Abstract
The invention relates to the technical field of disinfectants, in particular to a solid preparation of chlorine dioxide. In recent years, various types of solid preparations of chlorine dioxide packed in single-ingredient are developed, but a common defect exists, namely the content of chlorine dioxide is low, no more than 8 percent in general, and the application range is limited. In the technical scheme of the invention, a mass part ratio of the components is as follows: 40 to 42 parts of sodium chlorite (NaClO2), 0 to 16 parts of sulfamic acid (NH2SO3H), 20 to 44 parts of sodium bisulphate (NaHSO4.H2O), 0 to 6 parts of magnesium sulfate (MgSO4.7H2O) and 18 to 22 parts of sodium dichloroisocyanurate (C3O3N3Cl2Na). In the solid preparation of chlorine dioxide of the invention, the content of chlorine dioxide can reach over 20 percent.
Description
Technical field:
The present invention relates to the disinfection sanitizer technical field, a kind of specifically solid preparation of chlorine dioxide.
Background technology:
Chlorine dioxide (ClO
2) because of it has efficiently, safety, broad-spectrum disinfecting performance are classified as A1 level disinfection sanitizer by The World Health Organization (WHO), use very extensively in all trades and professions, obtained people's generally approval.
In recent years, people develop various types of solid preparation of chlorine dioxide.The solid pharmaceutical preparation of monobasic packing utilizes a kind of passivator that propellant (chlorite) and solid activating agent are mixed together exactly.During use, a certain amount of solid pharmaceutical preparation is dissolved in a certain amount of water, chemical reaction takes place, promptly generate the yellow green ClO 2 solution of clarification.Requirement according to using object is diluted to certain density ClO 2 solution.
But, there is a common deficiency at present, be exactly that chlorine dioxide content is lower, generally be not more than 8%.Limited range of application equally.
Summary of the invention:
The purpose of this invention is to provide a kind of solid preparation of chlorine dioxide, chlorine dioxide content can reach more than 20%.
The each component of technical scheme of the present invention and mass fraction proportioning are as follows:
Sodium chlorite (NaClO
2) 40-42, sulfamic acid (NH
2SO
3H) 0-16, niter cake (NaHSO
4H
2O) 20-44, magnesium sulfate (MgSO
47H
2O) 0-6, sodium dichloro cyanurate (C
3O
3N
3Cl
2Na) 18-22.
Material content of the present invention is: sodium chlorite (NaClO
2) 82%, sulfamic acid (NH
2SO
3H) 99%, niter cake (NaHSO
4H
2O) 98%, magnesium sulfate (MgSO
47H
2O) 98%, sodium dichloro cyanurate (C
3O
3N
3Cl
2Na) available chlorine 61%.
In the above-mentioned prescription, sodium chlorite is the parent that produces chlorine dioxide, is the propellant of chlorine dioxide, and in theory, 1 gram content is the chlorine dioxide that 82% sodium chlorite should produce 0.489 gram, and promptly chlorine dioxide content is 48.9%;
Sulfamic acid promptly provides H+ for acidulant.Reaction equation:
5ClO
2 -+4H
+＝＝＝4ClO
2+2H
2O+Cl
Sulfamic acid is monobasic acid, that is: NH
2SO
3H==H
++ NH
2SO
3
How many sulfamic acids can calculate 1 gram sodium chlorite (82%) needs chlorine dioxide could be ejected.(chemical balance and reaction velocity problem are arranged) but in fact, the requirement of sulfamic acid exceeds more than three times than theoretical value.
Chemical reaction does not take place in passivator, only shields.Originally for the sake of security, the passivator consumption is more.
Because be the monobasic packing, total amount is fixed, i.e. the amount of the amount+passivator of the amount+sulfamic acid of total amount=sodium chlorite.Strengthen the amount of sulfamic acid and the amount of passivator, certainly will reduce the amount of sodium chlorite.The percentage composition of chlorine dioxide must reduce like this, originally is 3.5%, and prior art has reached 8% by experiment.
The sodium dichloro cyanurate that the present invention adopts both can play the passivation protection effect, can play activation again, as adjuvant.Because sodium dichloro cyanurate is water-soluble substances (especially in an acid medium), water-soluble back produces hypochlorous acid (HClO), produces chlorine dioxide with the sodium chlorite reaction:
3ClO
2 -+4HClO＝＝4ClO
2+3Cl
-+H
2O
Like this, reduced the consumption of passivator, increased the chlorine dioxide growing amount, so the content of chlorine dioxide has just improved.
Production technology of the present invention is as follows:
1, dry product of the present invention is responsive especially to water (vapour), and needed raw material is essential dry.Sulfuric acid oxygen sodium and magnesium sulfate need be at temperature drying and dehydrating below 70 ℃, the most handy anhydrides because of containing water of crystallization.Other raw materials can be dry about 100 ℃.Can not be higher than 50% air drying in humidity, atmosphere does not need protection.
2, pulverize with the abrasive method pulverizing, be crushed to and be not more than 0.175mm (80 order).If raw material is a powdery, can pulverize.
3, be blended in humidity and be not higher than in 50% the air, weighing is good in proportion with various raw materials, mixes to get final product in nonmetallic vessel.
4, the check product is uniform white multiphase solid powder.Water-soluble about 5min the yellow green clear solution, liquid level has chlorine dioxide to overflow.
Detection method: get 10g solid product of the present invention, be dissolved in the 1000ml volumetric flask.Treat to dissolve fully transparent after, with pipette, extract 2～5ml solution, with standard iodometric determination chlorine dioxide percentage composition.
5, packing plastic sack (PVC or PE) double casing.Every bag of net weight 100g or 500g.
The using method of product of the present invention:
With net weight is that the packing of product bag of 100g is opened, and slowly pours in the nonmetallic vessel that fills the peace and quiet water of 1000ml, and after the dissolving, the concentration of chlorine dioxide is 2% (20000ppm).Be diluted with water to corresponding concentration as required again.
Advantage of the present invention be actual use and transport in all very safe and convenient, reduced the consumption of passivator, increased the chlorine dioxide growing amount, chlorine dioxide content can reach more than 20%.
