摘要: Abstract Oxidation of propan-2-ol to acetone was carried out in aqueous media at room temperature. The effect promoter (PA, bpy, phen), micellar catalyst (SDS, CPC, TX-100) and their combination has been studied. reactions were performed under the condition [Propan-2-ol]T ≫ [Cr(VI)]T 30 °C. Then kobs half life all reaction determined identify which are most effective for this oxidation. Among promoters phen accelerates media. In absence anionic surfactant SDS increases rate more effectively than neutral TX-100. CPC retards comparison oxidation is highest presence bpy SDS.
