| description | The invention relates to applied electrochemistry and can be used for technical areas in which disinfecting agents are used for disinfecting and sterilising different objects in the industry and public health. The disinfecting agents are embodied in the form of oxidant aqueous chlorine-containing solutions whose pH is equal to 7.5, total salt content ranges from 0.2 to 2.0 g/l and oxidant content ranges from 80 to 1000 mg/l. The inventive method for producing said agents consists in treating an initial aqueous alkali metal chloride solution in the anode chamber of a diaphragm electrochemical reactor, in introducing a corrosion inhibitor embodied in the form of a low-molecular mono- or a diatomic alcohol or the mixture thereof, wherein a corrosion inhibitor is introducible into the oxidant solution in the quantity of equal to or less than 10 % by volume after the treatment in said anode chamber or prior to the use. The quantity of the introducible ethanol is determined by formula Cal= (18.4x CNaCl)x Cox, wherein Cal is the ethanol concentration, in mmol/l, CNaCl is the concentration of initial sodium chloride solution, in g/l, Cox is the oxidant concentration, in mmol/l. Methods for producing the oxidant aqueous solutions and the inventive disinfecting agent are also disclosed.
L'invention appartient au domaine de l'électrochimie appliquée et peut s'utiliser dans les domaines techniques où l'on emploie des produits désinfectants utilisés pour la désinfection et la stérilisation de différents objets, en industrie comme en médecine. Selon l'invention, on introduit en tant qu'inhibiteur de corrosion dans des produits désinfectants, qui se présentent comme des solutions aqueuses chlorées d'oxydants avec un pH 6,5 - 7,5, avec une teneur globale en sel de 0,2 - 2,0 g/l et une teneur en oxydants de 80 à 1000 mg/l (et dont le procédé de fabrication comprend le traitement d'une solution aqueuse initiale d'un chlorure de métal alcalin dans une chambre anodique d'un réacteur électrochimique à diaphragme), un alcool à faible poids moléculaire à un ou deux atomes ou un mélange de ces alcools, l'inhibiteur de corrosion étant introduit dans la solution d'oxydants dans des quantités allant jusqu'à 10 % en volume après le traitement dans une chambre d'anode, ou avant l'utilisation. La quantité d'éthanol introduite est déterminé selon la formule Cal=(18,4 x CNaCl)x Cox, dans laquelle Cal est la concentration d'éthanol, m mol/l CNaCl est la concentration de chlorure de sodium |
