Embodiment 1

[0029] A stable chlorite composition prepared from chlorite, guar gum or its derivatives, a buffer solution and an inorganic salt. According to the mass volume ratio, chlorite: guar gum or its derivatives: buffer solution: inorganic salt = 10g: 5g: 30mL: 100g. Wherein, the chlorite is sodium chlorite; the guar gum or its derivatives are non-ionic guar gum; the buffer solution is boric acid-sodium hydroxide buffer solution with pH=8; the inorganic salt is sodium chloride.

Embodiment 2

[0031] A stable chlorite composition prepared from chlorite, guar gum or its derivatives, a buffer solution and an inorganic salt. According to the mass volume ratio, chlorite: guar gum or its derivatives: buffer solution: inorganic salt=35g: 20g: 80mL: 150g. Wherein, the chlorite is potassium chlorite; the guar gum or its derivative is anionic guar gum; the buffer solution is a disodium hydrogen phosphate-potassium dihydrogen phosphate buffer solution with pH=12; the inorganic salt is magnesium chloride.

Abstract

The invention discloses a stable chlorite compound which is prepared from chlorite, guar gum or derivative thereof, a buffer liquid and an inorganic salt. The invention also discloses a preparation method of the stable chlorite compound. In the stable chlorite compound provided by the invention, the chlorite is dispersed and stabilized by the guar gum or derivative thereof, so that the chlorite can be stably stored for a long term under a solid gel state at room temperature. The stable chlorite compound can be conveniently transported and stored, and the safety in storage and transportation processes is promoted; the stable chlorite compound is prevented from explosion and combustion when the stable chlorite compound is mixed with organic matters, is abraded or is impacted; in a use process, when the stable chlorite compound is in contact with activating agents, such as acid, again, the two components can slowly react so as to generate chlorine dioxide; and an acceleration test at 54 DEG C proves that the chlorite content is still more than or equal to 70% after the chlorite solid component is stored for 85 hours at 54 DEG C.

Description

technical field [0001] The invention relates to a stable chlorite composition and a preparation method thereof, specifically belonging to the technical field of chemical industry. Background technique [0002] Chlorite, especially sodium chlorite, as an important industrial raw material, is often used in the fields of bleaching, decolorization and disinfection in papermaking and printing and dyeing industries. Chlorite is highly oxidizing and corrosive. During transportation and storage, it may occur naturally or explode when it collides with organic matter. At present, a large amount of industrial transportation needs to be transported in iron drums lined with plastic or formulated as a solution. But both forms of chlorite are still too dangerous for civilian use. [0003] As an important raw material of chlorine dioxide disinfectant, chlorite is used more and more in the civilian field. Chlorine dioxide preparations are often made in a binary form: one is a chlorite-con...
