Patent
·
OSTI ID:5163972
This patent describes a process of demulsifying an oil-in-water emulsion which comprises admixing with the emulsion a water-soluble polymer of monoallylamine that causes formation of and separation between an oil phase and an aqueous phase to occur. The emulsion has a pH in the range of about 5 to about 10 and the polymer has a weight average molecular weight of at least 1000 and contains at least 95% by weight of monoallylamine.
