Reaction Conditions:
with nitric acid at 85 - 90; for 10 h;
Steps:
1.S2; 2.S2; 3.S2; 4.S2; 5.S2
S2 Add 312g of purified perfluorohexylethanethiol and 780g of 30% nitric acid solution into a 5L glass reactor, the glass reactor is equipped with a heating device, a condenser, a magnetic stirrer and a thermometer. The stirring was started, and the temperature was slowly raised to 85 °C for 2 h, and then gradually raised to 90 °C to continue the reaction for 8 h. After the reaction was completed, 327 g of transparent paste-like liquid perfluorohexylethylsulfonic acid was obtained.
