The present invention is directed to a process of making alkanolamides wherein the 'aging' time is reduced and the diethanol amide to ester ratio in the finished product is increased. Further provided is an additive composition comprising an alkanolamide which contains a reduced amount of DEA and BHEP.

Process for alaknolamide synthesis

A lubricating oil additive composition comprising the reaction product of a (a) nitrogen-containing reactant, wherein the nitrogen-containing reactant comprises an alkyl alkanolamide, an alkyl alkoxylated alkanolamide, an alkyl alkanolamine, an alkyl alkoxylated alkanolamine or mixtures thereof, and wherein the nitrogen-containing reactant contains less than 10 mass percent of glycerol alkyl ester; (b) a source of boron; and (c) a hydrocarbyl polyol, having at least three hydroxyl groups.

The present invention relates to a process for preparing nonylated diphenylamines which improves nonene usage by recycling and reusing stripped nonene from an earlier process. The process comprising consecutive recycle of recovered nonene is conducted at a sequential two step temperature reaction, namely a more severe temperature followed by a lower temperature. The product prepared by this process is a useful antioxidant for lubricating oil compositions.

Method to prepare nonylated diphenylamine using recycle sequential temperatures

Process for preparing alkylene oxide-adducted hydrocarbyl amides

A fuel composition comprising a major amount of hydrocarbons boiling in the gasoline or diesel range and an alkylene oxide-adducted hydrocarbyl amide reaction product having from about 3 to 50 moles of alkylene oxide per mole of hydrocarbyl amide, wherein the reaction product is prepared by (a) first reacting a fatty acid or fatty acid lower alkyl ester with ammonia or a mono- or di-hydroxy hydrocarbyl amine and (b) subsequently reacting the resulting intermediate with an alkylene oxide to provide a reaction product comprising the alkylene oxide-adducted hydrocarbyl amide, a mixture of mono- and di-ester products, and amine by-products, wherein the amount of amine by-products in the reaction product is less than 7 wt %, based on the total weight of the alkylene oxide-adducted hydrocarbyl amide reaction product, and the amide:ester ratio in the reaction product is in the range of about 0.1:1 to 1.1:1.
