ABSTRACT:
This invention provides for water-oil emulsions comprising water, oil and a minor emulsifying amount of the reaction product of: (A) at least one saturated or unsaturated aliphatic monocarboxylic acid of about 12 to about 24 carbon atoms; (B) at least one acid of the general formula C.sub.19 H.sub.n COOH, wherein n is a number in the range of about 27 to about 31, and having a phenathrene nucleus; and (C) at least one amine. In one hydroxy embodiment, the oil employed in these emulsions can be any oil, the water content of these emulsions being up to about 30% by weight. In a preferred embodiment, the oil employed is crude oil. These emulsions can be facilitatingly pumped through a conduit even when the oil employed is a viscous crude oil. These emulsions are useful as a combustible fuel when the water content is below about 30% by weight.
