Peroxymonosulfate compositions containing acylate oxidation promoters,and their use
Abstract
Abstract PARTICULATE COMPOSITIONS COMPRISING ADMIXTURES OF A WATER-SOLUBLE PEROXYMONOSULFATE AND A WATER-SOLUBLE SALT OF A 1 TO 4 CARBON SATURAED ALIPHATIC MONOCARBOXYLICACID AS AN OXIDATION PROMOTER; ALSO, AQUEOUS COMPOSITIONS WHICH ARE SOLUTONS OF SUCH A PEROXYMONOSULFATE HAVING A PH OF 5 TO 10 AND CONTAINING THE ACYLATE ANION OF SUCH AN ACID. SUCH SOLUTIONS ARE USEFUL FOR OXIDATIVE PURPOSES SUCH AS THE BLEACHING OF TEXTILES WHICH ARE AMENABLE TO BLEACHING WITH PEROXYMONOSULFATE, AND THE REMOVAL OF STAINS THEREFROM. THE PREFERRED PEROXYMONOSULFATE IS THE TRIPLE SALT OF POTASSIUM PEROXYMONOSULFATE OF THE FORMULA KHSO4.52SO4.2KHSO5. THE PRFERRED PROMOTERS ARE THE ALKALI METAL ACETATES, E.G., SODIUM ACETATE. THE PREFERRED PARTICULATE COMPOSITIONS ARE SUBSTANTIALLY ANHYDROUS ADMIXTURES OF THE ABOVE POTASSIUM PEROXYMONOSULFATE, SODIUM ACETATE, A BUFFERING AGENT SUCH AS TRISODIUM PHOSPHATE OR TETRASODIUM PYROPHOSPHATE, AND A SOLID DESICATING AGENT, PREFERABLY ANHYDROUS MAGNESIUM SULFATE.
