APPARATUS FOR PRODUCING HYDROXYLAMMONIUM SALT

摘要

The present invention is a production apparatus for producing a hydroxylammonium salt, whereby it becomes possible to prevent the corrosion of a reaction vessel in which a reduction reaction is to be carried out and therefore it becomes possible to produce a hydroxylammonium salt that does not undergo the deterioration in performance which is caused by the aforementioned corrosion. A production apparatus (100) according to the present invention is an apparatus for producing a hydroxylammonium salt by reducing nitrogen monoxide with hydrogen in an acidic medium in the presence of a catalyst. The production apparatus (100) is equipped with a reaction vessel (1), a first gas supply section (2), a second gas supply section (3) and a temperature control section (4). The reaction vessel (1) is so adapted as to store an acidic medium in which a catalyst is dispersed, and is also so adapted that a reduction reaction can be carried out therein. In the reaction vessel (1), at least a part which contacts with the acidic medium is formed from a two-phase stainless steel. The first gas supply section (2) can supply nitrogen monoxide to the reaction vessel (1), and the second gas supply section (3) can supply hydrogen to the reaction vessel (1). The temperature control section (4) can adjust the temperature in the reaction vessel (1) to a predetermined temperature.
