Nitroso-b-naphthol has been made by the action of hydroxylamine
hydrochloride on b-naphtho-quinone-chlorimide;[1] by the action
of sulfuric acid upon a solution of potassium or sodium nitrite
and the sodium salt of b-naphthol;[2] by the action of sodium nitrite
upon an alcoholic solution of zinc chloride and b-naphthol;[3]
by the action of sodium nitrite upon b-naphthol suspended in zinc
sulfate solution;[4] by the action of nitrous acid on b-dinaphthol
methane;[5] and by the action of nitrosyl sulfate upon the sodium
