Abstract
|
In recent years, green chemistry has focused mainly on environmentally friendly reactions, sustainable resources and reusable catalysts. Ionic liquids (ILs) have attracted extensive research interest as environmentally benign solvents due to their excellent properties such as negligible vapor pressure, solvating ability and non-flammability 1. Compared to pure acidic ILs, IL-based heterogeneous catalysts offer more advantages. They are required in small amounts, are easy to separate and have a competent catalyst recovery 2. The immobilization process aims to transfer the desired catalytic properties of the liquids to a solid catalyst. Cellulose is the most abundant renewable bio-macromolecule in the nature which is widely produced in industrial scale. It has properties including biodegradability and non-toxicity which make it superior support for catalytic applications over conventional organic or inorganic ones.
