<p>The invention relates to chemistry, in particular to the production of disinfectants which are based on polyalkylene guanidines and polyoxialkylene guanidines and can be used as environmentally safe and efficient disinfectants for medicine, veterinary, water treatment for water purification and for various sectors of national economy where the use of biocidal (antiseptic) agents is required. In order to increase antiseptic properties of an end product, the inventive method for producing an disinfectant by means of polycondensation of guanidine salts with amines in equimolar ratio by heating, purifying from impurities of unreacted substances when necessary, drying and cooling a product. The purification is carried out after the polycondensation. Melt is cooled by division thereof into discrete drops inside airflow, said drops being afterwards granulated. The obtained product is non-toxic and of high performance.</p> |
