Nitrate de lithium

Conversion of ketone 80 to the enol silane followed by addition of lithium aluminum hydride to the reaction mixture directly provides the allylic alcohol 81 [70]. Treatment of crude allylic alcohol 81 with tert-butyldimethylsilyl chloride followed by N-b ro m o s u cc i n i m i de furnishes the a-bromoketone 82 in 84 % yield over the two-step sequence from a.p-unsaturated ester 80. Finally, a one-pot Komblum oxidation [71] of a-bromoketone 82 is achieved by way of the nitrate ester to deliver the glyoxal 71. It is worth noting that the sequence to glyoxal 71 requires only a single chromatographic purification at the second to last step (Scheme 5.10).

ACETATO de ETILO (Spanish) (141-78-6) Forms explosive mixture with air (flash point 135°F/57°C oc). Violent reaction with oxidizers, chlorosulfonic acid. Incompatible with strong acids, nitrates, lithium aluminum hydride, lithium tetrahydroaluminate, oleum. Will hydrolyze on standing, forming acetic acid and ethyl alcohol this reaction is greatly accelerated by strong bases. 

CLORURO de NIQUEL (7718-54-9) Violent reaction with chlorine nitrate, potassium. Mixing with potassium produces an impact-sensitive explosive. Forms heat- or shock-sensitive explosives with ammonium nitrate. Increases sensitivity to heat, impact, or friction of hy-drazinium perchlorate. Incompatible with chloric acid, gold, lithium, sodium acetylide. 

OXIDO de CADMIO (Spanish) (1306-19-0) Forms explosive mixture with aluminum, ammonium perchlorate, magnesium in the presence of heat, chlorine trifluoride. Explodes or ignites on contact with hydrazinium nitrate, hydrogen peroxide (90%), hydrogen sulfide, hydrogen trisulfide, lithium. Can increase the thermal and explosive sensitivity of nitroalkanes, hydrazinium perchlorate. May react with phosphorus, sulfur, sulfur dioxide, sulfur trioxide, selenium, zinc. 

SQM, as Eoote, initially selected a brine extraction location for its well field where the brine had the maximum potassium and the least sulfate for potash and lithium production, and later a location with the maximum sulfate content for potassium sulfate production (Fig. 1.57). Because of this the plants could initially use the simplest processes and have the lowest capital and operating costs. In the initial operation brine with up to 3400 ppm Li was pumped from the Salar in 40 wells, 28 m deep on a 200-500 m grid, which delivered up to 5280 m /hr of brine to the solar ponds. There were also 13 monitoring wells to follow any changes in the brine concentration and its depth from the surface. The ponds were lined with flexible PVC or reinforced hypalon membranes, and the brine flowed through the sections of the pond system in series. The initial salt ponds had an area of 1.16 million m followed by 3.36 million m for the sylvinite ponds, and later 1 million m of ponds were installed for lithium production. The plant employed 184 people, of which 120 were hired from the sparsely populated local area. Contractors were used to drill and maintain the weUs, harvest the salts, transport them to their respective stockpiles, and reclaim the sylvinite to feed the potash plant s conveyor belt. They also provided all of the miscellaneous trucking needed at the Salar, and transported the potash to Coya Sur or Maria Elena and the concentrated lithium chloride brine to the Salar de Carmen. SQM unloaded the brine and potash, and stacked the later material at its nitrate plants (Harben and Edwards, 1997).
