摘要： A process for producing amino alcohols by electrosynthesis of nitro alcohols.Reduction of the nitro group is performed in three stages on a cathode made of a material having a strong hydrogen overpotential. During the second stage of reduction, the electronegative potential is higher, and in the last stage the sulfuric solution of amino alcohol obtained is subjected to a purification operation by electro-electrodialysis (EED), followed by an elimination of water.The process is particularly useful for the production of 2-nitro-2-methyl-1-propanol, 2-nitro-2-methyl-1, 3-propanediol, 2-nitro-2-ethyl-1, 3-propanediol, 2-nitro-1-butanol, tris(hydroxymethyl) nitromethane.

摘要： A process for preparing peroxydisulfates by electrolysis in a diaphragm cell uses a diaphragm, the active part of which comprises a cation exchange polymer made up of a membrane with a sulfonated polystyrene base resin supported by a polypropylene fabric. The process is applicable to the preparation of peroxydisulfates of alkali metals and of ammonium.

摘要： A fluid purification and recovery system includes a buffer section configured to receive a fluid delivered from a process station, where the fluid pressure is maintained within the buffer section within a predetermined range and the fluid is maintained within the buffer section in at least one of a gas state, a liquid state and a supercritical state. The system further includes a purification section disposed downstream from the buffer section to receive the fluid from the buffer section, where the purification section includes at least one purification unit that separates at least a portion of at least one component from the fluid. In one embodiment, the fluid is maintained in at least one of a liquid state and a supercritical state in both the buffer section and the purification section. In addition, the buffer section delivers the fluid to the purification with minimal or substantially no fluctuations in pressure.
