McCoy, D R; McEntire, E E

A process for recovering bitumen from oil-in-water (O/W) emulsions is disclosed wherein water-soluble demulsifiers are used. These demulsifiers are ionenes prepared generally by reaction of ditertiary amines and dihalides. To resolve the bituminous petroleum emulsions, the process is carried out between 25/sup 0/ and 160/sup 0/C wherein the demulsifier of the invention is contacted with the bituminous emulsion.
