Electrolysis of mixtures

Beryllium. Beryllium [7440-41-7], Be, metal is produced by electrolysis of KCl—NaCl—BeCl2 melts. Temperatures up to 900°C are required. CeU voltages are 6 to 9 V (115). Electrolysis of mixtures of beryUium oxide [1304-56-9], BeO, ia lithium fluoride [7789-24-4], LiF, and beryUium fluoride [7787-49-7], BeF2, has produced beryUium metal at about 700°C and 2.6 V (116). DetaUs of fused salt metal winning processes are given ia Table 7. 

Chemiluminescence also occurs during electrolysis of mixtures of DPACI2 99 and rubrene or perylene In the case of rubrene the chemiluminescence matches the fluorescence of the latter at the reduction potential of rubrene radical anion formation ( — 1.4 V) at —1.9 V, the reduction potential of DPA radical anion, a mixed emission is observed consisting of rubrene and DPA fluorescence. Similar results were obtained with the dibromide 100 and DPA and/or rubrene. An energy-transfer mechanism from excited DPA to rubrene could not be detected under the reaction conditions (see also 154>). There seems to be no explanation yet as to why, in mixtures of halides like DPACI2 and aromatic hydrocarbons, electrogenerated chemiluminescence always stems from that hydrocarbon which is most easily reduced. A great number of aryl and alkyl halides is reported to exhibit this type of rather efficient chemiluminescence 155>.

Electrolysis of Mixtures.—Wurtz 3 was the first to conceive the extremely fruitful idea in electrosynthesis of making syntheses of substances with mixed radicals by electrolyzing two components. After discovering his hydrocarbon synthesis, which depends upon the action of sodium upon alkyl iodides, and the use of the method in the preparation of mixed radicals from two different alkyl iodides, he also tried to obtain... 

In the following discussion the description of the electrolysis of mixtures is given under the heading of the highest hydrocarbon component, since the reaction in electrolysis depends upon the nature of the components of the mixtures thus the behavior of each separate component will then have been previously described. 

Yon Miller and Hofer 3 have also carried out the principle of the electrolysis of mixtures, discussed under malonic acid, using potassium ethyl succinate, and submitting the latter to electrolysis at the anode with potassium salts of monocarboxylic acids. They thus obtained on the addition of potassium acetate about 69% of the theoretical quantity of butyric ethyl ester ...

Elemental fluorine is the most powerful oxidizing agent known it may therefore not be prepared by chemical oxidations under ordinary conditions. Commercial quantities of fluorine are prepared today by electrolysis of mixtures of potassium fluoride and hydrogen fluoride (such mixtures containing the F—H—F ion). Electrodes may be of carbon or of a metal (for example, Cu or Ni) that will form a protective fluoride coating. 

Electrolysis of mixtures with nitrogen compounds may form the explosive nitrogen trichloride. Reaction with burning lithium forms the dangerously reactive sodium. The molten salt at 1100° reacts explosively with water. Violent reaction with...
