Fast delivery CAS 111-46-6 Diethylene glycol

Production method :1. A diethylene glycol is a by-product of ethylene oxide in ethanol. Process: with a direct hydration method of ethylene oxide and water by 1: 8 mixed into the mixing reactor, at 150 ℃ MPa, the reaction 40-60min, the formation of dehydration tower further dehydration; bottom of the ethylene glycol mixture Into the ethylene glycol tower, the top of the tower can be more than 99.8% of ethylene glycol. The bottom of the column is fed to a retraction column and a diethylene glycol is obtained from the top of the column at a column temperature of 135-140 ° C and a pressure of 4.0 KPa. Continue to separate, available triethylene glycol, triethylene glycol. Refined method: contains impurities, water, ethylene glycol, triethylene glycol and so on. It can be refined by stepwise crystallization after distillation under reduced pressure. 1650 mL of diethylene glycol was fractionated by distillation under reduced pressure, and 480 mL of the initial fraction was discarded. 1000 mL of the middle distillate was collected for stepwise crystallization to obtain 700 mL of diethylene glycol.
2. with the role of acid anhydride ester, with alkyl sulfate or halogenated hydrocarbon role in ether.
3. Synthesis: from ethylene oxide and ethylene glycol produced by the role. Ethylene oxide is also a by-product of ethylene glycol.
