I-Ethylene Glycol Ukukhiqizwa ngama-Intermediate Compounds
I-Hydrolysis ye-Ethylene Carbonate
Ukushiswa kwe-ethylene carbonate ukuze kukhiqizwe i-ethylene glycol kuhilela ukusabela kwe-carbon dioxide kanye ne-ethylene oxide ngaphansi kwe-catalyst ukuze kwakheke i-ethylene carbonate, bese kuba yi-hydrolyzed ibe yi-ethylene glycol. Uma kuqhathaniswa nokukhiqizwa kwe-ethylene glycol yendabuko, le ndlela inikeza izinzuzo eziningi:
Ukukhetha okuphezulu kwe-ethylene glycol, kufinyelela ku-99.3%–99.4%.
Izindleko zokukhiqiza eziphansi kakhulu zomkhiqizo ofanayo.
Izimo zokusabela ezithambile (izinga lokushisa eliphansi kanye nengcindezi), kunciphisa izidingo zamandla emishini kanye nokwehlisa izindleko zokutshalwa kwezimali cishe ngo-10%.
Izindleko zokusebenza zehle cishe ngo-5%, okwaholela ekusebenzeni kahle kwezomnotho, ukulondolozwa kwamandla, kanye nokuvikelwa kwemvelo.
