為大家介紹氫氧化鉀的合成原理有哪些?

發布來源:http://chungcumysontower.com    更新時間:2021-06-24 點擊數:

氫氧化鉀白色粉末或片狀固體,具強堿性及腐蝕性,易吸收空氣中水分而潮解,吸收二氧化碳而成碳酸鉀。用作干燥劑、吸收劑,用于制草酸及鉀鹽,還用于電鍍、雕刻、石印術。那氫氧化鉀的合成原理是什么樣呢?今天就讓我們氫氧化鉀廠家為大家介紹氫氧化鉀的合成原理有哪些?

Potassium hydroxide white powder or flake solid, with strong alkaline and corrosive, easy to absorb moisture in the air and deliquescence, absorption of carbon dioxide and potassium carbonate. It is used as desiccant, absorbent, oxalic acid and potassium salt, electroplating, carving and lithography. What is the synthesis principle of potassium hydroxide? Today, let's introduce the synthesis principle of potassium hydroxide?
一、水銀電解法電解液的配制同隔膜電解法。電解室中以石墨(或金屬)作陽極,水銀作陰極,電解產生的氯氣送氯氣干燥工序,生成的鉀汞齊流入解汞室。大部分未反應的氫氧化鉀以淡鹽水狀態經處理后,返回原料溶解工序。鉀汞齊與清水反應生成氫氧化鉀和氫氣。因解汞室出來的氫氧化鉀濃度為45%至50%,可作為液體氫氧化鉀產品,也可再經熬堿鍋蒸濃成固堿或制成片狀氫氧化鉀產品。
氫氧化鉀
1、 The preparation of electrolyte for mercury electrolysis is the same as that for diaphragm electrolysis. In the electrolysis chamber, graphite (or metal) is used as anode and mercury as cathode. The chlorine generated by electrolysis is sent to the chlorine drying process, and the potassium amalgam generated flows into the mercury dissolving chamber. Most of the unreacted potassium hydroxide is treated in the state of dilute brine and then returned to the raw material dissolution process. Potassium amalgam reacts with water to produce potassium hydroxide and hydrogen. Because the concentration of potassium hydroxide from the mercury dissolving chamber is 45% to 50%, it can be used as liquid potassium hydroxide product, or evaporated to form solid alkali or flake potassium hydroxide product.
二、隔膜電解法原料氫氧化鉀在化鹽槽溶化成飽和溶液,加熱至90℃時分別加入碳酸鉀、苛性鉀、氯化鋇除去鈣、鎂和硫酸根等雜質,經沉降除渣、鹽酸中和、精制的含氫氧化鉀280至315g/L的氫氧化鉀溶液經預熱到70至75℃后進行電解,得氫氧化鉀、氯氣和氫氣。隔膜法所得氫氧化鉀濃度為10%至11%,需通過蒸發濃縮和冷卻澄清,制得含45%至50%氫氧化鉀溶液;也可繼續在熬堿鍋中濃縮,經脫色,制得固體氫氧化鉀,或經制片成片狀氫氧化鉀產品。
2、 Potassium hydroxide, the raw material of diaphragm electrolysis, is dissolved into saturated solution in the salt bath. When heated to 90 ℃, potassium carbonate, caustic potassium and barium chloride are added to remove impurities such as calcium, magnesium and sulfate. After sedimentation and slag removal, hydrochloric acid neutralization and refining, the 280-315g / L potassium hydroxide solution containing potassium hydroxide is preheated to 70-75 ℃ for electrolysis to obtain potassium hydroxide, chlorine and hydrogen. The concentration of potassium hydroxide obtained by diaphragm method is 10% to 11%, and the solution containing 45% to 50% potassium hydroxide is prepared by evaporation concentration and cooling clarification; It can also continue to concentrate in the alkali boiling pot and decolorize to produce solid potassium hydroxide or flake potassium hydroxide products.
另外工業上制取氫氧化鉀是電解氫氧化鉀的水溶液。因為氫氧化鉀比氫氧化鈉難脫水,市售品的純度一般只能達到85%至86%。如需提純可按照提純氫氧化鈉的相同的方法進行提純。以上就是我們氫氧化鉀廠家為大家介紹氫氧化鉀的合成原理,更多的知識歡迎關注我們的網站。
In addition, the industrial preparation of potassium hydroxide is the aqueous solution of electrolytic potassium hydroxide. Because potassium hydroxide is more difficult to dehydrate than sodium hydroxide, the purity of commercial products can only reach 85% to 86%. If purification is needed, the same method can be used to purify sodium hydroxide. The above is our potassium hydroxide manufacturers to introduce the synthesis principle of potassium hydroxide, more knowledge welcome to pay attention to our website.
