反応手順
A mixture of 69 g (1.0 mol) of sodium nitrite, 53 g (0.5 mol) of sodium carbonate, 5 g (0.01 mol) of hexadecyltributyl-phosphonium bromide, 220 ml of water and 78.5 g (0.5 mol) of 4-chloro-nitrobenzene is heated to 140° C. for 7 hours. After cooling, the solid product is filtered off and washed, first with a little dilute hydrochloric acid and then with a little alcohol. After drying, 61 g (91.5% of theory) of 4,4'-dinitrodiphenyl ether (melting point: 139°-140° C.) are obtained.
