfuno zokusetyenziswa kwakhona kumgca wemveliso kunye nokunciphisa

ukusetyenziswa kwezinto zenkqubo yemveliso, Nciphisa iindleko zemveliso ye

ifilimu yokwahlula.
