Potassium Hydroxide

Potassium Hydroxide 

Chemical Formula: KOH

CAS Number: 1310-58-3

Appearance: White flake, granular or lump solid

Main Characteristics

It is a strong alkaline substance (the pH value of the solution is about 14), and its alkalinity is stronger than that of sodium hydroxide.

It is highly soluble in water and releases a large amount of heat during dissolution.

It has strong hygroscopicity: it will absorb moisture and deliquesce when exposed to air.

It has strong corrosiveness: it is highly corrosive to skin, eyes and metals.

Reaction with acids: It reacts with acids to form corresponding potassium salts and water.

Main Applications

Chemical Production:

Manufacture of potassium soaps, detergents and surfactants.

Raw material for the production of potassium salts such as potassium carbonate and potassium dihydrogen phosphate.

Battery Industry:

Electrolyte for alkaline batteries.

An important raw material for fuel cells.

Food Processing:

As a food additive (acidity regulator).

Cocoa processing and olive treatment.

Agricultural Uses:

Raw material for potassium fertilizers.

Adjust the pH value of soil.

Other Industries:

Treatment of acidic gases in petroleum refining.

Catalyst for biodiesel production.

Safety and Operation

Storage: It must be stored sealed in a dry, cool and ventilated place.

Protective Measures:Wear corrosion-resistant gloves, goggles and protective clothing during operation.

Avoid contact with active metals such as aluminum and zinc (flammable hydrogen will be produced).

Transportation Specifications:

Solid: UN 1813, Class 8 (Corrosive Substance)

Liquid: UN 1814, Class 8

Precautions

First Aid Measures:

Skin Contact: Immediately rinse with plenty of water for more than 15 minutes.

Eye Contact: Immediately rinse with saline or water and seek medical attention.

Environmental Treatment:

The waste solution should be neutralized with acid to neutrality before discharge.
