"The patent text describes an improved emulsifier and detergent composition for metalworking lubricants. The emulsifier is made by co-sulfonating selected alkylbenzenes and olefins with oleum. This composition can be used in soluble oils and straight oils, which are the main types of metalworking fluids used in the industry. The emulsifier helps to stabilize the oil in water emulsion, which is the key to the success of soluble oil formulations. The invention also provides a hydrocarbon oil-free formulation for those who want to avoid the use of chlorinated and active sulfur compounds. The emulsifier can be used with synthetic oils or fluids to provide a hydrocarbon-free formulation. The invention also addresses the issue of disposal by allowing the oil portion of the metalworking fluid to separate out and be easily removed. The emulsifier described in the patent text can be used in both soluble oils and straight oils."

example
[0086] Outline of Method—The heptane sulfonic acid from the above procedure is neutralized with sodium hydroxide. The neutralized reaction mass is settled and the brine layer is removed. The neutral sodium sulfonate solution is then heated and the heptane is removed via distillation. This procedure yields a product of this invention, a sodium sulfonate.
[0087] Procedure—A known, measured and analyzed amount of heptane sulfonic acid solution is charged to a suitable vessel. Mixing is begun and water and / or methanol is added to the sulfonic acid mixture. The amount of water required is approximately five percent (5%) based upon the weight of the heptane sulfonic acid charged. Mixing is continued for 15 minutes after the water addition and, then the acid is neutralized with sodium hydroxide / water solution. The concentration of the sodium hydroxide solution is not critical and concentrations up to 50 percent (50%) sodium hydroxide can be utilized. The amount of sodium h...

Abstract
Metal sulfonate emulsifier and detergent compounds for use with various metalworking lubricants are taught together with the method of preparing same. The sulfonates are prepared by co-sulfonating selected alkylbenzenes and certain oils with oleum. More specifically, the method involves preparation of a complex mixture of alkylbenzenes and lubricating oils, sulfonation by means of oleum only, and conversion to a metal sulfonate via specific processing steps.
Description
RELATED APPLICATIONS [0001] This patent application is claiming the benefit of the U.S. Provisional Application No. 60 / 508760, filed Oct. 3, 2003, and entitled Emulsifier / Detergent Compounds for Metalworking Lubricants.FIELD OF THE INVENTION [0002] The subject invention relates generally to metalworking lubricant additives, and more specifically to improved emulsifier and detergent compositions prepared by co-sulfonating selected alkylbenzenes and oils with oleum. BACKGROUND OF THE INVENTION [0003] Metalworking continues to be a major industry throughout the world. During a metalworking operation, the metal in question may be forged, rolled, stamped, cut, formed or ground. Almost all metal objects from the smallest screws to large beams have been processed with at least one metalworking operation. [0004] Successful metalworking requires the use of good fluids which can function both as a lubricant and a coolant. These lubricants and coolants are derived from a number of different ty...
