萬博官方manbext網頁版|萬博manbext手機|萬博manbetx官網乙醇溶液主要用途有哪些?

萬博官方manbext網頁版|萬博manbext手機|萬博manbetx官網化學式:KOH,能溶于水和乙醇,在溶解時會發出大量的熱量,具有強堿性和腐蝕性,當其暴露在空氣中時極易吸收空氣中的水分而發生潮解,或吸收空氣中的二氧化碳生成碳酸鉀。

Potassium hydroxide chemical formula: Koh, soluble in water and ethanol, when dissolved, it will emit a lot of heat, with strong alkaline and corrosive, when it is exposed to the air, it is very easy to absorb water in the air and deliquescence, or absorb carbon dioxide in the air to generate potassium carbonate.
萬博官方manbext網頁版|萬博manbext手機|萬博manbetx官網乙醇溶液的主要用途一般是用作鹵代烴發生消去反應,消去反應的定義是:有機化合物砸一定條件下,從一個分子中脫去一個小分子,而生成不飽和化合物的反應。化學實驗上使用萬博官方manbext網頁版|萬博manbext手機|萬博manbetx官網乙醇液進行鹵代烴發生消去反應而不是水溶液是因為乙醇能是溴乙烷充分溶解,而萬博官方manbext網頁版|萬博manbext手機|萬博manbetx官網水溶液反應會朝著水解的方向進行。其消去反應的化學式子為:
The main use of potassium hydroxide ethanol solution is generally used for the elimination reaction of halogenated hydrocarbons. The definition of elimination reaction is: under certain conditions, organic compounds remove a small molecule from a molecule and generate unsaturated compounds. In chemical experiments, potassium hydroxide ethanol solution is used for halogenated hydrocarbon elimination reaction instead of aqueous solution because ethanol can dissolve bromoethane fully, while potassium hydroxide aqueous solution reaction will proceed in the direction of hydrolysis. The chemical formula of the elimination reaction is as follows:
萬博官方manbext網頁版|萬博manbext手機|萬博manbetx官網具有強烈的腐蝕,人體吸入后會強烈刺激呼吸道,造成灼傷,皮膚和眼直接接觸可引起灼傷,口服灼傷消化道,可致死。所以在使用或配置萬博官方manbext網頁版|萬博manbext手機|萬博manbetx官網溶液時需要小心操作,必要時佩戴相應多的防具,以防損傷。
Potassium hydroxide has strong corrosion, which will strongly stimulate the respiratory tract after inhalation, causing burns. Direct contact with skin and eyes can cause burns. Oral burning of digestive tract can cause death. Therefore, in the use or configuration of potassium hydroxide solution need to be careful operation, if necessary, wear corresponding more armor to prevent damage.
