Abstract
The invention relates to a preparation method of a reactive chlorine dioxide solid preparation taking sodium chlorate as a raw material. The technical scheme of the invention comprises the following components: sodium chlorate, sodium bisulfate, sodium percarbonate, aluminum chloride and manganese sulfate. The mass ratio of each component is 3-5: 55-65: 1.5 to 2.5:0.05 to 0.1:0.05 to 0.1. The sodium percarbonate of the invention can be dissolved in acid solution to generate carbon dioxide, and can be used as protective gas of chlorine dioxide, so that the absorption of the chlorine dioxide is carried out stably; sodium percarbonate can be used as a disintegrating agent, and generated carbon dioxide gas can enable the solid preparation to be rapidly dissolved, so that the reaction rate is quickened. Aluminum ions and manganese ions formed by dissolving aluminum chloride and manganese sulfate in water can be used as catalysts, so that the time required by the reaction is reduced, and the synergistic effect is achieved; the chloride ion of aluminum chloride is used as an activator of the reaction, and can promote the speed of starting the reaction. The chlorine dioxide prepared by the reaction is high-purity gas, and the chlorine content is very small.
Description
Technical Field
The invention belongs to the field of disinfectant preparation. In particular to a preparation method of a reactive chlorine dioxide solid preparation taking sodium chlorate as a raw material.
Background
Chlorine dioxide has extremely strong oxidizing property, and researches show that the oxidizing capability is 2.7 times that of chlorine. Chlorine dioxide can react with many organic matters and inorganic matters rapidly, for example, harmful iron, manganese, nickel and other heavy metal ions can be converted into harmless states, phenols in sewage can be converted into chlorophenols by generating phenol free radicals to purify the sewage, and the chlorine dioxide can react with toxic naphthalene, aniline, formaldehyde and the like to be converted into harmless matters, and can kill bacteria, viruses, putrescence organisms and other internal enzymes through cell walls to further kill the bacteria, viruses, putrescence organisms and the like, thereby having a disinfection effect. The world health organization therefore authenticates chlorine dioxide as a class A1 disinfectant.
The chlorine dioxide has strong oxidizing property and the equal killing rate to various viruses can reach 100 percent. Chlorine dioxide and chlorine dioxide can maintain a constant sterilizing effect in a wider pH range, and the duration is long, so that the method is very suitable for household use.
Chlorine dioxide is active in nature and difficult to preserve, and is usually prepared into a stable solution or preserved in a solid preparation mode. For daily life, solid preparations which can be sterilized for a long time are obviously more convenient to use. Chlorine dioxide solid formulations are generally classified as adsorptive and reactive, and the reactive solid formulation material is typically sodium chlorate or sodium chlorite. Sodium chlorite is used as a reaction raw material in the market at present, but the price of sodium chlorite is more expensive than that of sodium chlorate, and the use cost is higher. In addition, sodium chlorite is difficult to preserve in a moist environment, which limits the environment in which such solid formulations can be used.
Disclosure of Invention
The invention aims to solve the problems of providing a preparation method of a novel chlorine dioxide solid preparation, which has low preparation cost and convenient raw material preservation, and the produced chlorine dioxide is high-purity gas.
The invention solves the problems by the following technical proposal:
a reactive chlorine dioxide solid preparation using sodium chlorate as raw material comprises sodium chlorate, sodium bisulfate, sodium percarbonate, aluminum chloride and manganese sulfate.
The mass ratio of the sodium chlorate to the sodium bisulfate to the sodium percarbonate to the aluminum chloride to the manganese sulfate is 3-5: 55-65: 1.5 to 2.5:0.05 to 0.1:0.05 to 0.1.
The mass ratio of the aluminum chloride to the manganese sulfate is preferably 1:2.
the preparation method of the reactive chlorine dioxide solid preparation taking sodium chlorate as a raw material comprises the following operation steps: mixing sodium chlorate, sodium bisulfate, sodium percarbonate, aluminum chloride and manganese sulfate according to the mass ratio to obtain a solid preparation, then adding water for dilution, and standing to release chlorine dioxide.
The raw materials are all powder after drying treatment.
The mass volume ratio of the solid preparation to water is 60-70 g: 400-600 mL, preferably 60-70 g:500mL.
The method of the invention has the following advantages:
the method for preparing chlorine dioxide by adopting sodium chlorate has the advantages of low cost, more stable property of sodium chlorate and easy preservation. Sodium percarbonate is used as a reducing agent, almost no byproducts are generated, the prepared chlorine dioxide is high-purity, and the sodium percarbonate is dissolved in sodium bisulfate solution to generate carbon dioxide as a shielding gas; the carbon dioxide generated by the sodium percarbonate has a disintegrating effect, can help the solid preparation to be dissolved rapidly, and reduces the waiting time of the reaction for generating the chlorine dioxide.
