Abstract
A combustion improving additive for liquid fuel consisting essentially of an iron complex soluble in organic media, formed by reacting a sulfonic acid with ferric hydroxide in such proportions as to obtain a ratio of the number of acid gram-equivalents of the sulfonic acid to the number of gram-atoms of the iron in the range from 1/6 to 1/12, said reaction being conducted in the presence of a light aromatic hydrocarbon or a light halogenated aliphatic hydrocarbon having a boiling point from 80.degree. to 230.degree. C. and of an organic liquid containing oxygen, at least partially miscible with water and substantially miscible with hydrocarbons, said complex being obtained in the organic phase of the reaction product.
