Description

Перманганат кали  получаетс  путем окислени , обычно электролитическим путем, манганата кали , получаемого, в свою очередь,сплавлением перекиси марганца (MnOg) с едким калием.Potassium permanganate is obtained by oxidation, usually electrolytically, of potassium manganate, which is produced, in turn, by fusing manganese peroxide (MnOg) with potassium hydroxide.

Электролитическое окисление в насто щее врем  вытеснило все другие методы (хлорирование, карбонизаци ) получени  перманганата; процессы, протекающие при электролизе, можно выразить следующим уравнением:Electrolytic oxidation has now superseded all other methods (chlorination, carbonization) of producing permanganate; the processes occurring during electrolysis can be expressed by the following equation:

2К2МпО4 + 2Н + 2ОН 2КМпО4 + КОН + Н22K2MnO4 + 2H + 2ON 2KMnO4 + KOH + H2

Реакци  эта обратима ,°а потому не удаетс  проводить окисление манганата в перманганат с выходом по току, близким к 100%. В примен емых в насто щее врем  в технике электролитических ваннах бездиафрагмейного типа выход по току бывает не более 75/0.This reaction is reversible, and therefore it is not possible to carry out the oxidation of manganate to permanganate with a current efficiency close to 100%. In the electrolytic baths of diaphragmatic type used at present in the technique, the current output is no more than 75/0.

При применении в электролитических ваннах диафрагмы достигались выхода по току около 70--85%. Автором установлено, что вполне возможно получать перманганат кали  с выходами по току в 90-95%, если вести процесс в ванне с двум  диафрагмами. Ванна, изображенна  схематически на фиг. 1 и 2, представл ет собой железный цилиндр А, в котором помещен сетчатый никелированный анод Б, окруженный диафрагмой В из асбестового картона или льн ной ткани. Далее установлены втора  диафрагма асбеста же или льн ной ткани и железный катод Д.When used in electrolytic baths, the diaphragm achieved a current efficiency of about 70--85%. The author found that it is quite possible to get potassium permanganate with current outputs of 90-95%, if the process is conducted in a bath with two diaphragms. The bath shown schematically in FIG. 1 and 2 is an iron cylinder A, in which a nickel-plated mesh anode B is placed, surrounded by a diaphragm B made of asbestos cardboard or linen fabric. Next, a second asbestos diaphragm of the same or linen fabric and an iron cathode D are installed.

Раствор манганата поступает в междиафрагмовое пространство и фильтруетс  через диафрагмы в анодное и катодное пространства.The manganate solution enters the inter-aperture space and is filtered through the diaphragms into the anode and cathode spaces.

Благодар  наличию двух диафрагм и не заполненным электродным пространствам продукты электролиза не смешиваютс  друг с другом; поэтому вышеуказанна  реакци  (2К2МпО4 -|-f 2НзО : 2КМпО -f 2КОН + Н,) осуществл етс  наиболее полно слева направо . Процесс электролиза требует напр жени  на электродах 2,5-3 вольта и плотности тока на катоде 750 Р(/м- и на аноде 350 Д/Ои-.Due to the presence of two diaphragms and unfilled electrode spaces, the electrolysis products do not mix with each other; therefore, the above reaction (2K2MnO4 - | -f 2H3O: 2KMnO -f 2KOH + H,) is performed most completely from left to right. The process of electrolysis requires a voltage on the electrodes of 2.5-3 volts and a current density at the cathode of 750 R (/ m and anode at 350 D / Oi.

Предмет изобретени .The subject matter of the invention.

Способ электролитического получени  перманганата кали  путем электролиза раствора манганата кали , отличающийс  тем, что электролиз ведут в ванне с двум  диафрагмами и электролит подают в междиафрагмовое пространство.A method of electrolytically producing potassium permanganate by electrolysis of a solution of potassium manganate, characterized in that the electrolysis is carried out in a bath with two diaphragms and the electrolyte is fed into the interphrenic space.
