Versuchsvorschrift

A 33.4 g (0.1 mole)-viscous liquid of 1,3-bis (4-nitrophenoxy)-2-propyl alcohol obtained in Example 6, 3 g of activated charcoal powder containing 5% Pd, and 250 ml of 1,4-dioxane were placed in a reaction vessel (hydrogenating apparatus). And the reaction mixtures were heated at 60° C. under a hydrogen atmosphere. In approximately 8 hours, 14.4 L of hydrogen was absorbed and the reaction was completed when the absorption of hydrogen stopped. Then the reacted solution was separated by filtration and the filtrate was concentrated for removing the catalyst. 27.4 g of 1,3-bis (4-aminophenoxy)-2-propyl alcohol was obtained.
