9synthesis methods
-

Yield: 92.8%

Reaction Conditions:

Stage #1:Carbonyl fluoride with cesium fluoride in acetonitrile at 20; for 24 h;Autoclave;
Stage #2:carbonic acid dimethyl ester with water at 20; for 24 h;Autoclave;

Steps:

1 Example 1
In a 1 L autoclave, add 200 ml of acetonitrile, 0.5 mol of CsF,2mol of carbonyl fluoride, reacted at 20 degrees for 24 hours,Then, the remaining carbonyl fluoride in the above reaction system is separated at -40 degrees.Then add 0.01 mol of water and 1 mol of dimethyl carbonate.After reacting at 20 degrees for 24 hours, after the reaction is over,Carry out distillation,Obtaining trifluoromethyl methyl ether (boiling point -25.2 ° C / 760 mmHg),The yield is 92.8%.The purity was 98.1%.
