General description
Potassium hydroxide (KOH), also known as caustic potash. It is used as a significant precursor to many potassium containing products.
Application
In combination with tellurium powder, mediates the quantitative pinacolization of aromatic carbonyl compounds.
Potassium hydroxide can be used:
- As a base in the synthesis of imines, starting from amines and alcohols.
- As a base in β-alkylation of secondary alcohols with primary alcohols without any transition metal catalyst.
- In combination with aluminium for pinacolization of aromatic aldehydes and reduction of hindered ketones.
- As a precipitating agent in the synthesis of MnZn ferrites nanoparticles (Mn0.8Zn0.2Fe2O4 ferrite nanoparticles) by modified hydrothermal method.
