| In the recent past dentists were instrumental in the introduction of diethyl ether and nitrous oxide. |
| The animals were anesthetized with diethyl ether, and their abdomens were opened by a midline incision. |
| Percent fat was determined by lipid extraction with diethyl ether for 16 h in a Soxhlet apparatus. |
| The lipid was redissolved in diethyl ether that was then re-evaporated under nitrogen to complete dryness. |
| Thermolysis of such heterocyclic diethyl malonates results in the loss of one ester group by elimination of ethene and carbon dioxide. |
| Filtered cells were washed by centrifugation, twice with acetone and twice with diethyl ether. |
