AQUEOUS SOLUTION CONTAINING PERDICARBOXYLIC ACID

Japanese Patent JP3537540

B2

PURPOSE: To obtain an aqueous solution containing a perdicarboxylic acid, capable of efficiently forming a peracid by using a combined dicarboxylic acid and better in stability, performance or economical efficiency than those in the case of using a single carboxylic acid and useful for sterilizing, bleaching or cleaning.
CONSTITUTION: The aqueous solution containing a perdicarboxylic acid is obtained by reacting a combined dicarboxylic acid containing glutaric acid and succinic acid with hydrogen peroxide and contains (1) 0.05-1.0mol/kg solution (expressed in terms of monoperdicarboxylic acid) perdicarboxylic acid, (2) 0.2-2.2 mol/kg solution total dicarboxylic acids except the perdicarboxlic acid, (3) 1.0-12.0mol/kg solution hydrogen peroxide and (4) a stabilizer at 0.01-3.0wt.% concentration and the succinic acid (including persuccinic acid) at a concentration within the range of 0.1-0.7mol/kg solution succinic acid at 0.1-2.0 molar ratio of the succinic acid (including persuccinic acid) to 1mol glutaric acid (including perglutaric acid).
