Aqueous hydroxylamine solution |
| abstract |
An aqueous hydroxylamine solution containing hydroxylamine in an amount of 30 wt. % or more, which contains iron in an amount of not more than 10 ppb, metal components other than iron in an amount of not more than 5 ppb for each metal component and trans-1,2-diaminocyclohexane-N,N,N′,N′-tetraacetic acid in an amount of 0.0005 to 0.5 wt. % is obtained by distillation of a concentrated aqueous crude hydroxylamine solution using a specifically surface treated distilling apparatus. |
