What is potassium hydroxide (KOH) 90% and where is it used?
KOH 90% is a high-purity potassium hydroxide in white flake/pellet form (CAS 1310-58-3). As a strong inorganic base it is used in liquid soap and detergents, potassium salts, fertilizer, biodiesel transesterification and water treatment, and for pH adjustment and neutralization.
What is the difference between 90% KOH flake and 48% KOH solution?
Both are the same substance (CAS 1310-58-3); the difference is the form. KOH 90% is a solid white flake/pellet at higher concentration, which is more efficient to ship and store (UN 1813). KOH 48% is a liquid solution that is easy to dose (UN 1814).
How is 90% KOH stored?
KOH 90% is stored in a cool, dry, well-ventilated area, protected from moisture and atmospheric CO2. Its shelf life is 24 months, and it can be transported by road and sea under UN 1813. It is supplied in 25 kg PE bags and 1000 kg big-bags.
What are the typical purity and impurity values for 90% KOH?
The product contains a minimum of 90% KOH. Typical impurity limits are potassium carbonate (K2CO3) max 0.5%, chloride (Cl) max 0.005%, sodium (Na) max 1.0% and iron (Fe) max 0.0002%. The full specification and a certificate of analysis (CoA) are provided by KORKİMYA on request.
