YieldReaction ConditionsOperation in experiment
100% Solid Al2(SO4)3.18H2O 1000 g (3.0 mol of Al) was gradually added into stirred D.I. water (2.0 L), followed by solid Na2SO4 213.0 g (3.0 mol of Na). The mixture was stirred to complete dissolution (about 30 min), the total solution volume was adjusted to 2.7 L volume by addition of D.I. water. The resulting 1.1 M solution was filtered before use through a fine 0.45 micron SteriCup Durapore membrane, to obtain 2.7 L of 1.1M solution of NaAl(SO4)2. This 1.1M NaAl(SO4)2 solution was combined with 226.9 g of the Cs salt (0.350 mol) from Example 5, in a 4 L beaker. Solid powdered CsCl 6.0 g was added to the mix, to seed the formation of Cs alum. The mixture was stirred magnetically with a large Teflon-coated rod stirbar for 30 hours at ambient temperature. During this time, the red-brown slurry of the cesium salt turned into coffee-brown black slurry of IT-139 intermixed with fine white salt-like crystals of cesium aluminum salts. The solids were collected by filtration, using a medium porosity Buchner (3 L), the reaction flask and the solids were thoroughly washed with saturated (=1.5M) aqueous Na2SO4, about 1.5 L total (in three portions, 3×0.5 L, until the filtrates were colorless), and the solids were dried by suction on Buchner funnel, followed by drying in vacuo for at least 1 day. The thoroughly dried solids were transferred into a 2 L wide mouth Erlenmeyer flask with 700 mL acetonitrile. The mixture was stirred mechanically for 15 min. The resulting orange slurry was filtered, the insoluble sulfate salts were removed from the mixture on a medium porosity Buchner funnel. The salt cake was rinsed with additional acetonitrile 300 mL (3×100 mL, until colorless) and then discarded. The combined orange filtrates in a 5 L round flask were diluted with 4 L of MTBE (added in four 1 L portions, with gentle stirring), the flask was set aside for 30 min to complete the precipitation. The precipitated crude Na salt was collected by filtration, rinsed thoroughly with MTBE (2×0.5 L) and then dried by suction and in vacuo. The yield was 190.4 g (100% of theory, calculated as the dihydrate) of a crude product as fluffy brown solid, retaining MTBE in the form of solvate, HPLC purity 98.4% by Method 1. Elemental analysis demonstrates that this product contains 0.1-0.8 wt % cesium. The structure of the product was confirmed by x-ray diffraction.

Elemental analysis demonstrates that this product contains 0.1-0.8 wt % cesium. The structure of the product was confirmed by x-ray diffraction. 190.4 g of material from Example 4 was transferred into a dry 10 L flask. Equal weight of activated 4 A 24 molecular sieves powder (191 g), was added. [Aldrich 688363-1KG, sodium aluminosilicate, ?SYLOSIV A4? manufactured by Grace Davidson]. 25 Methyl ethyl ketone (4.2 L) was added to the flask and the mixture was stirred mechanically. 26 Methanol (600 mL) was gradually added into the stirred slurry over a 5 min period. The stirring (800 rpm) was continued for 30 min, at this time nearly all dark brown lumps of material was dissolved. The resulting orange slurry was filtered through Whatman fiberglass GF-B filter disc placed on top of a fine-porosity glass Buchner porosity funnels. The spent molecular sieves were rinsed with additional MEK 0.4 L (2×200 mL) and discarded. The combined filtrates were precipitated by gradual addition of MTBE 10 L with mechanical stirring. The stirring was turned off and the mixture was set aside to precipitate for 30 minutes. The precipitated 27 product was collected by filtration (3 L Buchner funnel), rinsed thoroughly with MTBE 1 L (2×0.5 L) and dried by suction, for about 2 hours, until the Buchner funnel was no longer cold. This provided 184 g of purified sodium salt. To remove the solvent traces, the purified material was treated with wet MTBE. 184 g of the purified sodium salt was combined with 3.3 L of wet MTBE (water saturated MTBE), in a 5 L wide mouth Erlenmeyer and mechanically stirred (200 rpm) for 40 min. The resulting brown solids were collected by filtration. The solids were rinsed with wet MTBE, dried by suction and then thoroughly dried in vacuo overnight (15 hours). The yield was 176.1 g of a coffee-brown granular heavy solid, 98.7% pure by HPLC. (Method 1) This corresponds to 85% overall yield from RuCl3.xH2O (beginning with Example 1). Elemental analysis determined that there was 35 to 750 ppm of cesium remaining.

Na2+2xFe2-x(SO4)3 cathode compound was obtained via classical solid-state synthesis. For the first step, FeSO4 was prepared by heating FeSO4·7H2O at 200?C for 12?h in an Ar/H2 (93:7, by volume ratio) atmosphere. Then the FeSO4 precursor was mixed with off-stoichiometric Na2SO4, and then ball-milled for 12?h in acetone. The Na2+2xFe2-x(SO4)3 material was prepared by heating the mixture at 350?C for 24?h in an Ar atmosphere.

YieldReaction ConditionsOperation in experiment
With sodium ascorbate; In water; at 60℃; for 0.5h; General procedure: The sodium transition metal sulfate hydrates were synthesized via a simple dissolution/evaporation route. Stoichiometric amounts of MSO4·yH2O (Sigma Aldrich, 99%)(where M = Mn, Fe, Co, Ni and Cu, y =1 for Fe and Mn, 5 for Cu, 6 for Ni and 7 for Co) and [7757-82-6]sodium sulfate (Sigma Aldrich, 99%) were dissolved in water. For the Fe containing samples, approximately 50mg of ascorbic acid was added to the solutions in order to prevent oxidation of Fe2+. The solutions were stirred for at least 30min at 60C. The samples were then placed in an oven and dried at 60-110C for Mn, Fe, Co and Cu samples and 130C for Ni (The slightly higher temperature of 130C was required for the Ni samples in order to obtain a single phase sample of the dihydrate; sample treatment <130C yielded a mixture of the dihydrate and tetrahydrate phases).

45% In water; butan-1-ol; at 150℃; for 120h; For a typical synthesis, 0.526 g of iron(III) citrate and 0.568 g of Na2SO4 were dissolved in a mixture with n-butanol (11.2 mL) and distilled water (3.60 mL), and stirred until a homogeneous solution formed. 0.360 mL of 49% HF and 0.325 mL of 85% H2SO4 were then added in the solution drop by drop. Afterwards, the solution was transferred into a PTFE-lined bomb and heated at 150C for 5 days before cooling to room temperature naturally. The resulting pale yellow plate crystals denoted as ??1? were washed with ethanol and distilled water, collected by centrifugation and dried at 353 K. The yields were 45% based on Fe.
