摘要:A method for the electrochemical synthesis of ammonia (NH 3 ) comprises contacting a nitrogen-containing gas with the cathode of an electrochemical cell comprising a cathode, an anode, an alkaline aqueous electrolyte, and preferably an anion exchange membrane. The cathode is a porous gas diffusion electrode which comprises an active layer comprising a material which is capable of catalyzing the electrochemical reduction of nitrogen and is in contact with the electrolyte, a layer of electroconductive material supporting the active layer, and a porous polymer film on the side of the active layer which does not come into contact with the electrolyte and comes into direct contact with the nitrogen-containing gas. A potential over the electrochemical cell is applied to effect the electrochemical synthesis of ammonia from nitrogen and water. The method can be used to synthesize ammonia without using molecular hydrogen.

摘要:A multi-step method for the continuous synthesis of ibuprofen or a synthetic precursor of ibuprofen is provided that does not require any intermediate purification or isolation steps and uses reagents compatible with downstream reactions. According to some embodiments, a method is provided wherein isobutylbenzene and a propionyl compound may be converted into a first product in a first Friedel Crafts acylation reaction. The first product may then be converted into a second product in a 1,2-aryl migration reaction. Finally, the second product may be converted into ibuprofen in a hydrolysis reaction. The present invention also provides a method wherein only the first and second reaction steps or only the second and third reaction steps are performed. An apparatus is also provided having two or more microreactors and two or more junctions in particular arrangements for the synthesis of ibuprofen or a synthetic precursor of ibuprofen.
