Abstract:
Disclosed herein is a simple process for functionalization/grafting of carbon microspheres obtained from bagasse with various active functional groups onto it and use of the same as catalyst for various organic reactions, having very high selectivity and conversion rate.

Claim (Index 11):
A process for preparation of functionalized carbon microspheres by grafting catalytically active functional groups on to carbon microspheres obtained from bagasse to generate an acidic or basic surface wherein said process comprises the steps of:\n a) heating bagasse, water and oxalic acid at a temperature ranging between 150 to 180\u00b0 C. for a time period ranging between 6 to 12 hours to obtain carbon microspheres; and b) refluxing of carbon microspheres as obtained in step (a) and an organic solvent selected from the group consisting of n-pentane, n-hexane, toluene, and lower alcohols in the presence of a functional group grafting agent at a temperature ranging between 80-120\u00b0 C. for a time period in the range of 8 to 12 hours to obtain functionalized carbon microspheres,\n wherein \n the C\u2014O formation reaction is an epoxidation process which comprises mixing an olefin, an oxidant H 2 O 2 , an organic solvent acetonitrile and amine functionalized carbon microspheres to obtain a reaction mixture followed by immersing the reaction mixture in a thermostat oil bath at a temperature ranging between 60-80\u00b0 C. for a time period ranging between 24 to 48 hours to obtain an epoxide with yield in the range of 45-90%.
