Abstract:
An aqueous fuel composition comprising:a continuous phase of a normally liquid hydrocarbon fuel; a discontinuous aqueous phase, said discontinuous aqueous phase being comprised of aqueous droplets having a mean diameter of 1.0 micron or less; and an emulsifying amount of an emulsifier composition comprising (i) a hydrocarbon fuel-soluble product; and optionally (ii) an ionic or a nonionic compound having a hydrophilic lipophilic balance of about 1 to about 10; in combination with (iii) an emulsion stabilizing and combustion improving amount of a water-soluble salt distinct from (i) and (ii); wherein said hydrocarbon fuel-soluble product (i) is a salt comprised of (I) a first polycarboxylic acylating agent, said first polycarboxylic acylating agent having at least one hydrocarbyl substituent of about 20 to about 500 carbon atoms, (II) a second polycarboxylic acylating agent, said second polycarboxylic acylating agent optionally having at least one hydrocarbyl substituent of up to about 500 carbon atoms, said polycarboxylic acylating agents (I) and (II) being coupled together by (III) a linking group derived from a linking compound having two or more primary amino groups, two or more secondary amino groups, at least one primary amino group and at least one secondary amino group, at least two hydroxyl groups, or at least one primary or secondary amino group and at least one hydroxyl group, said polycarboxylic acylating agents (I) and (II) forming a salt with (IV) ammonia or an amine.
