PEROXOMONOCARBOXYLIC ACID AS WHITENER AND DISINFECTANT AGENT, AND A METHOD OF ITS PREPARING Russian patent published in 1994 - IPC

FIELD: chemical technology. SUBSTANCE: synthesis by a new method is carried out by electrolysis of alkaline metal hydrocarbonate, alkaline metal carbonate or ammonium carbonate aqueous solutions or their mixtures in anode space of diaphragm electrolyzer at anode current density 0,6-1,2 A/cm² or in the presence of alkaline metal or ammonium thiocyanate addition at current density 0,05-0,5 A/cm². Prepared acid shows good water-solubility, b. p. is 96-97 C, specific electric conductivity is 0.2946 Ohm/m, molar refraction is 12.734 x 12,734·10^-6 m³/mole. At storage concentrated solution of acid converters to the non-flowing gel. Acid is not toxic and can be used in foodstuffs for whitening and preservation of fruit juices against fermentation. EFFECT: synthesis of new acid with enhanced effectiveness. 3 cl, 4 tbl
