9synthesis methods
-

Yield: 83.7%

Reaction Conditions:

Stage #1:perfluoropropanoyl fluoride with potassium fluoride at 20; for 24 h;Autoclave;
Stage #2:carbonic acid dimethyl ester with water at 20; for 36 h;Autoclave;

Steps:

3 Example 3
In a 1 L autoclave, add 200 ml of butyronitrile,0.5 mol of KF, 2 mol of pentafluoropropionyl fluoride,React at 20 degrees for 24 hours,Then, the remaining pentafluoropropionyl fluoride in the above reaction system is separated at -20 degrees.Then add 0.05 mol of water and 1 mol of dimethyl carbonate.After reacting at 20 degrees for 36 hours, after the reaction is over,Distillation to obtain heptafluoropropyl methyl ether (boiling point 6 ° C / 760 mmHg),The yield was 83.7% and the purity was 98.4%.
