| description | The invention discloses a method for continuously preparing perfluoropolyether by using a microchannel reactor. CF3CF2CF2O(CF2CF(CF3)O)CF(CF3)COOH used as a raw material reacts with F2 to obtain the corresponding perfluoropolyether. The method provided by the invention has the advantages of high conversion rate, short reaction time and safe and controllable reaction, and is suitable for industrialized amplification.
本发明公开了种利用微通道反应器进行全氟聚醚的连续制备的方法，以CFCFCFO(CFCF(CF)O)CF(CF)COOH为原料，与F反应得到相应的全氟聚醚。本发明提供的方法转化率高、反应时间短、反应安全可控和适合工业化放大。 |
