摘要: Divinyl benzene (DVB), ethyleneglycoldimethacrylate (EGDMA) and NN′-methylenebis-acrylamide (NN′-MBA) cross-linked poly(methyl methacrylate)(PMMA)-supported pyrazolinium chromate, chlorochromate pyrazole-CrO3 complex resins, were prepared used as oxidising reagents for alcohols. These resins selectively oxidise primary alcohols to aldehydes secondary ketones. They possess the desired characteristics of polymeric reagents, including operational simplicity, filterability regenerability. NN′-MBA crosslinked methacrylate)-supported Cr(VI) are more efficient in terms functional group capacity, reaction time product yield.
