Title: COMPOSITIONS AND METHODS FOR SEPARATING IMMISCIBLE LIQUIDS
Abstract:
Provided are methods and related compositions for separating immiscible organic and aqueous compositions. The methods include dispersing a discrete, insoluble filler in the organic composition, dispersing the organic composition into the aqueous composition, separating under gravity the organic and aqueous compositions into respective upper and lower layers. Advantageously, the insoluble filler remains in the organic composition and facilitates segregation and coalescence of droplets of the organic composition in the aqueous composition.
