Abstract:
1. An emulsified water-blended fuel composition comprising: (A) a hydrocarbon boiling in the gasoline or diesel range: (B) water; (C) a minor emulsifying amount of at least one fuel-soluble carboxylic salt made by reacting (C)(I) at least one acylating agent having about 16 to about 500 carbon atoms with (C)(II) ammonia and/or at least one amine, the acylating agent containing at least one hydrocarbyl substituent group and at least on succinic group and being characterized by the presence within its structure of at least about 1.3 succinic groups for each equivalent weight of the hydrocarbyl substituent; and (D) a minor emulsion stabilizing amount in the rang of about 0.001 to about 15% by the weight of said water-blended fuel composition of water-soluble amine salt represented by the formula wherein in formula (D-I), G is hydrogen, or an organic neutral radical of 1 to about 8 carbon atoms having a valence of y; each R independently is hydrogen or a hydrocarbyl group of 1 to about 10 carbon atoms; X p− is an anion having a valence of p; and k, y, n, and p are independently at least 1, provided that when G is H, y is 1; further provided that either G or at least one R is hydrogen; and further provided that the sum of the positive charge ky + is equal to the sum of the negative charge np − such that the amine salt (D) is electrically neutral.
