Abstract: An acid solution of hydroxylamine is prepared by adding a nitrite ester to an acid and reducing the ester with molecular H2 in the presence of a hydrogenation catalyst. The catalyst may contain a noble metal of Group VIII of the Periodic Table. The catalyst, e.g. Pt or Pd, may be supported on a carrier, e.g. C or Al2O3, and may be present as 100-3000 mg./l. of reactant liquor. Specified acids are H2SO4, H3PO4, NH4HSO4, and CH3COOH, and the temperature range may be 0-60 DEG C., maintained by a cooling jacket. The nitrite ester may be methyl, ethyl or butyl nitrite, which may be added at rate of 120-400 millimols/hr./l., with vigorous stirring. In the examples, the reaction mixture may also contain methyl, ethyl or butyl alcohols. The alcohol formed may be removed by distillation.
