\r\n\r\nAmmonium Sulphate (BOTEN)\r\n\r\nFaction and Use\r\n\r\nAn excellent fertilizer for general soil and crops, can make foliage vigorous growth,improve fruit quality and yield, enhance crop resistance to disasters can be used for basic fertilizer, top dressing fertilizer and seed. With salt metathesis reaction of manufacturing ammonium chloride, ammonium alum and aluminum sulfate is generated effects, together with boric acid and other manufacturing refractory materials. Plating solution can be added to increase the conductivity. The catalyst also food caramel, fresh yeast cultured yeasts produce nitrogen, acid dyes help agent, leather deliming agent. In addition, for beer brewing, chemical reagents and battery production. There is an important role in the exploitation of rare earth, ammonium sulfate as raw materials extraction, ion exchange in the form of the mineral soil in the rare earth exchanged out, and then collect leachate impurity removal, sedimentation, squeezing, burning Serve after rare earth ore, every exploration and production one ton of rare earth ore is about 12 tons of ammonium sulfate.\r\nUse biological lot, used for protein purification process, since ammonium sulfate are inert substance, the reaction hardly occurs with other biologically active substances that can maximize the protection of protein activity in the purification process, the addition of ammonium sulfate soluble polar Well, can form a high-salt environment, for protein precipitation and subsequent purification to prepare high salt. The solubility of ammonium sulfate at zero and room temperature of 25 degrees is quite different, the following is the molar concentration of ammonium sulfate at two different temperatures saturation.\r\n\r\nHanding Storage\r\n\r\nHandling Precautions: closed operation, local exhaust . The operator must go through specialized training , strict adherence to rules. Proposed operators wear self-absorption filter respirators , wearing chemical protective safety glasses, wear protective overalls on infiltration , wear rubber gloves . Avoid generating dust . Avoid contact with acids , alkalis . When moving to light light unloading , prevent damage to packaging and containers . Equipped with spill response equipment . Empty containers may be harmful residues .\r\nStorage: Store in a cool , ventilated warehouse. Away from fire, heat source. Should with acids, bases stored separately and avoid mixing reservoir. Storage areas should be equipped with suitable material spill .\r\n\r\nCaution\r\n\r\n( 1 ) can not be administered in combination with other alkaline fertilizer contact or mixed or alkaline substance , to prevent lower fertility.\r\n( 2 ) should not be on the same piece of arable land in the long-term application of ammonium sulfate , otherwise cause soil compaction become acid . When administered if it proves necessary , it may be appropriate with the application of lime or organic fertilizer. But we must be careful not to mix and lime applied to prevent decomposition of ammonium sulfate , resulting in nitrogen loss . Both complexes are generally administered to 3 to 5 days apart .\r\n( 3 ) suitable for application in acidic soils . Ammonium hydroxide , and sulfuric acid , the crystallization , centrifugation and drying derived.
