    摘要： A process for producing clear, colorless solutions of branched lithium alkoxides containing 3 to 12 carbon atoms, in a polar reaction solvent, comprising reacting a dispersion of lithium metal having a particle size less than 300 microns with a minimum of 5 mole percent excess over stoichiometric of a branched alkyl alcohol containing 4 to 12 carbon atoms, in a polar reaction solvent as the reaction medium, at a temperature between 50.degree. C. and the boiling point of the solvent in an inert atmosphere.

    摘要： Stable alkali metal trialkylmagnesiate compositions are produced in high yields by simultaneously adding to a stirred dispersion of an alkali metal in an inert liquid hydrocarbon solvent a soluble dialkylmagnesium compound and an alkyl halide. By using a 2-alkyl substituted C.sub.4 -C.sub.18 primary alkyl chloride as the alkyl halide, alkali metal trialkylmagnesiates are produced which have excellent solubility, even at low temperatures, and good thermal stability over a wide range of temperatures. Moreover, the trialkylmagnesiates are soluble in liquid aliphatic or cycloaliphatic solvents in the absence of aromatic solvents or Lewis bases, which makes these compositions especially useful for certain applications, such as catalysts in anionic polymerization, where the presence of aromatic solvents or Lewis bases is undesirable.
