Recovery Process. Lithium is extracted from brine at Silver Peak Marsh, Nevada, and at the Salar de Atacama, Chile. Both processes were developed by Foote Mineral Corp. The process at Silver Peak consists of pumping shallow underground wells to solar ponds where brines are concentrated to over 5000 ppm. Lithium ion is then removed by precipitation with soda ash to form a high purity lithium carbonate [554-13-2]. At the Atacama, virgin brine with nearly 3000 ppm lithium is concentrated to near saturation in lithium chloride [7447-41 -8]. This brine is then shipped to Antofagasta, Chile where it is combined with soda ash to form lithium carbonate. [Pg.411]

Pulverized ferrosilicon containing approximately 15 percent sihcon is available from the Foote Mineral Company and from Carborundum Co. in the sizes and at the prices shown in Table 19-14. Cost is based on truckload quantities in 227-kg (500-lb) steel drums, FOB Keokuk, Iowa, and Niagara Falls, Ontario. [Pg.1790]

The reaction of lithium with methyl chloride in ether solution produces a solution of methyllithium from which most of the relatively insoluble lithium chloride precipitates. Ethereal solutions of halide-free" methyllithium, containing 2-5 mole percent of lithium chloride, were formerly marketed by Foote Mineral Company and by Lithium Corporation of America, Inc., but this product has been discontinued by both companies. Comparable solutions are also marketed by Alfa Products and by Aldrich Chemical Company these solutions have a limited shelf-life and older solutions have often deteriorated... [Pg.107]

We are indebted to Dr. W. Novis Smith, formerly with Foote Mineral Company, and now with Stauffer Chemical Company, Dobbs Ferry, New York, for supplying the general preparative procedure which we have adapted to the laboratory-scale preparation described here. [Pg.108]

Both sodium acetylide in xylene (Air Reduction Corporation) and lithium acetylide-ethylenediamine complex (Foote Mineral Co.) are now commercially available, and have been used successfully for the ethynylation of 17-keto steroids. [Pg.136]

The reaction is carried out under argon in a 2-liter three-necked flask fitted with a mechanical stirrer, reflux condenser, 250-ml pressure-equalizing addition funnel, and gas inlet and outlet. After purging with argon, the flask is charged with a solution of 89 g (0.48 mole) of ferrocene in 1 liter of dry tetrahydrofuran. The solution is next heated to 45°, and there is added dropwise with stirring, 155 ml (0.29 mole) of an -butyllithium solution (15% in heptane-pentane, 2 1, Foote Mineral Co.) during a period of 75 minutes. The resultant solution is maintained at 45° for an additional 2 hours, then is cooled to —77° by means of an external Dry Ice-chloroform bath. [Pg.65]

The reaction is carried out in a manner similar to that described above (Chapter 11, Section II). In a 250-ml flask fitted with stirrer, condenser, and dropping funnel is placed a solution of 19.25 g (0.0505 mole) of the phosphonium salt in 180 ml of THF. The nitrogen atmosphere is established and 0.05 mole of phenyllithium added (as a solution in benzene, available from Foote Mineral Co.). The mixture is stirred for 45 minutes at room temperature and then refluxed for 15 minutes. To the red-brown solution is added dropwise over 20 minutes 4.91 g (0.05 mole) of distilled cyclohexanone stirring is continued for 24 hours. The mixture is then concentrated by distillation at... [Pg.109]

Commercial solutions of butyllithium were obtained from Foote Mineral Company. [Pg.2]

Commercial butyllithium (Foote Mineral Company, ca. 15% in hexane) and six equivalents of lithium were used. [Pg.11]

The concentration of the butyllithium obtained from Foote Mineral Company is generally close to the 1.6M as quoted. An exact measurement of the volume (hypodermic syringe recommended) is not necessary, but a slight excess above the stoichiometrically required amount (0.20 mole) is needed. The submitters used butyllithium available from Lithium Corporation of America, Inc. [Pg.41]

Solutions containing approximately 1.6JH butyllithium in hexane were purchased either from Alfa Inorganics, Inc., or from Foote Mineral Company, The concentration of butyllithium in these solutions can be determined either by a double titration procedure2 or by dilution with anhydrous tetrahydro furan followed by titration with 2-butanol in the presence of a 2,2 -bipyridyl indicator.3 In either ease the total base concentration in the reagent is determined by titration with standard aqueous acid. [Pg.124]

The n-butyllithium in hexane was purchased from Foote Mineral Company, Exton, Pa. The diethylamine was dried over sodium hydroxide, and the solvents were dried over sodium metal. [Pg.137]

Butyllithium was obtained as a solution in hexane from Foote Mineral Ltd. and titrated with 0.5 M 2-propanol in tetrahydrofuran (THF) with 1,10-phenanthroline as the indicator. The butyllithium was transferred via Teflon cannula under positive nitrogen pressure. The checkers used a 1.6 M solution of butyllithium purchased from Aldrich Chemical Company, Inc. [Pg.112]

The submitter used a 1.24M solution of n-butyllithium in pentane obtained from Foot Mineral Co., and the checkers used a 1.45M solution of w-butyllithium in hexane obtained from Wako Pure Chemical Industries Ltd. (Japan). The nominal titer of active alkyl on the bottle agreed well with the value found by titration2 with 0.S0M (submitter) or 0.50JJ (checkers) solution of 2-butanol in xylene using 1,10-phenan-throline as indicator. [Pg.12]

The submitters used an ether solution of halide-free methyl-lithium, purchased from Foote Mineral Company, and the checkers prepared the compound from methyl chloride and lithium metal in ether according to the literature.2 The solution was standardized before use by the titration procedure described in a previous volume of this series.3 The checkers observed that use of a halide-containing ether solution of methyllithium resulted in a considerable decrease in yield of the product, principally due to difficulty in following the subsequent procedure described in the text. [Pg.97]

Methyllithium (prepared from methyl chloride), available from Foote Mineral Company, can be used without further purification. Attention should be drawn to the following methyllithium purchased from Alfa Inorganics is prepared from methyl bromide and thus produces a mixture of geranyl bromide and chloride. [Pg.105]

An ethereal solution which was 1.38ilf in methyllithium was purchased from Foote Mineral Company. The concentration of methyllithium in ethereal solutions may be conveniently determined by a procedure described elsewhere in which the lithium reagent is titrated with 5ec-butyl alcohol, utilizing the charge transfer complex formed from bipyridyl or o-phenanthro-line and the lithium reagent as an indicator. [Pg.124]

Ethereal solutions of methyllithium are available from either Foote Mineral Company or Alpha Inorganics, Inc. These solutions should be titrated immediately before use with 2-butanol and 2,2-bipyridyl as an indicator. In a typical run, 2.44 ml. of ethereal 1.64iH methyllithium was employed. [Pg.57]

Methyllithium available from either Foote Mineral Company or Alfa Inorganics, Inc. can be used without further purification. The checkers used 137 ml. of a 1.85ilf solution. [Pg.35]

The checkers used 120 ml. of 1.6M n-butyllithium in hexane, obtained from Foote Mineral Company. [Pg.105]

The titer of the solution should be determined prior to use. The checkers used product available from Foote Mineral Company. [Pg.124]

Available from Foote Mineral and Chemicals, Route 100, Exton, PA 19341. t Available from Matheson Gas Products, P.O. Box 85, 932 Paterson Plank Rd., E. Rutherford, NJ 07073. [Pg.179]

To a stirred reaction mixture consisting of 55.0 gm (0.50 mole) of c/s-cyclo-octene and 41.5 gm (0.125 mole) of carbon tetrabromide cooled to —65°C is added 74.0 ml (0.125 mole) of methyllithium in ether (Foote Mineral Co.) over a 45 min period. After stirring at -65° to -68°C for an additional hr, another 80.5 ml (0.135 mole) of methyllithium is added over a -hour period. The reaction mixture is stirred for another i hr at —68°C, warmed to 0°C, water added, the ether separated, washed with water until neutral, dried over sodium sulfate, and then fractionally distilled to afford 11.3 gm (74%), b.p. 62°-63°C (16 mm), d° 1.5060. [Pg.265]

Butyllithium in hexane was obtained from Foote Mineral Company. The solution can be titrated for total alkyllithium by the procedure of Watson and Eastham,s and for total base by hydrolysis of aliquots and titration against standard acid prior to use. Butyllithium solution of good purity is essential for success of the reaction. [Pg.27]

Butyllithium was obtained from Foote Mineral Co., Johnsonvllle, Tennessee. It may be standardized by a double titration procedure. ... [Pg.110]
