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 zinc nitrite, nitrate Ph was adjusted to 3 by adding zinc powder, stirring for a few minutes to displace Cu2 +, Pb2 + plasma zinc nitrate effect, and then clarified After filtration the clear solution 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 a raw material of zinc nitrate solution, can save a step to remove impurities. Any chemical substance which has the danger of zinc nitrate having a corrosive and toxic decomposition stimulate zinc nitrate nitrogen oxide-containing gas at elevated temperature, if we breathe cause poisoning. The product also has an oxidizing, so we either in transport or operational use must be careful to avoid accidents. When we use plastic bags for packaging of zinc nitrate or two-story brown paper bag full open or in open drums; plastic bags or brown paper bags outside the ordinary wooden floor; threaded glass Lid pressure bottles, plastic bottles or metal (cans) outside the ordinary wooden box; threaded glass, plastic bottles or tinplate barrels (LP), full floor grille boxes, fibreboard or plywood box. In strict accordance with the "Dangerous Goods Code" in the dangerous goods were equipped fitted. Experimental zinc nitrate, zinc nitrate, three-level three-level chemical provided by Jinan Chemical Co., Ltd. Jinan three flat Chemical Co., Ltd. (www.sanpinghuagong.com) provide customers with "calcium nitrate, magnesium nitrate, zinc nitrate, magnesium sulfate, calcium sulfate, barium sulfate, ferrous sulfate, sulfur," and other services, the company has "Jinan three flat Chemical" and other brands. Focus on bio-fertilizer and other industries, have higher visibility in Jinan, Shandong. Welcomes inquiries, contact: Su Jingli.
