Abstract: A mixture including a thiophosphoric acid product suitable for preparing organometallic and/or ashless antiwear additives having improved copper corrosion performance. The thiophosphoric acid product is distilled and recovered as a condensate of the distillation and having a low level of active sulfur.

Abstract: An oil-soluble ashless antiwear additive and a lubricating composition including the ashless antiwear additive having improved copper corrosion performance obtained by reacting an organic hydroxy compound with phosphorus pentasulfide to form a reaction product, distilling the reaction product and recovering a condensate, and reacting the condensate with an unsaturated carboxylic acid to form an oil-soluble phosphorus antiwear additive.

Abstract: High temperature antioxidant additives and methods that improve a liquid fuel composition's thermal oxidative stability are disclosed. A liquid fuel composition may comprise a liquid fuel and a high temperature antioxidant additive. The high temperature antioxidant additive may comprise an indoline compound with a bicyclic ring structure, wherein the indoline compound comprises a six-membered aromatic ring and a five-membered aliphatic ring that share a carbon-carbon aromatic bond. The five-membered aliphatic ring may be heterocyclic and may comprise a nitrogen positioned in an alpha position to the six-membered aromatic ring.

Abstract: Aviation gasolines and additives may have manganese-containing anti-knock components. The scavengers herein mitigate the possible deleterious effects from using the manganese-containing anti-knock. The scavengers include molecules with a central atom of a Group 15 element other than nitrogen. Entities that are attached to the central atom are electron withdrawing entities including electron deficient atoms and electron deficient functional groups.

Abstract: Described herein are modified fuels with improved properties. The modified fuels are more efficient when compared to conventional fuels such as gasoline. Additionally, the modified fuels burn more efficiently and produce fewer emissions. Finally, the modified fuels also do not require any modifications to existing engines.

Abstract: Systems and methods for processing glycerol into one or more products are provided. In at least one specific embodiment, the method can include decreasing a pH of a mixture comprising glycerol and fatty acids to produce an emulsion comprising a glycerol-rich portion and a fatty acids-rich portion. At least a portion of the glycerol-rich portion can be reacted with an acid comprising phosphorus at conditions sufficient to produce a reacted product comprising glycerophosphoric acid, glycerol, and a portion of the acid.

Abstract: Improved highly stable formulation for aqueous fuel emulsion compositions with a water continuous phase, having reduced NOx emissions. The fuel emulsion formulation includes diesel fuel, purified water, and an additive package that includes one or more surfactants, lubricity additive, cetane improver, anti-corrosion additive, and an alcohol or other suitable antifreeze, the emulsion having an average droplet size of less than 10 microns.

Abstract: The lubricity (anti-wear properties) of hydrocarbon fuels, oxygenate fuels or mixtures thereof, particularly diesel or aviation fuels having reduced sulphur and/or aromatic content for compliance with regulatory requirements, is improved by the addition of a phosphorus ester or esters (phosphates and/or phosphites), or a concentrate containing the ester or esters, having a total acid number at least 1.0 mg KOH/g. The additives also improve corrosion inhibition.

Abstract: A diesel fuel composition which is comprised of:(a) a major portion of a low-sulfur content diesel fuel; and(b) a minor amount, as an anti-wear lubricity additive, of a dithiophosphoric diester-dialcohol.

Abstract: Vinyl pyrrolidinone capped phosphorodithioates have been found to be effective multifunctional antiwear/antioxidant additives for fuel compositions.

Abstract: Compositions comprising a hydrocarbonaceous middle distillate fuel and a minor wear-inhibiting amount of a combination of (i) at least one fuel-soluble aryl phosphate of the formula(RO).sub.3 POwherein each R is, independently, phenyl or an alkyl-substituted phenyl group; and (ii) at least one fuel-soluble aryl polyphosphate of the formula ##STR1## wherein each R is, independently, phenyl or an alkyl-substituted phenyl group, Ar is m-phenylene or an alkyl-substituted m-phenylene group, and n is from 1 to 4. The combination contains from 2 to 30% by weight of component (i). These compositions are made by (a) reacting about 1.9 to about 2.1 equivalents of phenol or alkyl-substituted phenol with one equivalent of phosphoryl trihalide, and (b) reacting the intermediate product formed in (a) with from about 0.9 to about 1.1 equivalents of resorcinol or alkyl-substituted resorcinol per equivalent of phosphoryl trihalide employed in (a). Alternatively, the compositions are made by (a) reacting about 0.9 to about 1.

Abstract: A lubricant or fuel composition contains a multifunctional antioxidant and antiwear amount of an O,O-diorgano-S-(2-hydroxyalkyl) phosphorodithioate derived hydrogen phosphonate which can be made by reacting a diorganophosphorodithioic acid with an epoxide and a dialkyl phosphite, such as dimethyl phosphite.
