Recovery of Wilkinson's Catalyst from Hydrogenated Nitrile Butadiene Rubber Latex Nanoparticles

摘要

Three different chelating ligands were used to separate Wilkinson's catalyst from HNBR nanoparticles in latices. N,N,N',N',N ''-pentamethyldiethylenetriamine was found to be very effective in removing the catalyst. HNBR particle size and the extraction temperature on catalyst removal were investigated. The mechanism involved in the separation process was elucidated. This study promotes the possible commercialization of the green latex direct hydrogenation technique.
