Synthesis of zinc nitrate, zinc oxide 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, standing 24h, filtered, and the filtrate was diluted with water to 30 ~ 36 ° Bé, adjusted with nitric acid Ph 3 experimental zinc nitrate, zinc powder is added and stirred for a few minutes to displace Cu2 +, Pb2 +, plasma, and then clarify zinc nitrate, pumping The resulting supernatant was filtered through acidification, and concentrated by evaporation to 60 ~ 63 ° Bé, and then cooled with stirring to below 50 ℃ zinc nitrite, 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, zinc oxide and nitric acid is a certain ratio of zinc nitrate to react industrial, zinc dust is added to the replacement of the other metal ions, and then by filtration, the filtrate was acidified with concentrated by evaporation, cooled to obtain a zinc nitrate product. Bicycle parts for machines and galvanized steel phosphating agent formulation, when used as a mordant dyeing, preservation agents and synthetic latex coagulating agent dye items.
