いる。The basic chemical reaction of stable chlorine dioxide active gas is an oxidation reaction, not chlorination as seen in other chlorine-based substances. This active gas does not easily react with aliphatic amines, polysaccharides, and saturated fatty acids such as maleic acid and fumaric acid. This means that it does not react with natural sugars, does not damage cellulose, and therefore does not damage fruits and vegetables.

り分解し、二酸化塩素ガスを発生する。Therefore, solid chlorite is stable, and in particular, alkali metal salts such as sodium chlorite and potassium chlorite, and alkaline earth metal salts such as calcium chlorite have a decomposition temperature of 180~180℃. Since the temperature is 200°C, chlorine dioxide gas is not generated under normal conditions, but chlorinated cyanuric acid consisting of trichloroisocyanuric acid, sodium dichloroisocyanurate, potassium dichloroisocyanurate, and mixtures thereof can be used as a reactant. When used, it decomposes and generates chlorine dioxide gas.

とができる。The above reactant is hydrolyzed by moisture in the air to liberate hypochlorous acid. Chlorine dioxide gas is generated by the reaction between this liberated hypochlorous acid and chlorites. Furthermore, the rate of generation of chlorine dioxide gas can be controlled by changing the weight ratio and pH of each of these components.
特に重要なのはｐＨであり、これが８前後になるよう調
節しておくと、ガス発生速度が抑制されるので、６ケ月
以上の長期にわたって二酸化塩素ガスを発生させること
かできる。Particularly important is the pH, and by adjusting the pH to around 8, the rate of gas generation is suppressed, so chlorine dioxide gas can be generated over a long period of six months or more.
