氢氧化钾强碱性化工原料相关内容分享

发布来源:http://www.jinhao360.com    更新时间:2022-05-09 点击数:

  KOH又称苛性钾,一种强碱性化工原料。常用于制取碳酸钾、软肥皂、清洁剂和颜料等,在电镀、碱性电解质蓄电池等方面也有应用。下面来讲讲产品相关内容吧。
  KOH is also known as potash, a strong alkaline chemical raw material. It is often used to make potassium carbonate, soft soap, detergent and pigment, etc. It is also used in electroplating, alkaline electrolyte battery and so on. Let's talk about the product.
  固体氢氧化钾为白色正交结晶,易潮解并吸收二氧化碳。溶于水放出大量热,易溶于酒精和甘油。熔点℃。其化学性质类似氢氧化钠(烧碱),水溶液呈强碱性,能破坏细胞组织。
  Solid potassium hydroxide is a white orthogonal crystal that deliquesces easily and absorbs carbon dioxide. Soluble in water releases a lot of heat, soluble in alcohol and glycerin. Melting point ℃。 Its chemical properties are similar to sodium hydroxide (caustic soda), aqueous solution is strongly alkaline, can destroy cell tissue.
  有1、2、4分子水的水合物。固体氢氧化钾遇水或水蒸气产生热量,会使易燃物质达到燃烧温度,故应置于干燥场所贮存。接触氢氧化钾的防护措施同氢氧化钠。
  Hydrates with 1, 2, 4 molecules of water. When solid potassium hydroxide encounters water or steam, it will generate heat and make flammable substances reach combustion temperature. Therefore, it should be stored in a dry place. Protective measures for contact with potassium hydroxide are the same as sodium hydroxide.
  氢氧化钾可从电解高纯度的氯化钾水溶液制得。所用的电解槽形式以及生产过程类似氢氧化钠。使用隔膜电解槽时,所得的电解液含有10%~15%(质量)的氢氧化钾和约10%(质量)的氯化钾。
  Potassium hydroxide can be prepared by electrolysis of a highly purified aqueous solution of potassium chloride. The electrolytic cell used and its production process are similar to sodium hydroxide. When a diaphragm cell is used, the resulting electrolyte contains 10% ~ 15% (mass) potassium hydroxide and approximately 10% (mass) potassium chloride.
  经蒸发、浓缩、冷却,大部分的氯化钾结晶析出,分离后得到含氢氧化钾45%~50%的产品(含氯化钾%)。
  After evaporation, concentration and cooling, most of the potassium chloride crystallizes out, and after separation, the product containing 45% ~ 50% potassium hydroxide (containing % potassium chloride) is obtained.
  采用水银电解法可以制得高纯度的氢氧化钾,但应控制氯化钾水溶液中重金属杂质的含量在以下,以免氯气中含氢过高。采用离子膜电解法须使用专用的离子交换膜。
  High purity potassium hydroxide can be prepared by mercury electrolysis, but the content of heavy metal impurities in potassium chloride aqueous solution should be controlled below, so as not to contain too much hydrogen in chlorine gas. Ionic membrane electrolysis requires the use of a special ion exchange membrane.
  氢氧化钾比氢氧化钠难于脱水。工业固体氢氧化钾的纯度为88%~92%,固体有块状和片状两种。液体氢氧化钾有45%和50%两种浓度规格。
  Potassium hydroxide is more difficult to dehydrate than sodium hydroxide. The purity of industrial solid potassium hydroxide is 88% ~ 92%, and there are two kinds of solid: block and flake. Liquid potassium hydroxide is available in 45% and 50% concentration specifications.
