Zinc nitrate | Three flat Chemicals | zinc nitrate effect provided by the three-level Chemical Co., Ltd., Jinan. Road Zhiyuan, tempering forward. Jinan three flat Chemical Co., Ltd. (www.sanpinghuagong.com) strive to be and you win, symbiosis, strategic partners before the trip, the more determined to become the most influential bio-fertilizer business, and you leap together to success! Zinc oxide Synthesis of zinc nitrate in the reactor before adding a certain amount of water, nitric acid and stirring the ingredients by the ratio of zinc oxide to 1.6: 1 (according to the content of 100% basis) was added slowly to the Ph value of the reaction 3.5 to 4, and allowed to stand 24h, filtered, and the filtrate was diluted with water to 30 ~ 36 ° Bé, adjusted with nitric acid Ph 3 nitrous acid zinc, zinc powder is added and stirred for a few minutes to displace Cu2 +, Pb2 + plasma zinc nitrate reagent, and then clarify the experimental zinc nitrate , the supernatant obtained by filtration was acidified and concentrated by evaporation to 60 ~ 63 ° Bé, and then cooled with stirring to below 50 ℃, zinc nitrate was prepared products. Reaction equation is as follows: If more than 98% zinc oxide as raw material, can save a step to remove impurities. Zinc nitrate was dissolved was heated to 37 ℃ i.e. crystallization water. Lose all crystal water at 105 ~ 131 ℃. Irritating and toxic decomposition of nitrogen oxide gases at high temperatures, inhalation poisoning. The main purpose of zinc nitrate and bicycle parts for machine galvanized steel phosphating agent formulated, as a mordant, preservation agents and dyes synthetic materials like latex coagulation during dyeing.
