METHOD OF PREPARING PHOSPHITE SOLUTION

摘要

FIELD: electrochemical techniques. SUBSTANCE: invention concerns preparing phosphorus compounds finding use as reducing agents. To this end, red phosphorus mixed with ethylenediamine aqueous solution is electrolyzed in diaphragmless electrolyzer at 70-95 C. EFFECT: increased yield of phosphites, reduced toxic hydrogen phosphide formation, and excluded formation of hypophosphites.
