Embodiment 1
[0062] 1) With 30ml isopropanol as solvent, 0.3mol 1H,1H-perfluorohexylamine and 0.33mol 1-bromopentane were reacted under reflux for 24 hours at 85°C. After the reaction was completed, the volatile components were distilled off under reduced pressure. Then use 400ml of ethyl acetate and acetone mixed solution (volume ratio 1:10) to recrystallize once to obtain 0.23mol of product I-1.
[0063] 2) Mix 0.22 mol of the product of the above step 1) with 0.1 mol of 1-chloroethyl chloroformate, use 30 ml of isopropanol as a solvent, and reflux at 85° C. for 40 hours. After the reaction, the volatile components are removed by distillation under reduced pressure. Wash once with 100ml of petroleum ether and 50ml of diethyl ether, and recrystallize once with a mixed solution of 400ml of ethyl acetate and acetone (volume ratio 1:6) to obtain 0.08mol of product II-1.
[0064] 3) In the presence of 0.154 mol of sodium hydroxide, mix 0.07 mol of the above-mentioned product II-1 with 0.154 m...
Embodiment 2
[0068] 1) With 30ml of isopropanol as solvent, 0.3mol 1H,1H-perfluorooctylamine and 0.33mol 1-bromodecane were reacted under reflux for 24 hours at 85°C. After the reaction was completed, the volatile components were distilled off under reduced pressure. Then use 400ml of ethyl acetate and acetone mixed solution (1:10 by volume) to recrystallize once to obtain 0.24mol of product I-2.
[0069] 2) Mix 0.22 mol of the product of the above step 1) with 0.1 mol of 1-chloroethyl chloroformate, use 30 ml of isopropanol as a solvent, and reflux at 85° C. for 40 hours. After the reaction, the volatile components are removed by distillation under reduced pressure. Wash with 100ml of petroleum ether and 50ml of diethyl ether for 3 times, and recrystallize once with a mixed solution of 400ml of ethyl acetate and acetone (volume ratio 1:6) to obtain 0.09mol of product II-2.
[0070] 3) In the presence of 0.154 mol of sodium hydroxide, mix 0.07 mol of the above product II-2 with 0.154 mol o...
Embodiment 3
[0074] 1) With 30ml isopropanol as solvent, react 0.3mol 1H, 1H-heptadecafluorononylamine and 0.33mol 1-bromopentadecane under reflux for 24 hours at 85°C, and distill under reduced pressure to remove the volatile components, and then recrystallized once with a mixed solution of 400ml ethyl acetate and acetone (volume ratio: 1:10) to obtain 0.23mol of product I-3.
[0075] 2) Mix 0.22 mol of the product of the above step 1) with 0.1 mol of 1-chloroethyl chloroformate, use 30 ml of isopropanol as a solvent, and reflux at 85°C for 40 hours. 100ml of petroleum ether and 50ml of diethyl ether were washed once respectively, and then recrystallized once with a mixed solution of 400ml ethyl acetate and acetone (volume ratio 1:6) to obtain 0.07mol of product II-3.
[0076] 3) In the presence of 0.154 mol of sodium hydroxide, mix 0.07 mol of the above-mentioned product II-3 with 0.154 mol of 2-chloroethanol, use 30 ml of acetonitrile as solvent, react at 85°C for 60 h, and distill unde...
