## Abstract

The invention relates to butanol compositions for fuel blending and fuel blends comprising such compositions. The compositions and fuel blends of the invention have desirable performance characteristics and can serve as alternatives to ethanol-containing fuel blends. The invention also relates to methods for producing such butanol compositions and fuel blends.
