Chemical properties
Heated to 300 ¡æ under atmospheric pressure over the release of oxygen decompose in neutral or weak alkaline solution oxidation power is very low, but in acidic solution or induce oxidant and a catalyst (such as copper sulfate) is present, it is a strong oxidant with acids (eg sulfuric acid) effect the release of chlorine dioxide. have a strong oxidizing power with sulfur, phosphorus and organic mixture or by the impact, easy to cause a fire and explosion. deliquescent. acute oral LD50 1200mg/kg on the skin and mucous membranes local stimulation, preparation, 70% powder and 25% granules agents, toxic!
Printing and dyeing industry as a fabric dye Jing Yuan oxidant, but also for the mordant. Inorganic industry as oxidant, can also be used to make sodium chlorite, and perchlorate. Pharmaceutical industry for the manufacture of medicinal zinc oxide, sulfur sodium succinate. pigment used in the manufacture of zinc oxide and Westlands senior Agriculture used as herbicides. In addition, for paper making, tanning. Ore processing, and manufacture of bromine water to mention the printing ink, explosives, etc. [3]
