氢氧化钾相对分子质量及用途解法那些事儿

发布来源:http://www.jinhao360.com    更新时间:2022-05-11 点击数:

氢氧化钾是一种常见的无机碱,常温下为白色粉末或片状固体。其性质与氢氧化钠相似。它具有强碱性和腐蚀性。那么氢氧化钾的相对分子量和用途是什么?
Potassium hydroxide is a common inorganic base, which is white powder or flake solid at room temperature. Its properties are similar to sodium hydroxide. It is highly alkaline and corrosive. So what is the relative molecular weight and use of potassium hydroxide?
钾的相对分子质量为39。相对分子质量是指化学式中各个原子的相对原子质量之和,用符号Mr表示,单位为1。对于聚合物来说,相对分子质量可以达到几万甚至几十万;相对分子质量最小的氧化物的化学式是H2O。相对分子质量在数值上等于摩尔质量,但单位不同。相对分子质量的单位是1,而摩尔质量的单位是g/mol。
The relative molecular weight of potassium is 39. Relative molecular mass refers to the sum of the relative atomic mass of each atom in the chemical formula, expressed by the symbol Mr, with the unit of 1. For polymers, the relative molecular weight can reach tens of thousands or even hundreds of thousands; The chemical formula of the oxide with the lowest relative molecular weight is H2O. The relative molecular mass is numerically equal to the molar mass, but in different units. The unit of relative molecular mass is 1, and the unit of molar mass is g / mol.
氢氧化钾仍被广泛使用,如无机工业用作生产高锰酸钾、亚硝酸钾、磷酸氢二钾等钾盐的原料。在日化工业中用作制造钾皂、洗洁精皂、洗发软皂、卸妆膏、冷霜、洗发水等的原料。医药工业用于制造黄体酮和黄体酮等原料。香草醛。
Potassium hydroxide is still widely used. For example, in inorganic industry, it is used as raw material for the production of potassium salts such as potassium permanganate, potassium nitrite and dipotassium hydrogen phosphate. In the daily chemical industry, it is used as raw materials for manufacturing potassium soap, detergent soap, shampoo, makeup remover, cold cream, shampoo, etc. The pharmaceutical industry is used to manufacture progesterone and progesterone and other raw materials. Vanillin.
染料工业用于制造三聚氰胺染料。电池工业用于制造碱性蓄电池。用作干燥剂、吸收剂,用于制造钾皂、草酸及各种钾盐,也用于电镀、雕刻、平版印刷等;主要用作生产钾盐的原料,如高锰酸钾、碳酸钾等。在电化学工业中,用于电镀、雕刻等。在纺织工业中,用于印染、漂白和丝光,广泛用作制造人造纤维和人造纤维的主要原料。聚酯纤维。
The dye industry is used to make melamine dyes. The battery industry is used to make alkaline batteries. It is used as desiccant and absorbent, in the manufacture of potassium soap, oxalic acid and various potassium salts, as well as electroplating, engraving, lithography, etc; It is mainly used as raw materials for the production of potassium salts, such as potassium permanganate, potassium carbonate, etc. In the electrochemical industry, it is used for electroplating, engraving, etc. In the textile industry, it is used for printing and dyeing, bleaching and mercerization. It is widely used as the main raw material for the manufacture of man-made fibers and man-made fibers. polyester.
汞电解液采用隔膜电解法制备。在电解室中,石墨(或金属)用作阳极,汞用作阴极。电解产生的氯气送入氯气干燥工序,产生的钾汞齐流入溶汞室。大部分未反应的氢氧化钾在淡盐水状态下处理,然后返回原料溶解过程。钾汞齐与水反应生成氢氧化钾和氢气。由于溶汞室的产品浓度为45%-50%,可作为液体产品使用,也可在碱性蒸煮锅中蒸煮浓缩成固体碱,或制成薄片产品。
Mercury electrolyte is prepared by diaphragm electrolysis. In the electrolytic chamber, graphite (or metal) is used as anode and mercury is used as cathode. The chlorine produced by electrolysis is sent to the chlorine drying process, and the generated potassium amalgam flows into the mercury dissolving chamber. Most of the unreacted potassium hydroxide is treated in light brine and then returned to the raw material dissolution process. Potassium amalgam reacts with water to produce potassium hydroxide and hydrogen. As the product concentration in the mercury dissolving chamber is 45% - 50%, it can be used as liquid products, or it can be steamed and concentrated into solid alkali in an alkaline cooking pot, or made into thin-film products.
氢氧化钾
将隔膜电解的原料氢氧化钾在溶盐槽中溶解成饱和溶液。加热至90℃时,分别加入碳酸钾、苛性钾、氯化钡,除去钙、镁、硫酸盐等杂质。将沉淀、除渣、盐酸中和、提纯后的含280-315g/L的溶液预热,电解得到氢氧化钾、氯气和氢气。隔膜法得到的产品浓度为10%-11%,需蒸发浓缩,冷却澄清,制成含45%-50%氢氧化钾的溶液;薄片作为薄片形式的氢氧化钾产物获得。
The raw material potassium hydroxide for diaphragm electrolysis is dissolved into a saturated solution in a salt dissolving tank. When heated to 90 ℃, add potassium carbonate, caustic potassium and barium chloride respectively to remove impurities such as calcium, magnesium and sulfate. Preheat the solution containing 280-315g / L after precipitation, slag removal, hydrochloric acid neutralization and purification, and electrolytic to obtain potassium hydroxide, chlorine and hydrogen. The product concentration obtained by diaphragm method is 10% - 11%, which needs to be evaporated, concentrated, cooled and clarified to make a solution containing 45% - 50% potassium hydroxide; The sheet is obtained as a potassium hydroxide product in the form of a sheet.
氢氧化钾的相对分子量及使用溶液为上述相关内容。如果您对本产品的使用有疑问,可以到www.jinhao360.com网站咨询我们。不要自己在家做实验,危险还是比较大的。
The relative molecular weight of potassium hydroxide and the solution used are related to the above contents. If you have any questions about the use of this product, you can go to www.jinhao360.com Com website. Don't do experiments at home by yourself. It's still dangerous.
