Ukuguqulwa kwepropylene kwipropylene oxide yinkqubo enzima efuna ukuqonda ngokucokisekileyo iindlela zokuphendula iikhemikhali ezibandakanyekayo. Eli nqaku lihlalutya kwiindlela ezahlukeneyo kunye neemeko zokusabela ezifunekayo ekudibaneni kwepropylene oxide kwipropylene.

Eyona ndlela iqhelekileyo yokuveliswa kwepropylene oxide ngokusebenzisa i-oxidation yepropylene kunye ne-molecular oxygen phambi kokuba kubekho i-catalyst. Indlela yokusabela ibandakanya ukubunjwa kwe-peroxy radicals, ethi emva koko iphendule ngepropylene ukuvelisa ipropylene oxide. I-catalyst idlala indima ebalulekileyo kule mpendulo, njengoko ithoba amandla okuvuselela afunekayo ukwenza i-peroxy radicals, ngaloo ndlela iphucula izinga lokuphendula.

Enye yezona zinto zisetyenziswa kakhulu ukwenza oku kusabela yi-silver oxide, elayishwa kwizinto ezixhasayo ezifana ne-alpha-alumina. Izinto ezixhasayo zibonelela ngomgangatho ophezulu we-catalyst, ukuqinisekisa uqhagamshelwano olufanelekileyo phakathi kwe-reactants kunye ne-catalyst. Ukusetyenziswa kwe-silver oxide catalysts kufunyenwe ukuba kubangele isivuno esiphezulu sepropylene oxide.

I-oxidation yepropylene usebenzisa inkqubo yeperoxide yenye indlela enokuthi isetyenziswe ukuveliswa kwepropylene oxide. Kule nkqubo, ipropylene iphendulwa nge-peroxide ye-organic phambi kwe-catalyst. Iperoxide idibana nepropylene yenze iradical free free radical, ethi yona ibole ivelise ipropylene oxide kunye notywala. Le ndlela inenzuzo yokubonelela ngokukhetha okuphezulu kwepropylene oxide xa kuthelekiswa nenkqubo ye-oxidation.

Ukhetho lweemeko zokusabela lukwabalulekile ekumiseleni isivuno kunye nokucoceka kwemveliso yepropylene oxide. Iqondo lobushushu, uxinzelelo, ixesha lokuhlala, kunye nomlinganiselo wemolekyuli yee-reactants zezinye zeeparamitha ezibalulekileyo ezifuna ukulungiswa. Kuye kwaphawulwa ukuba ukwandisa izinga lokushisa kunye nexesha lokuhlala ngokuqhelekileyo kubangela ukwanda kwemveliso yepropylene oxide. Nangona kunjalo, ukushisa okuphezulu kunokukhokelela ekubunjweni kweemveliso, ukunciphisa ukucoceka kwemveliso efunwayo. Ke ngoko, ulungelelwaniso phakathi kwezivuno eziphezulu kunye nokucoceka okuphezulu kufuneka kubethwe.

Ekugqibeleni, i-synthesis ye-propylene oxide esuka kwipropylene inokufezekiswa ngeendlela ezahlukeneyo, kubandakanywa i-oxidation kunye ne-molecular oxygen or peroxide process. Ukhetho lweemeko ze-catalyst kunye neemeko zokusabela zidlala indima ebalulekileyo ekumiseleni isivuno kunye nokusulungeka kwemveliso yokugqibela. Ukuqonda ngokucokisekileyo iindlela zokusabela ezibandakanyekayo kubalulekile ekuphuculeni inkqubo kunye nokufumana ipropylene oxide ephezulu.
