반응 단계
A solution of 1.80 g (0.014 mol) of 2-cyclopentenyl acetate in 3.80 g (0.12 mol) of methanol and 0.700 g of chlorobenzene (the internal standard for chromatographic analysis) was slowly passed through a jacketed column containing 20 ml of Dowex 1-X4 (an anion exchange resin of the quaternary ammonium type) in the hydroxide form in methanol. The column was maintained at 56° C by refluxing acetone in the jacket. The resin was then rinsed with methanol, and the combined effluent and rinsings were analyzed by gas chromatography using a 6ft. OV-17 column programmed from 80° to 220° C. The analysis showed that 2-cyclopentenol had beend formed in 96% yield and essentially 100% efficiency. No byproducts were observed.
