SQM Nitratos (Chile) operates two sodium nitrate plants in northern Chile Pedro de Valdivia and Mama Elena, about 30 km distant from one another. The caUche is mined in open-pit areas. A solar evaporation plant, Coya Sur, Hes in between. A flow sheet of the processing operations for sodium nitrate production is shown in Figure 2. 

As of 1996 world production of sodium nitrate was about 520,000 metric tons annually. Of this quantity, some 450,000 t (86%) are produced in Chile from natural deposits by SQM Nitratos and distributed worldwide by several affOiates, eg, Chilean Nitrate Corporation in the United States and Nitrate Sales International in Belgium. The remainder, ca 70,000 t, is manufactured mainly in Europe, Japan, and Russia, generally as a by-product of nitric acid production. Additionally, China is known to manufacture some unknown but significant volumes of sodium nitrate for domestic use. 

Technical Grades. Chile s SQM Nitratos is the largest producer of technical-grade NaNO, making ca 170,000 t/yr. About 70,000 t/yr are manufactured in countries such as Germany (BASF), Japan (Mitsubishi), and others. Sodium nitrate has not been manufactured in the United States since Olin Corporation stopped production in 1988.

The highly ionic thaHic nitrate, which is soluble in alcohols, ethers, and carboxyhc acids, is also a very useful synthetic reagent. Oxidation of olefins, a,P-unsaturated carbonyl compounds, P-carbonyl sulfides, and a-nitrato ketones can aH be conveniently carried out in good yields (31,34—36). 

The nitrato compound is a weak electrolyte in acetonitrile solution. 

The complex coordination chemistry of Pb" is also beginning to be actively explored and some unusual stereochemistries are emerging. Thus, the mononuclear ( ) -nitrato)bis(phenanthrolene)(A-thiocyanato) complex [Pb(phen)2(NCS)( ) -NO3)] has 7-coordinate Pb" with a large vacancy... 

N2O4 has been extensively studied as a nonaqueous solvent system and it is uniquely useful for preparing anhydrous metal nitrates and nitrato complexes (p. 468). Much of the chemistry can be rationalized in terms of a selfionization equilibrium similar to that observed for... 

The nitrate group, like the nitrite group, is a versatile ligand and numerous modes of coordination have been found in nitrato complexes. ° The uncoordinated N03 ion (isoelectronic with BF3, B03 , C03 , etc.) is planar with N-O near 122 pm this value...

(a) [CefNOa) ] " the Ce" is surroundecl by 12 oxygen atoms from 6 bidentate nitrate ions in the form of an icosahedron (in each case the third oxygen is omitted for clarity). Note that this implies an octahedral disposition of the 6 nitrogen atoms, (b) [Ce(N03)4(0PPh3)2].
