실험 절차

126.5 g (1 mol) of benzyl chloride and 180 g (10 mol) of water were rapidly heated to reflux in a flask with baffles and propeller stirrer with vigorous stirring (250 rpm) under nitrogen. After 240 min reaction time, the mixture was rapidly cooled, the organic phase was separated off after addition of toluene, and analyzed by gas chromatography. It was found that 48 g of the benzyl chloride had been converted to give a yield of benzyl alcohol of 37 g and about 3.6 g dibenzyl ether, corresponding to a conversion of 38% and a yield of benzyl alcohol of 91%. The hydrochloric acid formed had a concentration of about 7.4%.
