    • Novel sulfonated phenyl esters of dicarboxylic acids are useful as diperoxyacid precursors in bleaching and laundering applications when combined with a source or peroxide. These diperoxyacid precursors can be produced by reacting a dicarboxylic acid, a phenol sulfonate, and a lower alkyl acid anhydride in an alkyl hydrocarbon solvent and removing a carboxylic acid by-product through distillation. The diperoxyacid precursors have the structure:
      wherein n is an integer from about 4 to about 18 and M is an alkali metal. an alkaline earth metal. or ammonium. The diperoxyacid precursors have a high perhydrolysis profile coupled with a relatively low-to-moderate hydrolysis profile.
    • 二羧酸的新颖的磺化苯基酯是如在漂白和洗涤应用diperoxyacid前体有用当与源或过氧化物组合。 这些diperoxyacid前体可通过在反应的二羧酸,苯酚磺酸酯,和低级烷基羧酸酐与烷基烃溶剂和副产物通过蒸馏除去羧酸来制备。 所述前体diperoxyacid具有以下结构: worin n是从约4至约18的整数,M是碱金属,碱土金属在,或铵。 所述前体diperoxyacid具有耦合具有相对低到中度水解轮廓的高的过水解轮廓。
