Sodium Formate → Benzenamine, 3,3'-(1,3-phenylenebis(oxy))bis-

Participants

Reaction Steps

Into a glass vessel equipped with a thermometer, a reflux condenser and a stirrer were fed 1,3-bis(3-aminophenoxy)-5-chlorobenzene (8.2 g, 0.025 mol), 5% Pd-C (made by Japan Engelhardt Co.) (0.25 g), sodium formate (4.3 g, 0.063 mol) and 60% aqueous solution of isopropanol (50 ml), and reaction was carried out under reflux with stirring for 5 hours. After completion of the reaction, the catalyst was removed by filtering while hot, followed by cooling to deposit colorless, prismatic crystals, which were filtered and dried to obtain 1,3-bis(3-aminophenoxy)benzene (6.6 g, yield 90.3%). The purity according to high rate liquid chromatography was 99%. M.P.: 105°~107° C.
