Ukuhlanganiswa kwe I-Ethylene Glycol kanye ne-Dimethyl Carbonate
Le ndlela ingahlukaniswa ngezinyathelo ezimbili eziyinhloko: okokuqala, i-carbon dioxide kanye ne-ethylene oxide kusabela ngaphansi kwe-catalyst ukukhiqiza i-ethylene carbonate, bese isabela ne-methanol eyengeziwe ukwakha i-ethylene glycol kanye ne-dimethyl carbonate. Izinzuzo zale ndlela zifaka:
Ukusetshenziswa kwe-CO₂, umkhiqizo ophuma eceleni wokukhiqizwa kwe-ethylene oxide, ukunciphisa izindleko zezinto zokusetshenziswa kanye nokukhishwa kwamagesi okushisa ukushisa.
I-ethylene carbonate isebenza kahle kakhulu, isebenza njengomkhiqizo wamakhemikhali oguquguqukayo onesitoreji esiphephile kanye nokuthuthwa. Ingasetshenziswa njengendlela yokuxhumana yokukhiqizwa kwe-ethylene glycol noma ithengiswe ngqo njengomkhiqizo oqediwe, igwema ukusetshenziswa kwamandla aphezulu kanye nezinkinga zokungcola ezihambisana namanzi njengezinto zokusetshenziswa.
Umkhiqizo olandelanayo, i-dimethyl carbonate, unenani eliphezulu elengeziwe futhi uyinto eluhlaza eyisisekelo yamakhemikhali esetshenziswa kabanzi.
Izinga lokusetshenziswa kwe-athomu lifinyelela ku-100%, lihlukaniswe njengenqubo yokukhiqiza ehlanzekile "engakhiphi lutho".
