Latest Patents
One of his latest patents is a process for the preparation of organic acid halide. This innovative method involves reacting an organic acid anhydride with a silicon halide, such as silicon tetrachloride, under specific conditions to produce organic acid halides like acetyl chloride. The process also generates silica, which can be easily separated and disposed of. Preferred conditions for this process include the use of a solvent, a catalyst, and additional reaction steps that convert by-products into more organic acid halides and easily disposable waste products. Another significant patent involves the production of magnesium utilizing aluminum metal as a reductant. In this process, magnesium metal is produced by reacting aluminum with calcium magnesium aluminate slag or magnesium oxide, while maintaining the silicon dioxide content of the slag at five weight percent or less. By employing an excess of aluminum relative to magnesium oxide, a high conversion rate of magnesium oxide to magnesium metal is achieved.
