CONTINUOUS PRODUCTION OF AN ADSORPTION PRODUCT OF A NITROOXY-FUNCTIONAL ORGANIC COMPOUND
The invention relates to a process for the continuous production of an adsorption product of a nitrooxy-functional organic compound adsorbed on the surface of a particulate adsorbent material, the process comprising the steps of: continuously feeding particulate adsorbent material into an elongated cavity; continuously conveying the material within the cavity in a downstream direction; continuously spraying a liquid adsorbate onto the particulate adsorbent material, wherein the liquid adsorbate comprises the nitrooxy-functional organic compound; continuously agitating the mixture thus obtained to form the adsorption product; and continuously removing the adsorption product from the cavity. The invention further relates to an adsorption product obtained by such process and the use of such adsorption product in ruminant nutrition.

Process for the synthesis of 2-nitratoethyl acrylate (2NEA)
An elegant process for the synthesis of 2-nitratoethyl acrylate is a single reactive step. A 2-hydroxyethyl acrylate having only one hydroxyl group is nitrated in a 1:1 volumetric mixture of nitric acid and sulfuric acid therein forming 2-nitratoethyl acrylate. The 2-nitratoethyl acrylate is minimally soluble in a quenched cold acid water mixture, which enables relatively easy isolation of about 96% purity 2-nitratoethyl acrylate at a yield of about 85%.

FUEL ADDITIVES WITH LOW NOx EMISSIONS
This disclosure relates to compositions and methods of making an additized fuel composition comprising a base fuel composition and a randomly branched nitrate composition. The randomly branched nitrate composition includes a plurality of primary nitrate molecules, each molecule therein having an empirical chemical formula of CnNO3, wherein Cn is a branched aliphatic moiety which may be the same or different for each molecule, n is an integer selected from the group consisting of 8, 9, 10, 11 and 12, at least one carbon atom in the branched aliphatic moiety being bound to three or more carbon atoms, a branching index ranging from 1.8 to 2.2, and greater than 80% of the branches in the aliphatic moiety being in other than the alpha position. The additized fuel composition may be diesel fuel composition or a gasoline fuel composition. Such randomly branched nitrate composition may be more stable, and thus safer to handle than 2-ethylhexylnitrate and may have a lower overall nitrogen content, leading to lower NOx emissions upon combustion in diesel and gasoline fuel compositions.
