실험 절차

hydroxyadamantane were dissolved in 30 mls of HCOOH 98-100 %, and this solution was added dropwise, while stirring vigorously, to 1.5 1. of H2SO4 96% cooled to 5°C. Stirring was then continued at the same temperature for 90 minutes and the mixture was finally poured out on ice. NaOH was added to the mixture until it has a pH of approximately 1 and the formed precipitate was extracted with diethyl ether. The extract was dried over Na2SO4 and the solvent was then evaporated. The cruse 2-adamantyl carboxylic acid was thus obtained, which was purified by two crystallizations from 70% ethanol. The purified acid had a melting point of 142-144°C.
