摘要:
A lubricating oil composition which exhibits improved fuel economy and fuel economy retention which contains keto-amide and keto-ester friction modifiers formed by reaction or trans-esterification of alkyl acetoacetates. The trans-esterified products are also novel compositions of matter.
摘要:
The present invention provides functional fluid compositions containing a major portion of oil of lubricating viscosity and a novel and synergistic combination of an acylated nitrogen-containing compound having an olefinic substituent averaging in carbon number from 20 to 60 and at least one ashless detergent/dispersant.
摘要:
Lubricating oil compositions providing superior soot dispersing characteristics, which contain a combination of a high molecular weight dispersant and a soot dispersant comprising a linked aromatic oligomer
摘要:
Soot induced kinematic viscosity increase of lubricating oil compositions for diesel engines can be ameliorated by combined use of derivatized high molecular weight olefin copolymers and high molecular weight nitrogen-containing dispersant.
摘要:
A dispersant that is a reaction product of a polyalkenyl-substituted mono- or dicarboxylic acid, anhydride or ester; and a polyamine, wherein the reaction product has from greater than about 1.3 to less than about 1.7 mono- or di-carboxylic acid producing moieties per polyalkenyl moiety, and the polyalkenyl moiety has a number average molecular weight of at least about 1800, and a molecular weight distribution (Mw/Mn) of from about 1.5 to about 2.0.
摘要:
A merchandiser system and method for thawing, displaying, and warming previously baked dough products, such as cookies, under controlled drying conditions, including a warming compartment and a merchandiser. The merchandiser controls the drying of moisture in the thawed, baked products to maintain the organoleptic and/or texture properties of the products at essentially the same level as those of freshly baked products for a period of at least about 2 hours.

摘要:
The invention relates to an apparatus for delivering powder in a beverage dispenser comprising a hopper for containing a mass of beverage powder. The hopper includes at least one flexible body member and an actuating mechanism coupled with the flexible body member. The actuating mechanism is operatively associated with a mechanical or magnetic driving device which is actuated in an active mode to actuate the actuating mechanism to impart motion to the flexible body member at a frequency that is sufficiently low to correspond to a non-vibrating mode.
摘要:
The present invention relates to a catalyst composition, its methods of preparation and its use in aromatic alkylation processes. The composition comprises a heteropoly compound selected from the group consisting of heteropoly salts and heteropolyacid salts deposited in the interior of a porous support selected from the group consisting of silica, titania, and zirconia, wherein said salt of said heteropoly salt and said heteropolyacid salt is selected from the group consisting of ammonium, cesium, potassium, and rubidium salts and mixtures thereof, and wherein said heteropoly salt and said heteropolyacid salt are formed with a heteropolyacid selected from the group consisting of 12-tungstophosphoric, 12-tungstosilicic, 12-molybdophosphoric, and 12-molybdosilicic acid.
摘要:
A Koch functionalized product, which is the reaction product of at least one hydrocarbon with carbon monoxide and a nucleophilic trapping agent, is derivatized with a heavy polyamine and a second amine. The hydrocarbon is a hydrocarbon compound or a hydrocarbon polymer. A heavy polyamine is a mixture of polyamines containing small amounts of lower polyamine oligomers such as tetraethylene pentamine and pentaethylenehexamine and containing primarily oligomers with more than 6 nitrogens and more extensive branching. Rubber seals embrittlement is reduced or minimized.
