WebIf your product is stable and relatively-non polar, a good way of removing triphenylphosphine oxide is to concentrate the reaction mixture to a lower follow, suspend the residue in pentane (or hexane)/ether and filter over a silica plug. The compound can then be eluted with ether, leaving most of the phosphine oxide at the top of the column.
