成分性质氨水又名氢氧化铵,是氨的水溶液,碱性,pH10左右,分子式为 NH_4OH,含氮12—16%。其制造原料是氮和氢,在500℃高温条件下,加入触媒剂,经高压合成氨(NH_3),将氨溶解在水里,即为农用氨水。氨水是我国小型氮肥厂主要产品之一,1979年氨水年产118.9万吨,占氮肥总产882.1万吨的13.3%。生产氨水比生产固体氮肥投资少,节约原料,因此施
Ingredients Ammonia, also known as ammonium hydroxide, is an aqueous solution of ammonia, alkaline, pH10 or so, the molecular formula NH_4OH, nitrogen 12-16%. The raw materials for its manufacture are nitrogen and hydrogen. Under the condition of high temperature of 500 DEG C, the catalyst is added and ammonia (NH_3) is synthesized by high pressure to dissolve the ammonia in the water, which is agricultural ammonia. Ammonia is one of the main products of China’s small-scale nitrogenous fertilizer plant. In 1979, the annual output of ammonia was 1.189 million tons, accounting for 13.3% of the total 8,821,000 tons of nitrogen fertilizer. Production of ammonia than the production of solid nitrogen fertilizer less investment, saving raw materials, so Shi
