PROCEDURE

实验过程

34 g (0.19 mol) of trans-4-butylcyclohexylacetonitrile, 43 g (0.76 mol) of KOH, 34 cm3 of water and 190 cm3 of ethanol were refluxed on a hot water bath until formation of ammonia gas stopped. The ethanol in the reactant was removed, the residue was dissolved in 100 cm3 of water, it was poured into a beaker containing 100 cm3 of concentrated HCl and 100 g of ice, and the deposited crystals were filtered and washed in water. The crystals were recrystallized from a solvent mixture of methanol and water to obtain 37 g (0.19 mol) of trans-4-butylcyclohexylacetic acid.
