Description

Application

• Decomposition of sodium peroxybenzoate in sodium hydroxide solution.: This study investigates the decomposition process of sodium peroxybenzoate in sodium hydroxide solution. The research provides detailed insights into the chemical reactions and kinetics involved, which are essential for understanding the stability and reactivity of peroxy compounds in alkaline solutions (Tetrahedron, 1970).
