Description générale

Potassium hydroxide is an inorganic salt mainly used as a precursor to synthesize other potassium compounds such as potassium acetate, potassium bicarbonate and potassium carbonate. On a commercial scale, it is synthesized by the electrolysis of potassium chloride.

Application

Redi-Dri™ is an innovative packaging product line that helps eliminate clumping material by adding extra packaging process steps without any chemical additives, anti-clumping agents, or hydrophobic compounds. Redi-Dri™ offers a more convenient and safer way to handle the products.
Potassium hydroxide may be used in the following processes:
  • Conversion of nitriles to amide in tert-butanol.
  • Cross-coupling of aryl halides with different sulfur-, oxygen- and nitrogen-based nucleophiles in dimethyl sulfoxide.
  • As an activator for the preparation of activated carbons from corn cobs.
  • As a base for the N-alkylation of nitrogen heterocycles in polyethylene glycol-ether solvents.
  • Synthesis of (S)-1-(4-benzyl-2-thioxothiazolidin-3-yl)propan-1-one from (S)-phenylalaninol.
  • To catalyze the polymerization of propylene oxide.
