General description

Potassium hydroxide is an inorganic compound with the chemical formula KOH. It is a strong base and is commonly known as caustic potash. Caustic potash is mainly used for making potassium salts, acid-base titrations, and organic synthesis. Furthermore, KOH can be used as an electrolyte in some fuel cells and alkaline batteries. Potassium hydroxide readily reacts with acids. It is used in various reactions such as nucleophilic, addition, and basic hydrolysis reactions. Additionally, it is employed as a catalyst for aldol-type reactions.

Application

Potassium hydroxide can be used:

To prepare KOH treated powder activated carbon, which is used as a catalyst for the synthesis of CNT (carbon nano tube) using chemical vapor deposition (CVD) method.
As a base in the intramolecular N-arylation of urea′s to form benzimidazol-2-ones.
As a catalyst for the synthesis of khellactone-type compounds (10-aryl substituted-9,10-dihydropyrano[2,3-h] benzopyrone-8-ones) via one-pot, three-component (Meldrum′s acid, aryl aldehydes and 5,7-dihydroxy benzopyrone derivatives) reaction.

Sub-micron silicon nitride waveguide fabrication using conventional optical lithography.

Yuewang Huang et al.

Optics express, 23(5), 6780-6786 (2015-04-04)

We demonstrate a novel technique to fabricate sub-micron silicon nitride waveguides using conventional contact lithography with MEMS-grade photomasks. Potassium hydroxide anisotropic etching of silicon facilitates line reduction and roughness smoothing and is key to the technique. The fabricated waveguides is

A packed bed membrane reactor for production of biodiesel using activated carbon supported catalyst.

Saeid Baroutian et al.

Bioresource technology, 102(2), 1095-1102 (2010-10-05)

In this study, a novel continuous reactor has been developed to produce high quality methyl esters (biodiesel) from palm oil. A microporous TiO2/Al2O3 membrane was packed with potassium hydroxide catalyst supported on palm shell activated carbon. The central composite design
