Process for manufacturing highly concentrated hydroxylamine
An improved ion exchange process for manufacturing and concentrating hydroxylamine from an aqueous solution comprising hydroxylammonium ion and counter anions is disclosed. The process involves the use of an aqueous hydroxylamine wash step which assists in controlling the processing temperature and leads to a more concentrated, purified aqueous hydroxylamine solution.
