General description

Potassium hydroxide may be used in the following processes:

Conversion of nitriles to amide in tert-butanol.[4]
Cross-coupling of aryl halides with different sulfur-, oxygen- and nitrogen-based nucleophiles in dimethyl sulfoxide.[5]
As an activator for the preparation of activated carbons from corn cobs.[6]
As a base for the N-alkylation of nitrogen heterocycles in polyethylene glycol-ether solvents.[7]
Synthesis of (S)-1-(4-benzyl-2-thioxothiazolidin-3-yl)propan-1-one from (S)-phenylalaninol.[8]
To catalyze the polymerization of propylene oxide.[9]
