I-Ethylene Glycol Direct Hydration ye-Ethylene Oxide.

I-Ethylene Glycol: Imizila Esekelwe Kuphethiloli kanye Namathemba Ayo
I-Ethylene glycol, eyaziwa nangokuthi i-glycol, iyinto ebalulekile eyisisekelo yezinto eziphilayo embonini yamakhemikhali kaphethiloli. Njengoba intengo kaphethiloli ishintshashintsha namuhla, ukuthola indlela engabizi yokukhiqizwa kwe-ethylene glycol sekuyindawo yokucwaninga. Leli phepha lihlaziya futhi liqhathanise imizila esekelwe kuphethiloli kanye nengeyona eyephethiloli yokukhiqizwa kwe-ethylene glycol, futhi libukeza izinzuzo kanye nokungalungi kwayo.

Lena yindlela yendabuko yokukhiqizwa kwe-ethylene glycol enkulu. Kule nqubo, i-ethylene oxide namanzi kuhlanganiswa ngesilinganiso se-molar esingu-1:20 kuya ku-1:22. I-ethylene oxide isabela ngokuphelele ukuze yakhe ingxube eluhlaza, eba ngaphansi kokuhwamuka okuningi ukuze iphelelwe amanzi emzimbeni kanye nokuhlukaniswa kwe-vacuum ukuze kutholakale i-ethylene glycol, kanye nemikhiqizo elandelanayo efana ne-diethylene glycol kanye ne-triethylene glycol. Isivuno sisonke singaba ngu-88%.

Ukwandisa inani lamanzi kunganciphisa ukwakheka kwemikhiqizo engaphansi futhi kuthuthukise izinga lokuguqulwa kwe-ethylene oxide. Kodwa-ke, ukungena kwamanzi amaningi kudala izinselele ezinkulu ekutholeni imikhiqizo ehlanzekile kakhulu. Ngaphezu kwalokho, imishini yokukhiqiza yale nqubo idinga ama-evaporator amaningi, futhi kusetshenziswa inani elikhulu lamandla ukuze kuhlukaniswe umkhiqizo, okuholela enkambisweni enokugeleza okude, ukutshalwa kwezimali kwemishini ephezulu, kanye nokusetshenziswa kwamandla aphezulu.
