磷酸二氢铵与磷酸氢二铵有哪些地方不同?
来源:http://www.jnjrh.com 日期:2019-11-05 发布人:admin
  接下来,磷酸二氢铵——氨基磺酸厂家金日和化工将告诉你磷酸二氢铵和磷酸氢二铵的区别。具体内容如下:
  Next, ammonium dihydrogen phosphate - taurine manufacturer Jinri and chemical will tell you the difference between ammonium dihydrogen phosphate and ammonium dihydrogen phosphate. The details are as follows:
  1. 两者的不同用途:
  1. Different uses of the two:
  磷酸二氢铵:用作磷酸盐肥料、木材、纸张和织物的阻燃剂(如火柴棒和蜡烛芯),以及制药。也用作反刍动物的饲料添加剂。
  Ammonium dihydrogen phosphate: used as a flame retardant for phosphate fertilizer, wood, paper and fabric (such as matchsticks and candle wicks), as well as pharmaceuticals. It is also used as feed additive for ruminants.
  磷酸二铵:用于食品工业作发酵剂、面团调节剂、酵母饲料、发酵助剂等,主要用作高浓度氮磷复合肥,是一种肥料,广泛应用于蔬菜、水果、水稻、小麦等。
氨基磺酸
  Diammonium phosphate: it is used in food industry as starter, dough regulator, yeast feed, fermentation assistant, etc. it is mainly used as high concentration nitrogen and phosphorus compound fertilizer. It is a high-efficiency fertilizer, widely used in vegetables, fruits, rice, wheat, etc.
  2. 不同的生产方法
  2. Different production methods
  磷酸二氢铵:磷酸一氢铵复分解。磷酸与碳酸氢铵反应,再与氯化钾反应生成磷酸一氢钾的过程。
  Ammonium dihydrogen phosphate: double decomposition of ammonium monohydrogen phosphate. The process in which phosphoric acid reacts with ammonium bicarbonate and then with potassium chloride to form potassium monohydrogen phosphate.
  这是水、氯化钾、碳酸氢铵饲料的比例,然后加入指定数量的磷酸,充分搅拌,调节pH值,加热集中到110℃,冷却结晶后,离心分离,干燥产品KH2PO4,离心分离得到母亲溶液浓度是氮、磷、钾等多元素复合肥料。
  This is the proportion of water, potassium chloride, ammonium bicarbonate feed, then add the specified amount of phosphoric acid, stir it fully, adjust the pH value, heat it to 110 ℃, cool and crystallize it, centrifugate it, dry the product KH2PO4, centrifugally separate it to get the mother solution concentration of nitrogen, phosphorus, potassium and other multi-element compound fertilizer.
  磷酸氢二铵:将浓氨水缓慢加入磷酸氢二铵溶液中和至pH值为14,然后冷却、结晶、离心分离、干燥。
  Diammonium hydrogen phosphate: slowly add concentrated ammonia water into diammonium hydrogen phosphate solution and neutralize to pH value of 14, then cool, crystallize, centrifuge and dry.
  或以湿法磷酸为原料生产饲料用磷酸氢二铵,生产过程中需将磷酸三铵进行两步脱氟、三级氨化、裂解成饲料用磷酸氢二铵。生产成本低于黄磷。
  In the process of production, it is necessary to defluorinate triammonium phosphate in two steps, ammoniate it in three steps and split it into diammonium phosphate for feed. The production cost is lower than yellow phosphorus.
  3.不同的物理性质:
  3. Different physical properties:
  磷酸二氢铵:白色结晶粉末。稳定在空中。微溶于乙醇,不溶于丙酮。水溶液是酸性的。在室温(20℃)下,水的溶解度为37.4g。相对密度1.80。熔点是180℃。折光率1.525。
  Ammonium dihydrogen phosphate: white crystalline powder. Stay in the air. Slightly soluble in ethanol, insoluble in acetone. The aqueous solution is acidic. At room temperature (20 ℃), the solubility of water is 37.4g. The relative density is 1.80. The melting point is 180 ℃. The refractive index is 1.525.
  磷酸二铵:无色透明单斜晶或白色粉末。为了增加产品的耐储存性,在生产过程中有些产品加入了包装剂,使产品外观呈褐色。
  Diammonium phosphate: colorless transparent monoclinic crystal or white powder. In order to increase the storage resistance of products, some products are added with packaging agent in the production process, which makes the appearance of products brown.
