The effects of normal aliphatie alcohols (C₂-C₇) on the demulsifibility of five demulsifiers (block eopolymers of polyoxyethylene and polyoxypropylene) for O/W type emulsion have been studied. The results show that the addition of alcohols (2.5vol.%) greatly enhances the demulsification, and n-butyl and n-amyl alcohols are found to be the most effective.
