Abstract: IMPROVED PROCESS FOR PRODUCING MAGNESIUM UTILIZING ALUMINUM METAL REDUCTANT Magnesium metal is produced by the reaction of aluminum metal with a calcium magnesium aluminate slag or with magnesium oxide in the presence of such slag, wherein the silicon dioxide content of the slag is maintained at five weight percent or less. An excess of aluminum metal relative to the amount of magnesium oxide is employed thereby obtaining a high conversion of the magnesium oxide to magnesium metal.

Abstract: PROCESS FOR PREPARATION OF ORGANIC ACID HALIDE A process for the preparation of organic acid halide such as acetyl chloride by reacting an organic acid anhydride with a silicon halide, such as silicon tetrachloride, under conditions such that the organic acid halide is produced along with silica which is easily separated and disposed of. A Lewis Acid metal halide catalyst is used and superior yields are obtained. The reaction is desirably carried out in the presence of a chlorohydrocarbon solvent in which the metal halide catalyst chosen and the reactants and products are soluble.
