PREPARATION OF MONOALKYLENE GLYCOLS IN TWO STAGES |
摘要 |
PREPARATION OF MONOALKYLENE GLYCOLS IN TWO STAGES High selectivity to monoalkylene glycol is obtained by contacting in an associated moiety-forming zone alkylene oxide and a selectivity enhancing, dissociatable metalate anion under conditions sufficient to associate at least a portion of the alkylene oxide with metalate anion, and then contacting the associated moiety with water in a glycol-forming zone to form alkylene glycol. The alkylene glycol can be separated from metalate anion. Desirably, the metalate anion can be recycled to the associated moiety-forming zone. |
