氫氧化鉀在化妝品領域應用較廣，使用時對其質量要求較高。如果里面有很多其他成分，使用時可能達不到預期效果。即使用在化妝品中，對皮膚也是有害的，那么使用時應該如何決定雜質的含量呢。
Potassium hydroxide is widely used in cosmetics, and its quality requirements are high. If there are many other ingredients inside, the expected effect may not be achieved when used. Even when used in cosmetics, it is harmful to the skin, so how should the content of impurities be determined when using it.
1.先用天平稱出準確的樣品重量1.5-2.0g，然后置于250ml燒杯中，加入蒸餾水溶解。溶解完成后，可將其放入相同尺寸的容量瓶中，待水溶解250ml后停止加水。
1. First, use a balance to weigh the accurate sample weight of 1.5-2.0g, then place it in a 250ml beaker and add distilled water to dissolve. After dissolution, put it into a volumetric flask of the same size, and stop adding water when the water is dissolved to 250ml.
2.將溶解液均勻倒入三個錐形瓶中，加入兩滴酚酞指示劑。然后逐滴加入鹽酸溶液，直溶液由紅色變為無色。然后記錄所用鹽酸的體積，并添加2滴甲基橙指示劑。同樣，用鹽酸標準溶液滴定，直到溶液變成橙色。
2. Evenly pour the solution into three conical flasks and add two drops of phenolphthalein indicator. Then add hydrochloric acid solution dropwise until the solution changes from red to colorless. Then record the volume of hydrochloric acid used and add 2 drops of Methyl orange indicator. Similarly, titrate with hydrochloric acid Standard solution until the solution turns orange.
3.然后記錄兩次加入鹽酸溶液的體積，據此計算產品的雜質含量。
3. Then record the volume of hydrochloric acid solution added twice and calculate the impurity content of the product based on this.
現在氫氧化鉀的廠家很多，所以他們之間的競爭也很激烈，所以除了在上做讓步，我們還需要把產品質量做得較好，因為市場上的產品質量參差不齊，所以如果我們的產品質量很高，那么消費者比較愿意購買質量較好的產品現在就讓我們一起來學習如何增加產品的質量。
At present, there are many potassium hydroxide manufacturers, so the competition between them is also very fierce. In addition to making concessions on price, we also need to improve the product quality. Because the product quality in the market is uneven, so if our product quality is very high, then consumers are more willing to buy products with better quality. Now let's learn how to increase the product quality together.
1.當濃縮成片狀燒堿時，加熱過程中一般以熔鹽為介質，熔鹽需要用氫氣燃燒爐獲得熱源。燃燒爐放熱時，需要處于穩定狀態，以保持熔鹽溫度和流量相對平衡。它只有在相對穩定的狀態下才能被加熱。一般情況下，選廠后堿溫需達到380-400℃。
When concentrated into flakes of caustic soda, the heating process usually uses molten salt as the medium, and the molten salt needs to be burned in a hydrogen furnace to obtain a heat source. When the combustion furnace releases heat, it needs to be in a stable state to maintain a relative balance between the molten salt temperature and flow rate. It can only be heated in a relatively stable state. In general, the alkali temperature after plant selection needs to reach 380-400 ℃.
2.加熱時，要控制好高壓蒸汽的壓力和溫度。一般情況下，溫度在190-210℃之間比較適合。
2. When heating, it is necessary to control the pressure and temperature of high-pressure steam. In general, a temperature range of 190-210 ℃ is more suitable.
3.在加熱過程中，需要保持設備處于密封狀態。在高壓加熱過程中，要避開與空氣接觸。
During the heating process, it is necessary to keep the equipment in a sealed state. During high-pressure heating, avoid contact with air.
The key to increase the quality of potassium hydroxide was introduced. During the heating process, the pressure and temperature should be controlled, including no air leakage during the heating process.
