Abstract
1. Способ получения метилата ниобия путем анодного растворения металлического ниобия в метаноле, содержащем фоновый электролит, в электролизере без разделения электродных пространств, отличающийся тем, что процесс электролиза ведут в электролизере с горизонтальным расположением электродов, причем катод располагают выше анода, по завершении процесса католит и анолит смешивают, электропроводящую добавку и метилат ниобия выделяют из раствора известными методами. ! 2. Способ по п.1, отличающийся тем, что электролиз ведут без перемешивания, чем обеспечивается накопление тяжелого анодного слоя, содержащего соединения ниобия. ! 3. Способ по п.1, отличающийся тем, что в качестве фонового электролита используют хлориды щелочных металлов в концентрации 0,05-2,0 моль/л, предпочтительно хлорид лития. ! 4. Способ по п.1, отличающийся тем, что электролиз ведут при плотности тока не выше 0,1 А/см2 и температуре 20-30°С. ! 5. Способ по п.1, отличающийся тем, что синтез ведут до достижения концентрации алкоксида в растворе в пределах 1,3 М.1. A method for producing niobium methoxide by anodic dissolution of niobium metal in methanol containing a background electrolyte in an electrolytic cell without separation of the electrode spaces, characterized in that the electrolysis process is carried out in an electrolytic cell with a horizontal arrangement of electrodes, and the cathode is placed above the anode, upon completion of the process, the catholyte and the anolyte is mixed, the electrically conductive additive and niobium methoxide are separated from the solution by known methods. ! 2. The method according to claim 1, characterized in that the electrolysis is carried out without stirring, which ensures the accumulation of a heavy anode layer containing niobium compounds. ! 3. The method according to claim 1, characterized in that alkali metal chlorides are used as a background electrolyte at a concentration of 0.05-2.0 mol/l, preferably lithium chloride. ! 4. The method according to claim 1, characterized in that the electrolysis is carried out at a current density not higher than 0.1 A/cm2 and a temperature of 20-30°C. ! 5. The method according to claim 1, characterized in that the synthesis is carried out until the alkoxide concentration in the solution reaches 1.3 M.
