- Product Name:Methyl perfluoroisobutyl ether
- CAS Number:163702-08-7
- Molecular formula:C5H3F9O
- Molecular Weight:250.06
Yield:163702-08-7 83.2%
Reaction Conditions:
Stage #1: perfluoroisobutyryl fluoridewith silver fluoride at 20; for 24 h;Autoclave;
Stage #2: Dimethyl etherwith water at 20; for 48 h;Autoclave;
Steps:
5 Example 5
In a 1L autoclave,Add 200 ml of valeronitrile,0.5 mol of AgF,2 mol of heptafluoroisobutyryl fluoride, reacted at 20 degrees for 24 hours,Then, the remaining heptafluoroisobutyryl fluoride in the above reaction system is separated at 10 degrees.Then add 0.09 mol of water and 1 mol of dimethyl ether.After reacting at 20 degrees for 48 hours, after completion of the reaction, distillation was carried out to obtain nonafluoroisobutyl methyl ether (boiling point: 69-70 ° C / 760 mmHg), the yield was 83.2%, and the purity was 99.2%.
