摘要:A method for the anodic electrochemical synthesis of ammonia gas. The method comprises providing an electrolyte between an anode and a cathode, providing nitrogen and hydrogen gases to the cathode, oxidizing negatively charged nitrogen-containing species and negatively charged hydrogen-containing species present in the electrolyte at the anode to form adsorbed nitrogen species and adsorbed hydrogen species, respectively, and reacting the adsorbed nitrogen species with the adsorbed hydrogen species to form ammonia. Nitrogen and hydrogen gases may be provided through a porous cathode substrate. The negatively charged nitrogen-containing species in the electrolyte may be produced by reducing nitrogen gas at the cathode and/or by supplying a nitrogen-containing salt, such as lithium nitride, into the molten salt electrolyte. Similarly, the negatively charged hydrogen-containing species in the electrolyte may be produced by reducing hydrogen gas at the cathode and/or by supplying a hydrogen-containing salt, such as lithium hydride, into the molten salt electrolyte.

摘要:The compounds of general formula II are new and represent important intermediates in the synthesis of tapentadol. In the synthesis of tapentadol of formula I and its pharmaceutically acceptable salts, O-protected (2R,3R)-acids of general formula II, in step A, are reacted in an inert organic solvent with an activating agent, optionally in presence of a catalyst or a base; in step B, the obtained compounds of general formula V, wherein R has the above mentioned meaning and X stands for chlorine or alkoxycarbonyloxyl group O-CO-OR 1 or pivaloyloxyl O-CO-t-Bu group, wherein R 1 is methyl or ethyl, are reacted with dimethylamine or its salts optionally in presence of a base; in step C, the obtained N, N-dimethylamides of general formula VI, wherein R has the above mentioned meaning, are reduced by means of hydride agents in a suitable solvent; in step D, the produced alkeneamines of general formula VII, wherein R has the above mentioned meaning, are hydrogenated on a metal catalysts in a suitable solvent; and, finally, in step E, the produced alkaneamines of general formula VIII, wherein R has the above mentioned meaning, are O-dealkylated by means of dealkylating agents, and, if required, the obtained tapentadol is converted by the action of a pharmaceutically acceptable acid to respective salts, e.g. hydrochloride.

摘要:A method of producing submicrometer- to micrometer-sized spherical particles, the method comprising dissolving a lithium salt and a metal salt in water or alcohol forming a precursor solution, spraying the precursor solution to form fine aerosolized droplets, flowing the aerosolized droplets into a pyro lysis flame producing submicrometer- to micrometer-sized spherical particles. The submicrometer- to micrometer-sized spherical lithium-metal oxide powders produced are cathode materials for Li-ion batteries.
