PH Adjustment Potassium Hydroxide 90% Purity Cas 1310-58-3

Potassium Hydroxide The Ultimate Solution for pH Adjustment and Surface Charge Increase

Potassium hydroxide, also known as "caustic potassium", has the chemical formula KOH. It is a common strong alkaline inorganic compound, often in the form of white flakes. It is easily soluble in water and ethanol, releases strong heat during dissolution, and easily absorbs moisture and carbon dioxide from the air.
Used as an analytical reagent in chemical industries such as soap making, papermaking, textiles, printing and dyeing, pharmaceuticals, electroplating, and organic synthesis.

Adding potassium hydroxide to the latex system can form a hydrophilic protective layer on the surface of the latex particles, increase the degree of hydration, and improve the mechanical stability of the latex; Potassium hydroxide can be used to adjust the pH value of latex and increase the surface charge of particles.
2. Extracting humic acid from coal using potassium hydroxide
3. Promote the growth of non van der Waals two-dimensional materials
(1) OH - can effectively reduce the binding energy between the material and the substrate surface, making the substrate more conducive to material epitaxial growth, thereby growing two-dimensional materials with larger lateral dimensions; And OH - can reduce the binding energy between the interior of the material, which is beneficial for the growth of thin layers of the material.
(2) K+can passivate the edges of crystals, thereby promoting the growth of materials into regular two-dimensional nanosheets.
4. Preparation of formic acid
(1) Formic acid potassium hydroxide method
Due to the wide source and low price of potassium hydroxide, the formic acid potassium hydroxide method has become the mainstream method for preparing potassium formate in China. However, this process route has low reaction yield, intense exothermic reaction, and difficult process control.
(2) Methyl formate potassium hydroxide method
In recent years, there have been few cases of using methyl formate hydrolysis method, but it can be combined with potassium hydroxide method to prepare potassium formate, which is suitable for industrialization. However, due to the fact that the production of formic acid in China still relies mainly on the sodium formate method, and there are not many cases of using the methyl formate hydrolysis method, the promotion of this method in China still needs time.
5. Preparation of cholesterol by saponification of lanolin
Ethanol is used as the solvent, potassium hydroxide is used as the raw material, and cholesterol can be obtained by separating and purifying the saponification product.
6. Activating agent
Using potassium hydroxide as an activator, porous materials were prepared from high sulfur coal and applied to lithium sulfur batteries. Potassium hydroxide alkaline etching is used to remove some aluminum from hydrotalcite and adsorb carbon dioxide.
7. Other
Potassium hydroxide is a component of chemical reagents used in the display panel industry, including developing solutions, etching solutions, cleaning solutions, and stripping solutions. Potassium hydroxide is the most commonly used alkaline wet electronic chemical in the manufacturing of solar cells. Potassium hydroxide, as one of the most common food additives, mainly plays a role in regulating the pH value of food and maintaining its appearance and form.
