PROCESS FOR PROCESSING ETHYLENE OXIDE STREAMS CONTAINING NOXOR ORGANIC NITROGEN COMPOUNDS

摘要

Crude aqueous alkylene oxide streams are converted to the corresponding a lkylene glycol. The crude alkylene oxide stream contains NOx or organic nitr ogen compounds. The hydrolysis reaction is conducted in the presence of wate r-soluble reducing agents, of which an alkali metal bisulfite is a preferred type.
