• In order to prepare hydroxylamine from sodium nitrite, sodium bisulfite, and sulfur dioxide, liquid sulfur dioxide was used instead of gaseous one and the optimum condition for getting maximum yield was studied by rather quickly adding the dioxide. The best mole ratio of the material is as follows : NaNO_2 : NaHSO_3 : SO_2 = 1.0 : 1.0 : 0.95〜0.97. Even the excess of any component results less yield. The preparing time of sodium hydroxylamine disulfonate was reduced to 1/10〜1/20 by quickly adding liquid sulfur dioxide. But it was perceived that the yield was independent of the adding velocity of the sulfur dioxide. On the hydrolysis of the disulfonate in presence of sulfuric acid by direct heating, the hydrolyzing time was shortened. In total, the preparing time of hydroxylamine was shortened by about one tenth.
