Description
General description
Potassium hydroxide is an inorganic salt mainly used as a precursor to
synthesize other potassium compounds such as potassium acetate,[7] potassium
bicarbonate and potassium carbonate.[8] On
a commercial scale, it is synthesized by the electrolysis of potassium
chloride.[9]
Application
Potassium hydroxide may be used in the following processes:
• Conversion of nitriles to amide in tert-butanol.[10]
• Cross-coupling of aryl halides with different sulfur-, oxygen- and
nitrogen-based nucleophiles in dimethyl sulfoxide.[11]
• As an activator for the preparation of activated carbons from corn cobs.[12]
• As a base for the N-alkylation of nitrogen heterocycles in
polyethylene glycol-ether solvents.[13]
• Synthesis of (S)-1-(4-benzyl-2-thioxothiazolidin-3-yl)propan-1-one
from (S)-phenylalaninol.[14]
• To catalyze the polymerization of propylene oxide.[15]
