Abstract
Green demulsifiers useful for demulsifying emulsions of water and crude oil are made by reacting together an alcohol, a multifunctional acid and/or anhydride, and a fatty acid, and optionally a polyol that is polyethylene glycol and/or polypropylene glycol. The green demulsifier has ester bonds between the reactant moieties. These ester bonds can hydrolyze which results in relatively high biodegradation.
