Participants
| Role | Name | HCID | Charge |
|---|
| Reactant | Ethyl 4-oxocyclohexanecarboxylate | HCID 317638 | — |
| Solvent | Sulfuric Acid | HCID 1118 | — |
| Product | 4-Oxocyclohexanecarboxylic acid | HCID 192730 | 102% |
Reaction Steps
20 mmol (3.4 g) of 4-oxocyclohexanecarboxylic acid ethyl ester is suspended in 40 ml of 2% H2SO4 and stirred for 2 hours at 90° C. Then, it is extracted 4 times with ethyl acetate, dried with Na2SO4, and solvent is removed. Recrystallization is carried out from ether/hexane and yields 2.9 g of white solid 3.
