Yintoni i-Coupling ye-Ethylene Glycol kunye ne-Dimethyl Carbonate?

Ukudibanisa I-Ethylene Glycol kunye neDimethyl Carbonate
Le ndlela ingahlulwa ibe ngamanyathelo amabini aphambili: okokuqala, ikhabhoni diokside kunye ne-ethylene oxide zisabela phantsi kwe-catalyst ukwenza i-ethylene carbonate, ethi emva koko isabela kunye ne-methanol eyongezelelweyo ukwenza i-ethylene glycol kunye ne-dimethyl carbonate. Iingenelo zale ndlela ziquka:
Ukusetyenziswa kwe-CO₂, imveliso ephuma kwimveliso ye-ethylene oxide, ukunciphisa iindleko zezinto eziluhlaza kunye nokukhutshwa kwegesi ezibangela ubushushu.
I-ethylene carbonate isebenza kakuhle kakhulu, isebenza njengemveliso yeekhemikhali eguquguqukayo enokugcinwa nokuthuthwa ngokukhuselekileyo. Ingasetyenziswa njengesixhobo esiphakathi sokuvelisa i-ethylene glycol okanye ithengiswe ngokuthe ngqo njengemveliso egqityiweyo, ithintela ukusetyenziswa kwamandla aphezulu kunye nemiba yokungcola enxulumene namanzi njengezinto ezikrwada.
Imveliso ephumayo, i-dimethyl carbonate, inexabiso elongezelelekileyo kwaye sisixhobo esisetyenziswa kakhulu sekhemikhali.
Izinga lokusetyenziswa kweathomu lifikelela kwi-100%, libekwa njengenkqubo yokuvelisa ecocekileyo "engenakukhutshwa".
