Abstract: The invention “Method for selective synthesis of N-methyl-para-anisidine” relates to chemical technology processes, namely to catalytic alkylation of aromatic amines and nitro compounds. The invention relates to the method for synthesis of N-methyl-para-anisidine (N-methyl-para-methoxyaniline; N-methyl-para-amino anisole) from para-anisidine (para-amino anisole; para-methoxyaniline) or para-nitro anisole (1-methoxy-4-nitrobenzene) and methanol in the presence of hydrogen or without hydrogen on heterogeneous catalyst. Proposed method permits to use existing process plants used for obtaining aniline and 14-methylaniline. The invention purpose is to provide the possibility to produce N-methyl-para-anisidine with purity at least 98% and high output that allows arrangement of highly profitable industry-scale manufacturing process.

Abstract: The invention relates to application of N-monomethyl-4-methoxyaniline, N-monomethyl-4-ethoxyaniline and N-monomethyl aniline and their mixtures as oxidation-preventive additives for engine fuel. This invention may be used to improve their performance parameters. It also relates to fuel compositions containing the above-mentioned chemical compounds.

Abstract: An energy system may use an alternative, universal, promising, carbon-free, flameless fuel, based on an aqueous solution of ammonium nitrate and/or nitrite or mixtures thereof, wherein the ammonium nitrate and/or nitrite are used in amounts providing, upon their decomposition, a release of energy for forming high pressure vapor-gas mixture to perform work. Upon introduction of organic substances to the fuel composition, stable, homogeneous solutions may be formed also useful as fuel. An engine may perform work by initiating a reaction in on the fuel to expand a gas or fluid within an internal combustion engine or the like.
