| description | The utility model belongs to the field of fluorine-containing fine chemical engineering, and particularly relates to a device for preparing perfluoromethoxy methyl vinyl ether. The device comprises a reaction kettle, the top of the reaction kettle is connected with a reflux condenser, an inner cavity of the reaction kettle is provided with an ultrasonic stirrer and a gas inlet pipe, and a gas outlet of the gas inlet pipe is connected with a gas distributor for uniformly distributing fluorine gas. According to the device for preparing the perfluoromethoxy methyl vinyl ether, gas and liquid phases in the reactor are uniformly mixed through the cavitation effect of the ultrasonic stirrer to achieve the heat and mass transfer effect, the reaction yield is high, the device can stably run for a long time at the ultralow temperature of-120 DEG C due to the fact that a movable sealing piece is not involved, and in the reaction process, the reaction time is greatly shortened.
