    Abstract: A 4-alkyl-2-morpholinone is prepared by reacting glyoxal with a C.sub.1 -C.sub.18 N-alkylmonoethanolamine in solution in a solvent that azeotropes with water at a temperature of about -10.degree. to 20.degree. C. for about 1 to 5 hours and by then heating the reaction mixture to a temperature of at least about 110.degree. C. to remove an azeotrope of water and solvent from the mixture to thereby substantially selectively convert the C.sub.1 -C.sub.18 N-alkylmonoethanolamine to the corresponding 4-alkyl-2-morpholinone.

    Abstract: A method is disclosed for the improved production of N-methylpyrrolidine at moderate conditions which comprises the steps of reacting N-methylpyrrolidone with hydrogen over a copper chromite catalyst at a moderate temperature and a pressure of 1000 psig to 5000 psig and thereafter isolating the N-methylpyrrolidine by extraction with an aliphatic hydrocarbon solvent having a boiling point less than 70.degree. C. or greater than 90.degree. C.

    Abstract: Inclusion of a branched alcohol in the catalytic hydrogenation reaction involving an aliphatic nitro compound dramatically increases the efficiency of the conversion of nitro groups into amino groups. This discovery is of particular value in the production of polyalkyleneamines via nitration of a polyalkene, such as a polybutene, and its subsequent reduction. The polyalkyleneamines so produced are useful as dispersant additives for motor oils and fuels.

    Abstract: Polyalkyl hydroxyaromatics may be prepared from polyalkylenes and hydroxyaromatics in the presence of an acid catalyst and an organic solvent having a boiling point range with an initial boiling point value of below or about the boiling point of the selected hydroxyaromatic reactants and final boiling point of above or equal to about the boiling point of alkylhydroxyaromatic by-product of the reaction. Using this method, accumulation of undesirable alkylhydroxyaromatic by-product/s in a reaction vessel may be minimized, and/or viscosity of polyalkyl hydroxyaromatic product reduced, allowing for increased ease of transfer and transportation.

    Abstract: A process for the alkoxylation of a polyetheramine to form an etheramine alkoxylate. In the process, a polyetheramine is reacted with an alkylene oxide in the presence of an alcohol to form the etheramine alkoxylate. The alcohol serves as a catalyst to allow the reaction proceed at a heightened temperature as compared to the reaction in the absence of alcohol, while at the same time limiting the amount of glycol by-product production which would otherwise typically form when higher polyetheramines are to be alkoxylated. The alcohol may be, for instance, ethanol or methanol.
