Preparation and Characterization of Anion Exchangers from Petroleum Asphaltites

摘要

The chloromethylation reaction of an asphaltite and styrene graft copolymer followed by the ami-nation of the chloromethylated products was optimized. New strongly basic anion exchangers with an exchange capacity of 2.5 mg-equiv/g and a mechanical strength of 93% were prepared.
