    摘要: A process for producing dispersions of atmospherically stable, coated alkali metal particles and atmospherically stable, coated alkali metal powders by agitating a mixture of molten alkali metal in a hydrocarbon oil at dispersion speeds, optionally in the presence of a dispersing agent, contacting the molten alkali metal-hydrocarbon oil dispersion, above or below the surface of the dispersion, with up to 3 weight percent anhydrous carbon dioxide while agitating the dispersion for at least 1 minute. The dispersion in oil can be used directly in chemical reactions. The bulk of the oil can be removed from the dispersions to produce oil wet particles, the oil wet particles car be washed with a low boiling hydrocarbon to produce hydrocarbon wet particles which can be dried to produce atmospherically stable powders of coated metal particles. The dispersed particles in oil, the oil wet particles, the hydrocarbon wet particles and the atmospherically stable powders can each be used in chemical reactions. After washing and drying, the process produces lithium powders having a surface coating composition containing 0.1-0.3 atom percent lithium, 0.3-0.4 atom percent carbon, and 0.3-0.5 atom percent oxygen. The products of the invention may be used to synthesize organometallic compounds, esp. n-butyl lithium and sec-butyl lithium, having low color and low soluble inorganic chloride levels.
