실험 절차
A solution containing 18 g of 4-ethylcinnamic acid dissolved in 50 mL of acetic acid was placed in a Parr Shaker bomb flask, 1.0 g of 5% palladium on carbon catalyst was added, and the flask was pressured to 50 psig (pounds per square inch gauge) (4460 kiloPascals) for 2 hours. The catalyst was then removed by filtration and the solution was concentrated by evaporation under reduced pressure. Water was added to the residue and the solid present was collected by filtration and dried under reduced pressure to obtain 3-(4-ethylphenyl)propanoic acid.
