Deozidation Reaction of Alkali Lignin and Cyclohezene Catalyzed by Pd/C Catalyst
Introduction Lignin is a three-dimensional amorphous biopolymer composed of phenylpropanoid units linked together by ether and carbon-carbon bonds. Depending on the tree species, lignin constitutes 15-35 % of the wood. it exists between the fibre cells and acts, besides other functions, as a cementing material thus imparting rigidity to the wood structure. It is considered to be one of the most promising future organic resources not only because it is renewable, but also is second only to cellulose in abundance among the naturally occurring polymers. Despite many attempts in the past to utilize lignin, the only commercial application of lignin today is in the form of lignosulphonate, which are water-soluble. These modified lignins are primarily employed as agents for binding, dispersion and emulsion stabilization in a variety of industries. The present work focused on improving the reactivity of alkali lignin through reductive reaction of alkali lignin and cyclohexene catalyzing by Pd/C catalyst.
