Ukusebenza okuyinhloko kanye nezici zesakhiwo:

Izingxenye eziyinhloko zokukhishwa yi-CH;Cls, amafutha amhlophe kanye namanzi okulandelela.ukuthatha

inzuzo yamaphuzu abilayo ahlukene wezinto ezintathu, i-extract iqhutshwa

ngokulandelana ngochungechunge lwezinyathelo, ezifana ne-distillation yokuqala, i-atmospheric

i-distillation, i-vacuum gas extraction, i-CH: i-Cla kanye nokuhlunga kwamafutha amhlophe.ukukhishwa

isisombululo sahlukaniswa futhi sahlanzwa ukuze kubuyiselwe i-CH;Cl;(ubumsulwa> 99.97%) namafutha amhlophe

(ubumsulwa>99.97%) ukuze uhlangabezane nezimfuneko zokuphinda usetshenziswe kulayini wokukhiqiza nokunciphisa

ukusetshenziswa kwempahla yohlelo lokukhiqiza, Yehlisa izindleko zokukhiqiza

ifilimu yesihlukanisi.
