一乙醇胺通常用電解氯化鉀溶液，或將碳酸鉀和石灰乳反應而得，用于制取鉀鹽和鉀肥皂，還可作干燥劑等，由電解濃氯化鉀溶液或以碳酸鉀與石灰乳作用而制得，用作干燥劑、吸收劑，用于制草酸及各種鉀鹽，
Monoethanolamine is usually obtained by electrolytic potassium chloride solution or by reacting potassium carbonate with lime milk. It is used to prepare potassium salt and potassium soap. It can also be used as desiccant. It is prepared by electrolytic concentrated potassium chloride solution or by the action of potassium carbonate and lime milk. It is used as desiccant and absorbent for the preparation of oxalic acid and various potassium salts,
氫氧化鉀精制過的1，4‐二氧環(huán)己烷應當避免與空氣接觸，進一步氯化,可得CHCl3和CCl4，無色易揮發(fā)液體，難燃燒，蒸氣與空氣形成爆炸性混合物,爆炸極限6，對皮膚和粘膜的刺激性比氯仿稍強,使用高濃度二氯甲烷時應注意。

1,4-dioxane refined by potassium hydroxide should avoid contact with air and be further chlorinated to obtain CHCl3 and CCl4. It is colorless, volatile liquid and difficult to burn. The vapor forms an explosive mixture with air. The explosion limit is 6. It is slightly more irritating to skin and mucous membrane than chloroform. Attention should be paid when using high concentration dichloromethane.

氫氧化鉀當聚合氯化鋁絮凝劑和聚丙烯酰胺進行配合使用的時候，我們應視不同的水質按照先后順序投加，而其藥量也要通過試驗確定，其實，聚合氧化鋁也可以單用，但其價格比PAC高，效果不比加PAC的水質差，當然要分水質情況而定。
When potassium hydroxide is used in combination with polyaluminium chloride flocculant and polyacrylamide, we should add it in order according to different water quality, and its dosage should also be determined through experiments. In fact, polyaluminum oxide can also be used alone, but its price is higher than PAC, and the effect is not worse than that of PAC. Of course, it depends on the water quality.
