说明

一般描述

Potassium hydroxide (KOH), also known as caustic potash. It is used as a significant precursor to many potassium containing products.

应用

与碲粉结合，介导芳香族羰基化合物的吡那酮化反应。[1]

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.
