Description

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.
