Embodiment 1

[0029] Embodiment 1: each component and mass fraction proportioning: sodium chlorite (NaClO 2 ) 40, sulfamic acid (NH 2 SO 3 H)0, sodium bisulfate (NaHSO 4 ·H 2 O)20, magnesium sulfate (MgSO 4 ·7H 2 O) 2, sodium dichloroisocyanurate (C 3 o 3 N 3 Cl 2 Na) 22.

[0030] Inspection: draw 2ml of the solution with a pipette, and measure the percentage of chlorine dioxide to be 19.59% by the standard iodometric method.

[0031] The production process is the same as mentioned above.

Embodiment 2

[0032] Embodiment 2: each component and mass fraction proportioning: sodium chlorite (NaClO 2 ) 41, sulfamic acid (NH 2 SO 3 H)5, sodium bisulfate (NaHSO 4 ·H 2 O)30, magnesium sulfate (MgSO 4 ·7H 2 O) 0, sodium dichloroisocyanurate (C 3 o 3 N 3 Cl 2 Na) 18.

[0033] Inspection: draw 2ml of the solution with a pipette, and measure the percentage of chlorine dioxide to be 20.07% by standard iodometric method.

[0034] The production process is the same as mentioned above.

Embodiment 3

[0035] Embodiment 3: each component and mass fraction proportioning: sodium chlorite (NaClO 2 ) 42, sulfamic acid (NH 2 SO 3 H)8, sodium bisulfate (NaHSO 4 ·H 2 O)35, magnesium sulfate (MgSO 4 ·7H 2 O) 0, sodium dichloroisocyanurate (C 3 o 3 N 3 Cl 2 Na) 21.

[0036] Inspection: draw 2ml of the solution with a pipette, and measure the percentage of chlorine dioxide to be 20.60% by standard iodometric method.

[0037] The production process is the same as mentioned above.

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: [0001] The invention relates to the technical field of sterilizing and disinfecting agents, in particular to a chlorine dioxide solid preparation. Background technique: [0002] Chlorine dioxide (ClO 2 ) is listed as A1 grade bactericidal disinfectant by the World Health Organization (WHO) because of its high-efficiency, safety, and broad-spectrum bactericidal and disinfecting properties. It is widely used in various industries and has been generally recognized by people. [0003] In recent years, various types of chlorine dioxide solid preparations have been developed. The solid preparation of one-package uses a passivator to mix the generator (chlorite) and the solid activator together. When in use, a certain amount of solid preparation is dissolved in a certain amount of water, and a chemical reaction occurs to produce a clear yellow-green chlorine dioxide solution. According to the requirements of the object of use, dilute it into a chlorine dioxide s...
