ABSTRACT:
A process is provided for separating alkyl carbonate from a feedstock comprising at least one alkyl carbonate and at least 0.01 percent by weight water comprising extracting the alkyl carbonate from the feedstock in a liquid-liquid extraction step comprising an extraction solvent selective for extracting alkyl carbonates relative to water in an amount sufficient to extract a substantial amount of the alkyl carbonates from the feedstock. The extraction solvent substantially comprises hydrocarbon boiling at a temperature ranging from about 50.degree. F. to about 700.degree. F. at atmospheric pressure and having a specific gravity ranging from about 0.50 to about 1.00.
