High-performance diesel fuel lubricity additive

摘要

The present teachings are directed toward the invention of high-performance diesel fuel lubricity additives that are comprised of a mixture of one or more C3-C10 di-carboxylic acids with a mixture of one or more C3-C14 carboxylic acids that are blended in one or more C3-C16 hydroxy-alkanes. These additives may be produced by blending one or more C3-C14 carboxylic acids, C3-C10 di-carboxylic acids and C3-C16 hydroxy-alkanes, or by using various chemical synthesis procedures to directly produce mixtures of these classes of oxygenated aliphatic hydrocarbons.

1. A high performance diesel fuel additive formulation, which consists essentially of a mixture of one or more C3-C10 di-carboxylic acids and one or more C3-C14 carboxylic acids dissolved in a mixture of one or more C3-C16 hydroxy-alkanes, wherein the alkane of the hydroxyl-alkanes is non-branched or branched, and wherein the C3-C16 hydroxy-alkanes react with a carboxylic acid group on the C3-C10 di-carboxylic acids to form esters under high temperature conditions in a diesel engine.
