Description

Изобретение касаетс  электрохимического получени  перборатов щелочных и щелочноземельных металлов, в частности перборага натри .The invention relates to the electrochemical preparation of alkali metal and alkaline earth metal perborates, in particular sodium perborate.

Известен способ получени  пербората натри  в электролизере с платиновыми сетчатыми анодами и катодами из никел , олова или стали , согласно которому электролизуют боратно-карбонатные растворы следующего состава , г/л: ЫагСОз 130-140 NaHCOa 0-30 Na2B4O7-10H2O 16-40 ЫагСггОт 0,1-0,4 MgSiOa или другие A known method of producing sodium perborate in an electrolytic cell with platinum mesh anodes and cathodes of nickel, tin or steel, according to which borate-carbonate solutions of the following composition are electrolyzed, g / l: H2SO3 130-140 NaHCOa 0-30 Na2B4O7-10H2O 16-40 HSAGyOT 0 , 1-0.4 MgSiOa or others

силикаты0,1-2,0.silicates of 0.1-2.0.

Напр жение на электролизере 5,1-6,1 в, выход по току 70%.The voltage on the electrolyzer is 5.1-6.1 V, current output is 70%.

С целью снижени  напр жени  на электролизере и увеличени  выхода пербората натри , предлагаетс  добавл ть в электролит соль азотной кислоты, в частности нитрат натри . Благотворное действие NaNOs сказываетс  при его содержании в электролите от 0,2 до 200 г/л, однако целесообразнее поддерживать концентрацию NaNOs пор дка 100 г/л, что позвол ет, при прочих равных услови х, увеличить выход пербората натри  на 4-5% и снизить напр жение на электролизере на 0,3 в.In order to reduce the voltage on the cell and increase the yield of sodium perborate, it is proposed to add a salt of nitric acid, in particular sodium nitrate, to the electrolyte. The beneficial effect of NaNOs is when its content in the electrolyte is from 0.2 to 200 g / l, however, it is more expedient to maintain the concentration of NaNOs in the order of 100 g / l, which allows, all other conditions being equal, to increase the yield of sodium perborate by 4-5% and reduce the cell voltage by 0.3 volts.

В таблице приведены результаты опытов.The table shows the results of experiments.

Примечание. Услови  опытов: Анод - платинова  сетка из проволоки 0,11 мм, катоды - стальные, охлаждаемые. Da - 0,8 а/см-, температура электролита 10-12°С. Состав раствора (в г/л): ЫагСОз 120, Na2B4O7-ЮНаО 25, NaaCraO 0,2.Note. Experimental conditions: The anode is a platinum wire mesh of 0.11 mm, the cathodes are steel, cooled. Da - 0.8 a / cm-, the electrolyte temperature is 10-12 ° C. The composition of the solution (in g / l): CNOH3 120, Na2B4O7-UNAO 25, NaaCraO 0.2.

Предмет изобретени  3 выми сетчатыми анодами, отличающийс  тем, что, с целью напр жени  на электролизере и увеличени  выхода продукта, 4 в электролит добавл ют соль азотной кислоты , например, нитрат натри , в количестве 0,2-200 г/л, предпочтительно 100 г/л.The object of the invention is 3 mesh anodes, characterized in that, in order to strain the electrolyzer and increase the yield of the product, 4 the nitrate salt, for example sodium nitrate, is added to the electrolyte in an amount of 0.2-200 g / l, preferably 100 g / l.
