The poor efficiencies of coal-fired power plants in 1896 (2.6 percent on average compared with over forty percent one hundred years later) prompted W. W. Jacques to invent the high temperature (500°C to 600°C [900°F to 1100°F]) fuel cell, and then build a lOO-cell battery to produce electricity from coal combustion. The battery operated intermittently for six months, but with diminishing performance, the carbon dioxide generated and present in the air reacted with and consumed its molten potassium hydroxide electrolyte. In 1910, E. Bauer substituted molten salts (e.g., carbonates, silicates, and borates) and used molten silver as the oxygen electrode. Numerous molten salt batteiy systems have since evolved to handle peak loads in electric power plants, and for electric vehicle propulsion. Of particular note is the sodium and nickel chloride couple in a molten chloroalumi-nate salt electrolyte for electric vehicle propulsion. One special feature is the use of a semi-permeable aluminum oxide ceramic separator to prevent lithium ions from diffusing to the sodium electrode, but still allow the opposing flow of sodium ions. 

The reduction of different aliphatic or aromatic aldehydes or ketones 15 was easily achieved using the combination of dihydrated nickel(II) chloride, lithium and a catalytic amount of naphthalene (16%) or DTBB (8%) in THF, yielding the corresponding alcohols without (534) or with (535) deuterium labelling in 57-86% yield. For imines 536, the same process afforded the corresponding amines 537 or deuterio amines 538 in 54- >95% yield . 

Ni, LiCI Sometimes a chemical symbol (such as those for nickel or lithium chloride here) is written above the y/e/ds symbol. This means that the indicated chemical was added as a catalyst. Catalysts speed up reactions but do not otherwise participate in them.

The third method was based on the reductive cleavage of allyl groups from TV-allyl-V-alkylanilines, employing lithium aluminum hydride and nickel chloride.269 Treatment of 230 with these reagents gave a mixture of products, identified as 231-234.

Treatment of diaryl tellurium dichlorides, obtainable from tellurium tetrachloride and aromatic compounds, with carbon monoxide in the presence of palladium(II) chloride/lithium chloride gives arenecarboxylic acids. Biaryls are formed as by-products1,2. Similar products were obtained when the diaryl tellurium dichlorides were reacted with nickel tetracarbonyl3. 

Doable Chlorides.—Nickel chlorides unite with the chlorides of many other metals, particularly the alkali metals and ammonium, to form double salts. Chief amongst these are nickel ammonium chloride, NH4C1. NiCIa. 6H20, which occurs as green, monoclinic crystals. Nickel lithium ckloride,10 LiCl. NiCl2.6H20, yields deliquescent, golden prisms.

Another form of active nickel catalyst has been prepared by the reaction of lithium iso-propoxide with nickel chloride to give nickel iso-propoxide. Heating this salt to 100°C in iso-propanol gives a black, finely divided nickel catalyst that is active for the hydrogenation of a variety of functional groups. ...

NICKEL CHLORIDE (7718-54-9) NiClj Violent reaction with chlorine nitrate. Mixtures with potassium produces an impact-sensitive explosive. Contact with strong acids or acid fumes produces highly toxic and corrosive HCl gas. Forms heat- or shock-sensitive explosives with ammonium nitrate. Increases sensitivity to heat, impact, or friction of hydrazinium perchlorate. Incompatible with gold, lithium, sodium, sulfur. Thermal decomposition emits toxic chloride fumes.

Attempts to convert the sulfones back into PASHs have been successful with a number of agents such as various metals (zinc, tin, magnesium, aluminum, iron, and nickel) in acetic acid, palladium on carbon with hydrazine, stannous chloride, lithium triethylborohydride, diphenylsi-lane, sodium borohydride, boron trifluoride, dicyclohexylcarbodiimide, triethyl phosphite, dimethyl dichlorosUane with lithium aluminum hydride, diphenylsilane, and triphenyl phosphine with iodine. However, none of them cleanly effect this conversion.
