ABSTRACT:
Aminonaphthalene derivatives are prepared by reacting the corresponding naphthol derivative with ammonia or amines in the presence of bisulfites. The reaction is carried out in a continuous procedure in reaction apparatus which consists wholly or partly of titanium or a titanium alloy, carbon largely excluded. Suitable alloys are titanium/palladium, titanium
ickel or titanium/molybdenum.
