반응 단계
Into a 1 L beaker were weighed 222 g (1.0 mol) of 4-(benzyloxymethyl)-2,2-dimethyl-1,3-dioxolane prepared in 1-2, 250 ml of ethanol, and 400 ml of distilled water, and the whole was adjusted to pH 2 with phosphoric acid. With introducing nitrogen thereinto, the solution was heated to 70° C. After 1.5 hours of the reaction, the solution was adjusted to pH 7.0 with sodium hydroxide. The resulting salt was subjected to adsorption treatment with an adsorbent “KYOWAAD 1000” (manufactured by Kyowa Hakko Kogyo Co., Ltd.) and then subjected to solvent removal to obtain 3-benzyloxy-1,2-propanediol.
