Benzhydrol → Butanoic acid, 3-oxo-, diphenylmethyl ester
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Benzhydrol | HCID 7037 | — |
| Reactant | Ethyl Acetoacetate | HCID 8868 | — |
| Solvent | Ethanol | HCID 702 | — |
| Product | Butanoic acid, 3-oxo-, diphenylmethyl ester | HCID 11149843 | 39.1% |
Reaction Steps
Benzhydrol (20 g, 0.1087 mole) and ethyl acetoacetate (13 g, 0.1 mole) were heated together to 170° and the ethanol so formed removed by distillation. Fractional distillation at 1.0 mm Hg yielded 10.5 g, 39% of benzhydryl acetoacetate as a colourless liquid which later solidified, melting point 44°-54°.
