Stage #2: Dimethyl etherwith water at 20; for 36 h;Autoclave;

Steps:

4 Example 4

In a 1 L autoclave, add 200 ml of valeronitrile,0.5 mol of AgF, 2 mol of heptafluoro-n-butyryl fluoride, reacted at 20 degrees for 24 hours,Then, the remaining heptafluoro-n-butyryl fluoride in the above reaction system is separated at 10 degrees.Then add 0.07 mol of water and 1 mol of dimethyl ether.React at 20 degrees for 36 hours,After the reaction is completed, distillation is carried out.Obtained nonafluorobutyl methyl ether (boiling point 61 ° C / 760 mmHg), the yield was 81.8%,The purity is 99.5%.
