Metal-bipyridine supported on 3-aminopropyl-functionalized MK10: effect of a metalating agent on the catalytic activity in the transesterification of β-keto ester.

ABSTRACT: The grafting of metal-bipyridine (Bpy-M, M = Mn or Zn) on aminopropyl-modified montmorillonite K10 (NH2-MK10) synthesized via a functionalization-immobilization-metalation route was investigated. Formulated NH2-MK10-Bpy-Mn and NH2-MK10-Bpy-Zn were characterized using BET, FTIR, SEM, XRD, CHNS and NH3-TPD techniques and tested for the synthesis of butyl acetoacetate (BAT) via the transesterification of β-keto ethyl acetoacetate (EAA) with butanol (BTL). The influence of reaction parameters on the BAT yield was investigated using the Taguchi optimization approach. According to characterization data, the samples were mesoporous materials with a considerable number of acidic sites and diverse inorganic and organic functional groups, making them inorganic-organic hybrid catalysts.
