The raw material butanol, ethylene oxide and catalyst are sent to the reactor, and the reaction is carried out in the tubular microreactor. The reaction products are sent to the aging tank for distillation and separation. The unreacted butanol, monoethylene glycol butyl ether, diethylene glycol butyl ether, triethylene glycol butyl ether and polyethylene glycol butyl ether were separated by six columns.
