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]
