Abstract

PURPOSE: To facilitate separation of the title sulfonic acid and to enable the acid to be produced in a high yield by reacting NH2OH or its mineral acid salt with fuming sulfuric acid in the presence of a sulfate selected from ammonium sulate, sodium sulfate and gypsum.
CONSTITUTION: NH2OH or its mineral acid salt such as sulfate is reacted with a slightly excess amt. of 10W60% fuming sulfuric acid in the presence of a sulfate such as ammonium sulfate in an amt. of 0.1W1.5 parts by wt. to 1 part of NH2OH. The reaction is carried out at 20W100°C under ordinary press. for 1W5 hr. After the reaction the reaction mixt. is cooled for about 30 min W 2 hr to well crystallize hydroxylamine-O-sulfonic acid, which is then separated. The reaction mixt. may be mixed with an acetic acid ester to further enhance the purity of the sulfonic acid. By this method the sulfonic acid is obtd. as a mixt. of the acid and the used sulfuric acid, they, however, are separated by suitable operation such as extraction to give a pure product.
