Abstract
A process for blending isopropanol from an aqueous solution of isopropanol directly into a stream of gasoline blending hydrocarbons which comprises mixing the aqueous solution with the gasoline blending hydrocarbons, allowing the mixture to separate into two phases and recovering an organic phase which consists essentially of the gasoline blending hydrocarbon and the isopropanol.
Claims4
A process for blending isopropanol from an aqueous isopropanol solution into gasoline comprising the steps of:
- (a) mixing at atmospheric pressure an aqueous solution of isopropanol having an isopropanol content of greater than about 50% with gasoline at a volume ratio of gasoline to isopropanol solution of at least 2:1;
- (b) allowing the mixture to separate into two phases, an organic phase which consists essentially of the gasoline and the isopropanol and an aqueous phase which consists essentially of water;
- and
- (c) recovering the organic phase.
