| Abstract: | The super alcohol absorbing resin beads,with large particle size(larger than 3 mm),was synthesized by inverse suspension polymerization using hydrochloride of N,N′-dimethylaminoethyl methacrylate(DM)and acrylamide (AM)as monomers.The absorption ability of the resin reaches more than 30 g/g for methanol.The optimun amounts of dispersing agent(Span60),initiator (K 2S 2O 8),cross linking agent and monomer used are 0 25 g/100 ml cyclohexane,0 4% by weight in total monomer,0 15% by weight in total monomer and 40% (by weight in liquid phase) respectively. |
