Description
- General description: Potassium hydroxide (KOH, Caustic potash) is a base. It is a water absorbing, colorless solid having rhombic crystals. It has been synthesized by reacting potassium carbonate with calcium hydroxide. It is widely employed for the manufacture of dyes and pigments.[1] Pulverized KOH may be used for the preparation of chalcones.[2]
- Application: Potassium hydroxide (KOH) may be employed for the following studies:As an etching agent for the laser modified silica glass. It selectively facilitates etching on exposure to femtosecond laser.[3]As a catalyst for the transformation of palm oil along with methanol to methyl esters, via transesterification reaction.[4]Preparation of potassium hydroxide catalyst supported on palm shell activated carbon, which is used for the transesterification of palm oil.[5]To improve the catalytic efficacy of X, Y and ZSM (Zeolite Socony Mobil)-5 zeolites during the synthesis of methyl methacrylate.[6]
- Other Notes: Reagent for the decomposition of silicates by fusion[7][8]
