Abstract: Disclosed are a process and an apparatus for synthesizing nitroalkanes by reaction of a hydrocarbon feedstock with aqueous nitric acid. By using an isothermal reactor with multiple input ports for aqueous nitric acid, a hydrocarbon feedstock may be sequentially exposed to a plurality of flows of aqueous nitric acid as it flows through the reactor.
Abstract: A method for marking a petroleum hydrocarbon, biodiesel fuel or ethanol fuel by adding to the petroleum hydrocarbon, biodiesel fuel or ethanol fuel at least one compound having formula (I) wherein R1 and R2 independently represent at least one substituent selected from the group consisting of hydrogen, C1-C12 alkyl, C1-C12 alkoxy and nitro; and R3 and R4 independently represent hydrogen, methyl or ethyl.
Abstract: Provided is a process for making a tertiary aminoalcohol compound. The process comprises using an excess amount of a carbonyl compound in a condensation step between the carbonyl compound and a nitroalkane, and conducting a hydrogenation/alkylation step to produce the tertiary aminoalcohol. The process uses fewer steps than conventional processes.

Abstract: An additive for an aqueous metalworking fluid (MWF) comprises a C12-20 fatty acid neutralized with at least one of an amine, alkanolamine and a caustic. The additive is designed for use in an aqueous MWF having a pH of at least about 7 and comprising at least about 0.10 weight percent, based on the weight of the MWF, of the neutralized C12-20 fatty acid. The additive inhibits the staining of ferrous and nonferrous metals during and after machining.
