| 044330000 | Compound of indeterminate structure prepared by reacting a heterocyclic compound of known structure | 6 |
| 20130133243 | QUATERNIZED NITROGEN COMPOUNDS AND USE THEREOF AS ADDITIVES IN FUELS AND LUBRICANTS - The present invention relates to novel quaternized nitrogen compounds, to the preparation thereof and to the use thereof as a fuel and lubricant additive, more particularly as a detergent additive; to additive packages which comprise these compounds; and to fuels and lubricants thus additized. The present invention further relates to the use of these quaternized nitrogen compounds as a fuel additive for reducing or preventing deposits in the injection systems of direct-injection diesel engines, especially in common-rail injection systems, for reducing the fuel consumption of direct-injection diesel engines, especially of diesel engines with common-rail injection systems, and for minimizing power loss in direct-injection diesel engines, especially in diesel engines with common-rail injection systems. | 05-30-2013 |
| 20130305594 | METHOD FOR PRODUCING LIQUID HYDROCARBON FUELS DIRECTLY FROM LIGNOCELLULOSIC BIOMASS - A process that directly converts carbohydrates, particularly biomass derived carbohydrates and more specifically biomass (e.g., lignocellulosic biomass), to furfural-/HMF-ketone adducts for liquid hydrocarbon production under mild conditions. | 11-21-2013 |
| 044331000 | The heterocyclic compound reactant is a dicarboxylic acid anhydride (e.g., reaction product of succinic anhydride with a polyamine, etc.) | 2 |
| 20140123546 | DIESEL FUEL ADDITIVE - A diesel fuel additive composition, a fuel containing the fuel additive, a method for improving diesel engine performance using the additive. The diesel fuel additive includes a reaction product of (a) a hydrocarbyl-substituted acylating agent and (b) a reactant selected from the group consisting of a nitrogen-containing compound, a hydroxyl-containing compound, and water that provides a reaction product selected from the group consisting (1) a mono-amide/mono-acid or metal free mono-acid salt thereof, (2) a diacid or metal free diacid salt thereof, and (3) mono-ester/mono-acid or metal free mono-acid salt thereof. The reaction product includes at least about 10 molar percent acid groups based on total moles of the reaction product. | 05-08-2014 |
| 20150361373 | PROCESS FOR CLARIFYING BIOFUELS - Haze may be removed from a biofuel or biofuel intermediate by using a clarifier. The clarifier includes copolymer prepared using a formulation comprising an alpha olefin and maleic anhydride. The clarifier may also be used with admixtures of biofuels, biofuel intermediates, or biofuel feedstocks with conventional hydrocarbons. | 12-17-2015 |
| 044332000 | The heterocyclic compound reactant is an oxirane (e.g., reaction product of epihalohydrin with amine, epoxide reactions, etc.) | 2 |
| 20120192483 | Quaternary Ammonium Salt Detergents For Use In Fuels - A quaternary ammonium salt detergent made from the reaction product of the reaction of: (a) a hydrocarbyl substituted acylating agent and a compound having an oxygen or nitrogen atom capable of condensing with said acylating agent and further having a tertiary amino group; and (b) a quaternizing agent suitable for converting the tertiary amino group to a quaternary nitrogen and the use of such quaternary ammonium salt detergents in a fuel composition to reduce intake valve deposits. | 08-02-2012 |
| 20140318002 | ADDITIVE FORMULATION SUITABLE FOR ANTISTATIC MODIFICATION AND IMPROVING THE ELECTRICAL CONDUCTIVITY OF INANIMATE ORGANIC MATERIAL - An additive formulation suitable for antistatic modification and improving the electrical conductivity of inanimate organic material, consisting essentially of
