AI Technical Summary

Problems solved by technology

[0009] Its disadvantages are, inter alia, the high net costs and low ecological compatibility of its production method
Also, the method is very complex and has high power and energy consumption due to the use of expensive and toxic components, namely acetyl chloride and carbon disulphide, which pose a risk of explosion when their vapors come into contact with air
The use of this compound, which is dangerous to humans, can have adverse effects on the site where it is produced and the surrounding environment

Embodiment 1

[0026] 22.7 grams (g) of melamine phosphate, 7.5 g of paraformaldehyde and 4 g of NaOH were placed in a round bottom flask (200 ml) equipped with a mechanical stirrer, followed by 100 ml of water. The mixture was vigorously stirred (1200 rpm) at 90°C for 4 hours. The product obtained is in the form of porous particles with a size ranging from 0.3 to 2 mm. The mass of the obtained product was 29.8 g, and the molar ratio of melamine derivative / phosphorus / formaldehyde derivative was 110 / 92 / 2.47. The mole fraction of terminal methylol groups in the formaldehyde derivative is 0.013 (according to infrared spectroscopic data).

[0027] Particulate matter was flushed with a Buchner funnel.

[0028] The obtained polymer was chlorinated with 300 ml of a sodium hypochlorite solution having an active chlorine concentration of 52 g / l for 1 hour while stirring.

[0029] The chlorinated product was rinsed with water using a Buchner funnel until neutral, then dried at 50°C.

Embodiment 2

[0032] 12.6 g melamine, 7.5 g paraformaldehyde and 21.0 g sodium dihydrogen phosphate dihydrate were charged into a round bottom flask (200 ml) equipped with a mechanical stirrer, followed by 100 ml water. The mixture was vigorously stirred (1200 rpm) at 90°C for 4 hours. The product obtained is porous, in the form of granules with a size of 0.3-2 mm. The mass of product obtained was 29.2 g.

[0033] The molar ratios of the components are the same as in Example 1.

[0034] Particulate matter was washed with water using a Buchner funnel.

[0035] The obtained polymer was chlorinated with 300 ml of sodium hypochlorite solution having an active chlorine concentration of 52 g / L for 1 hour while being stirred.

[0036] The chlorinated product was rinsed with water using a Buchner funnel until neutral, then dried at 50°C.

[0037] The product contained 28% active chlorine (chlorine content estimated by iodometric titration).

Embodiment 3

[0039] The polymeric material was obtained by the method described in Example 1.

[0040] The product obtained was chlorinated while being mixed with an aqueous suspension of bleaching powder (80 g of CaCl(OCl)) and kept for 5 hours.

[0041] The chlorinated product was rinsed with acid (100 ml of a 10% solution) and water using a Buchner funnel and then dried at 50°C.

[0042] The product obtained contained 26% active chlorine.

Abstract

The invention relates to the chemical industry, in particular, to a substance which exhibits antiseptic properties and to a method for the production and use thereof. The inventive substance can be used as a filtering material or an additive for the mixture of filtering materials, or as a component of filtering composites used for disinfecting and cleaning liquids, mainly drinking water, or gases. The inventive antiseptic material consists of a solid non-water soluble cross-linked polymer material, which contains chlorine atoms reversibly bound with nitrogen atoms and is characterised by the following general formula: M(F)l.0-5.5(Ph)0,6-1.0Cl-4.2, where M - melamine, F - bridge and terminal groups-formaldehyde producers, Ph - phosphorus in oxidation state of +5, Cl - chlorine atoms bound with nitrogen atoms, wherein the above-mentioned material is cross-linked by binding phosphorus-containing ions with melamine links of polymer chains. The inventive antiseptic material producing method involves chlorinating the solid non-water soluble cross-linked polymer material which is produced by the condensation of melamine phosphate and paraform in an aqueous solution, wherein the above-mentioned material is cross-linked by binding the phosphorus-containing ions with the melamine links ofpolymer chains directly during the production process of said product.

Description

technical field [0001] The present invention relates to the chemical industry and in particular to substances having antiseptic properties, as well as to the production and use of such antiseptic substances. The invention can be used as an additive to filter materials or filter material mixtures or as a component of filter composites for the disinfection and purification of liquids, preferably drinking water or gases. Background technique [0002] According to U.S. Patent No. 4,594,392, there is known the existence of a stable composite form of halogenated and / or interhalogenated resins for water disinfection comprising copolymers of the form A / B-X, where X includes functional pyridyl C 5 h 5 Polyvinylpyridine of N, crosslinked with about 2% to 25% of divinylbenzene, where A / B is a combination of halogen and / or interhalogen, attached to the nitrogen atom of functional pyridyl X. The method for obtaining this material involves treatment with a solution of halides and / or met...
