A microcrystalline cellulose/manganese schiff base complex as a novel eco-friendly biocomposite for oxidation of alcohols

Synthesis and uses of natural polymers as catalysts for the preparation of novel compounds has received steadily increasing attention over the past few years [1]. High demands are placed on the identification of new biocatalysts for organic synthesis. The catalysis of more ambitious reactions reflects the high expectations of this field of research. In this study, cellulose polymer plays an increasingly important role as biocatalysts in the oxidation of alcohols, and new catalyst for green chemistry process have been established [2]. In this work, design, preparation and development of a cellulose/manganese 2- hydroxy-5-methyl benzaldehyde Schiff base biocomposite as a biocompatible, recyclable and highly efficient heterogeneous biocatalyst is explained. This novel biocatalyst was characterized by Fourier transform infrared (FT-IR) spectroscopy, field-emission scanning electron microscopy (FE-SEM) image, energy dispersive Xray (EDX) analysis and thermogravimetric analysis/differential thermal analysis (TGA/DTA). Then, its activity was investigated in the oxidation of alcohols. The main advantages of this clean system are high yields and short reaction times.
