The use of microporous coordination polymers with coordinatively unsaturated metal centers in the removal of dimethyl ether from Chloromethane via flow was explored as an alternative to current industrial methods. Three different materials examined, Co/DOBDC, MIL-100(Fe), and HKUST-1, were able to efficiently purify chloromethane through selective adsorption Of dimethyl ether. The recyclability of Co/DOBDC after separation was also examined, and little loss of capacity for dimethyl ether over the course of multiple regeneration cycles was Observed.
