Potassium Hydroxide 98.5% CAS 1310-58-3

Chemical Properties: Potassium hydroxide, also known as caustic potash, is an inorganic compound with the chemical formula KOH. It is a strong base and is highly corrosive.

Concentration: At 98.5% concentration, potassium hydroxide is considered a concentrated solution, and it should be handled with care due to its corrosive nature.

Solubility: Potassium hydroxide is highly soluble in water, and solutions of various concentrations can be easily prepared.

Alkalinity: Being a strong base, potassium hydroxide solutions are highly alkaline, with pH values typically ranging from 12 to 14.

Industrial Applications:

• Chemical Manufacturing: Potassium hydroxide is used in the production of numerous chemicals, including potassium carbonate, potassium phosphates, potassium silicates, and potassium soaps.
• Fertilizer Production: It is employed in the manufacturing of potassium-containing fertilizers, which are essential for plant growth and nutrition.
• Soap and Detergent Manufacturing: Potassium hydroxide is a key ingredient in the production of liquid soaps and detergents. It reacts with fats and oils through saponification to form potassium salts of fatty acids (potassium soaps).
• Petroleum Industry: It is used in refining processes to remove impurities and contaminants from petroleum products.
• Food Industry: Potassium hydroxide is utilized in the food industry for various purposes, including pH adjustment, food processing, and the production of certain food additives.
• Biodiesel Production: It is used in the transesterification process to convert vegetable oils or animal fats into biodiesel fuel.
• Textile Industry: Potassium hydroxide is used in textile processing for mercerization, a treatment that improves the luster, strength, and dyeability of cotton fibers.
• Electroplating: It is used in electroplating processes to prepare surfaces for plating by removing contaminants and providing a clean substrate.
• Water Treatment: Potassium hydroxide is used in water treatment applications for pH adjustment and neutralization of acidic water.

Safety Considerations:

• Due to its corrosive nature, potassium hydroxide should be handled with caution. Direct contact with skin, eyes, or mucous membranes can cause severe burns and tissue damage.
• Protective equipment, including gloves, goggles, and suitable clothing, should be worn when handling potassium hydroxide solutions.
• Proper ventilation is necessary when working with potassium hydroxide to prevent inhalation of fumes and vapors.
• Spills should be promptly cleaned up using appropriate neutralizing agents and procedures.
• Storage containers should be tightly sealed and kept away from incompatible materials.
