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 of melamine, 7.5 g of paraformaldehyde and 21.0 g of sodium dihydrogen phosphate dihydrate were charged into 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 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 present invention relates to the chemical industry, in particular to substances having antiseptic properties and to methods for obtaining such substances and their use. The substances according to the invention can be used as additives to filter materials or mixtures of filter materials, or as components of filter compounds for the disinfection and purification of liquids, preferably drinking water or gases. The anti-corrosion material of the present invention consists of a solid water-insoluble cross-linked polymer material containing chlorine atoms reversibly bonded to nitrogen atoms and represented by the general formula: M(F)1.0-5.5(Ph)0.6-1.0Cl-4.2 , wherein M is melamine, F-bridge and terminal group-formaldehyde derivatives, Ph-phosphorus with oxidation state of +5, Cl-chlorine atom connected to nitrogen atom, wherein the above-mentioned materials are obtained by combining phosphorus-containing ions with The melamine linking groups of the polymer chains are bonded to crosslink. The process of the present invention for obtaining anticorrosion material comprises chlorinating a solid water-insoluble cross-linked polymer material obtained by condensing melamine phosphate with paraformaldehyde in aqueous solution, wherein the above mentioned The polymeric material of ® is crosslinked by direct bonding of phosphorus-containing ions to the melamine linking groups of the polymer chains in the process for obtaining 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...
