Oxidized Carbon Black as an Activator of Transesterification Reactions under Solvent-Free Conditions

[Image: see text] A metal-free procedure for oxidation of carbon black (CB), under mild and ecofriendly conditions, is described. The procedure, based on 5/1 w/w H(2)O(2)/H(2)SO(4), when applied to high-surface-area CB, leads to oxidation contents (O/C = 0.66) comparable to those obtained for graphi...

description [Image: see text] A metal-free procedure for oxidation of carbon black (CB), under mild and ecofriendly conditions, is described. The procedure, based on 5/1 w/w H(2)O(2)/H(2)SO(4), when applied to high-surface-area CB, leads to oxidation contents (O/C = 0.66) comparable to those obtained for graphite with the more aggressive and metal-based Hummers method (O/C 0.63). Oxidized nanocarbons are able to activate transesterification reactions under solvent-free conditions. Activation of transesterification reactions is much more effective by oxidized CB than by graphene oxide.
