DESCRIPTION
General description
Potassium hydroxide, also known as caustic potash, is a water soluble strong base. The electron scattering in KOH has been investigated.[1] Its infrared spectrum has been recorded and analyzed.[2] The impact of surface functionalization of active carbons using KOH has been studied.[3] Its role as a catalyst in the Michael addition reaction has been explored.[4]
Application
Potassium hydroxide (KOH) has been used to prepare methanolic-KOH that is employed in a protocol for saponification of fruit extracts.[5]
KOH has been used for adjusting pH during the preparation of the following:[6]
