Es ist bekannt, daß man aus der wäßrigen Lösung eingestellt. Man kühlt die Lösung auf 00C ab und läßt des N-Nitroso-N-cyclohexylhydroxylamin-Kaliumsal- eine Lösung aus 11,1 Teilen A12(SO4)3 · 18 H2O und zes durch doppelte Umsetzung mit Aluminiumsalzen 25 25 Teilen Wasser, die mit verdünnter Schwefelsäure von Mineralsäuren, beispielsweise Aluminiumchlorid (50%ig) auf einen pH-Wert von 1,5 bis 2 eingestellt oder Aluminiumsulfat, das N-Nitroso-N-cyclohexyl- wurde, rasch zulaufen. Die entstandene Fällung wird hydroxylamin-Aluminiumsalz erhält. nach einstündigem Nachrühren abfiltriert, mit WasserIt is known that one adjusts from the aqueous solution. The solution is cooled to 0 ° C. and the N-nitroso-N-cyclohexylhydroxylamine potassium salt is allowed to form a solution of 11.1 parts of A1 2 (SO 4 ) 3 · 18 H 2 O and zes by double reaction with aluminum salts 25 25 Parts of water which have been adjusted to a pH of 1.5 to 2 with dilute sulfuric acid of mineral acids, for example aluminum chloride (50%), or aluminum sulfate, which is N-nitroso-N-cyclohexyl, run in rapidly. The resulting precipitate is obtained as hydroxylamine aluminum salt. filtered off after stirring for one hour, with water
