Method of manufacture of alcohols, amino - by reduction subject-matter of the nitro - alcohol

摘要

The invention relates to a method of manufacturing amino - alcohols for electrosynthesis of nitro alcohols -. & br / in the process in three steps, it is the reduction of the nitro group on a cathode made of a material having a strong hydrogen overpotential, during the second reduction stage, the voltage electronegative is higher, and in the last step is subjected, the sulfuric solution of amino - alcohol obtained in a step of purification by electro - electrodialysis eed and then to eliminate the water. & br / application of the process in particular to the nitro - 2 methyl - 2 propanol - 1, nitro - 2 - methyl - 2 - propanediol - 1,3, nitro - 2 - ethyl - 2 propanediol 1 - 3, nitro - 2 butanol - 1, tris (hydroxymethyl) nitro -.
