Abstract: The invention relates to an improved process for producing organomolybdenum compositions with high molybdenum content that are highly useful as lubricant additives, in which the process involves reacting a fatty oil with a diamine, followed by reaction with a molybdenum source. The process of the present invention does not require a volatile organic solvent to promote molybdenum incorporation and produces an organomolybdenum composition having a high molybdenum content. In addition, the process can be conducted in the absence of sulfur and phosphorus-containing reactants.
Abstract: The invention relates to a lubricating oil composition having improved antioxidant properties, and which contains a molybdenum compound and an alkylated phenothiazine. Further, it may also include a secondary diarylamine, preferably an alkylated diphenylamine. This combination of additives provides improved oxidation control and friction modifier performance to the lubricating oil. The composition is particularly suited for use as a crankcase lubricant, or a transmission lubricant, including low levels and zero levels of phosphorus.

Abstract: A friction modifier for combustible fuels is provided that is prepared by combining a saturated carboxylic acid and an alkylated amine. Furthermore, there also is an additive concentrate for use in fuels, especially in gasoline for internal combustion engines, comprising (a) a friction modifier comprising of a branched saturated carboxylic acid salt of an alkylated amine, such as n-butylamine isostearate; (b) a detergent package, as well as the combustible fuels containing this additive concentrate. The particular selection of friction modifier (a) enables a stable additive concentrate to be formulated providing a significant benefit in friction loss when incorporated in gasoline used to fuel an internal combustion engine, and hence an improvement in fuel economy.

Abstract: This invention relates to a low cost, wear inhibitor containing novel dithiocarbamates with alkylthio and hydroxy substituents that can be used to formulate low phosphorus lubricants. In addition to wear inhibition, the dithiocarbamate compositions of the invention provide substantial oxidation protection to lubricating oils and are not detrimental to fuel economy.
Abstract: Gear oils meeting GL-5 specifications are obtained by blending a base oil, a thermally stable phosphorus-containing anti-wear agent; and a metal-free sulfur-containing extreme-pressure agent; wherein the thermally stable phosphorus-containing anti-wear agent is present in an amount sufficient to provide from 100 to 350 ppm phosphorus to the formulated gear oil and wherein the metal-free sulfur-containing extreme-pressure agent is present in an amount sufficient to provide at least 10,000 ppm sulfur to the formulated gear oil and wherein the formulated gear oil contains 350 ppm of phosphorus or less.

Abstract: The present invention relates to an apparatus and method for delivering molybdenum from a lubricant source into a fuel combustion system or to the exhaust therefrom. By the present invention, molybdenum from the lubricant or the fuel will interact with phosphorus, sulfur, and/or lead from the combustion products. In this manner, the molybdenum scavenges or inactivates harmful materials which have migrated into the fuel or combustion products, and which can otherwise poison catalytic converters, sensors and/or automotive on-board diagnostic devices. The present invention can also lead to improved durability of exhaust after treatment systems.

Abstract: The present invention provides a low sulfur, low ash, and low phosphorus oil soluble lubricant additive package comprising an overbased metal phenate. Also included in the present invention are lubricating oils comprising the inventive oil soluble lubricant additive package, as well as machines lubricated by such oils. Several methods for lubricating machinery are also disclosed.
Abstract: New, highly effective detergent/dispersants for use in spark-ignition fuels comprising Mannich condensation products formed from (i) at least one substituted hydroxyaromatic compound having on the ring both (a) an aliphatic hydrocarbyl substituent derived from a polyolefin having a number average molecular weight in the range of about 500 to about 3000, and (b) a C1-4 (ii) at least one secondary amine; and (iii) at least one aldehyde are described. Carrier such as ploy(oxyalkylene) compounds further enhance the effectiveness of these Mannich condensation products in minimizing or reducing intake valve deposits and/or intake valve sticking.

Abstract: A process for the prediction and the optimization of the output of a plant producing products form incoming materials. The incoming materials are classified according to various physical characteristics and costs. The desired or ordered products are also classified according to price and physical requirements. The incoming materials information and the product information is entered into a database which is accessible by a computing device. The computing device then calculates the optimal production process by calculating a plurality of production cycles and selecting the cycle with the optimum profitability. The computing device is programmed with non-linear equations derived from a regressive analysis of data collected from samples of incoming materials and products.
