| abstract | PURPOSE: To readily obtain the above substance which is a raw material intermediate for medicines, engineering plastics, etc., without forming by-products by reacting a p-halogenated nitrobenzene as a starting raw material with sodium sulfide in water solvent containing a surfactant. n CONSTITUTION: A p-halogenated nitrobenzene (e.g. p-chloronitrobenzene or p-bromonitrobenzene) is used as a starting raw material and a surfactant is added into water solvent to disperse the raw material therein. Sodium sulfide is subsequently dropped (the sodium sulfide is preferably fed as an aqueous solution and the concentration thereof is 5-30wt.%, especially 15-25wt.% at 20-80°C temperature in dropping with holding time of 0.5-4hr after the dropping). Reductive reaction is then preferably carried out at 85-150°C in an inert gas atmosphere to afford the objective compound. n COPYRIGHT: (C)1990,JPO&Japio |
