Benefits of technology

[0005] Embodiments of the current invention are several methods for preparing lubricant additives and lubricants by reacting together organophosphates and organothiophosphates and their derivatives, such as zinc dialkyldithiophosphate (ZDDP), and fluorine compounds, such as metal fluorides, organoflourides and fluorinating agents. Certain embodiments of the invention comprise methods for preparing lubricant additives by reacting at least one organophosphate compound and at least one fluorinating agent wherein the at least one of the fluorinating agent part

Problems solved by technology

However, many compounds currently in use also have undesirable characteristics.
Phosphorous and sulfur poison catalytic converters causing increased automotive emissions.
However, no acceptable anti-wear additives to replace ZDDP or to modify ZDDP to have more desirable characteristics are currently available.

Embodiment Construction

[0022] Embodiments of the present invention provide low phosphorous lubricants comprising improved lubricant additives. Lubricant additives according to embodiments of the present invention may be added to lubricants including, but not limited to, greases, crankcase oils, and hydrocarbon solvents comprising from about 0.01 weight percent phosphorous to about 0.1 weight percent phosphorous. In a preferred embodiment of the present invention, lubricant additives are mixed with a fully formulated engine oil without ZDDP. The term “fully formulated oil” as used herein to illustrate certain embodiments of the present invention is used to describe engine oils that include additives, but not zinc dialkyldithiophosphate (ZDDP), and comprise from about 0.01 weight percent phosphorous to about 0.1 weight percent phosphorous. In certain embodiments, the fully formulated oil may be, for example, a GF4 oil with an additive package comprising standard additives, such as dispersants, detergents, a...

Abstract

Disclosed are methods for preparing lubricant additives and lubricants by reacting together organophosphate compounds and fluorine compounds, the fluorine compound participating in the reaction as a reactant. The supernatants and precipitates formed during the reaction then may be used as lubricant additives.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] The present application claims priority to U.S. provisional patent application Ser. No. 60 / 511,290 filed on Oct. 15, 2003, entitled “ENGINE OIL ADDITIVE,” and co-pending, commonly assigned, U.S. patent application Ser. No. 10 / 965,686 filed Oct. 14, 2004, entitled “Engine Oil Additive,”, the disclosures of which are hereby incorporated by reference herein.TECHNICAL FIELD [0002] The present application relates generally to lubricants, and more particularly, to synthesis of fluorinated zinc dialkyldithiophosphate (ZDDP). BACKGROUND OF THE INVENTION [0003] Lubricants comprise a variety of compounds selected for desirable characteristics such as anti-wear and anti-friction properties. Many of these compounds are used in enormous quantities. For example, more than four billion quarts of crankcase oil are used in the United States per year. However, many compounds currently in use also have undesirable characteristics. Currently available cran...
