| abstract | Alkali, or alkaline earth, metal, or ammonium monopersulphates are prepared by reacting the corresponding bisulphate and hydrogen peroxide at 50 DEG -110 DEG C. in the presence of an oxygen-containing inorganic acid in amount to provide 0,05-2 equivalents of hydrogen ion per kg. reaction mixture. The bisulphate may be produced in situ from sulphate and sulphuric acid, or by hydrolysis of pyrosulphate. Acids may be sulphuric, phosphoric, nitric, or perchloric acids. The hydrogen peroxide and bisulphate should be in molar ratio 1:1 to 5:1. The H2O2 should be at least 65% to ensure at least 1:1 ratio H2O2:H2O in the final reaction mixture, but the reaction may be effected under conditions to produce selective water removal. The monopersulphate may be isolated by neutralizing acid and selectively dissolving, or by selective crystallization. Stabilizers, e.g. dipicolinic acid, oxides of tin, or tetrasodium pyrophosphate, may be added to the mixture. Examples refer to the preparation of persulphates of sodium, potassium, ammonium calcium, and magnesium. |
