Abstract

Stable diesel fuel emulsions of the water-in-oil type comprising from about 97 to about 90 volume percent of a mixture of a major amount of usual diesel fuel and a minor amount of at least about 5 volume percent of an aqueous solution of methanol, ethanol or a mixture thereof, and from about 3 to about 10 volume percent of an emulsifying blend of sorbitan monooleate and a water soluble, ethoxylated, non-ionic surfactant; and a process for producing such stable emulsions comprising adding while stirring the aqueous alcohol solution to a mixture of diesel fuel and emulsifying blend.
