Abstract
There is disclosed a process for hydroformylation of carbon black. The carbon black is hydroformylated by reacting carbon black with carbon monoxide and hydrogen under hydroformylation conditions in the presence of a hydroformylation catalyst and organic reaction solvent. Addition of the hydroformylated carbon black enhances the rates of cure of sulfur vulcanizable rubber.
