Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Ethyl 5-ethyl-2-methylfuran-3-carboxylate | HCID 12448862 | — |
| Solvent | Sodium Hydroxide | HCID 14798 | — |
| Product | 5-Ethyl-2-methylfuran-3-carboxylic acid | HCID 21433406 | — |
Reaction Steps
Saponification of 0.5 g of the ester was carried out by refluxing 4 hours in 10 ml of 25% aqueous sodium hydroxide. Acidification precipitated the crude acid, which was recrystallized from water to obtain 5-ethyl-2-methyl-3-furoic acid as white needles, mp 97°-99° C.
