Process For Producing Magnesium Utilizing Aluminum Metal Reductant
US Patent:
4066445, Jan 3, 1978
Filed:
Feb 28, 1977
Appl. No.:
5/772652
Inventors:
James D. Johnston - Baton Rouge LA
Robert N. Sanders - Baton Rouge LA
James M. Wood - Baton Rouge LA
Robert N. Sanders - Baton Rouge LA
James M. Wood - Baton Rouge LA
Assignee:
Ethyl Corporation - Richmond VA
International Classification:
C22B 4500
US Classification:
75 67R
Abstract:
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.
Process For Preparation Of Organic Acid Halide
US Patent:
4136113, Jan 23, 1979
Filed:
Dec 28, 1977
Appl. No.:
5/865219
Inventors:
James D. Johnston - Baton Rouge LA

Robert N. Sanders - Baton Rouge LA
Richmond M. Starrett - Baton Rouge LA
Robert N. Sanders - Baton Rouge LA
Assignee:
Ethyl Corporation - Richmond VA
International Classification:
C07C 5158
US Classification:
260544Y
Abstract:
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 such the organic acid halide is produced along with silica which is easily separated and disposed of. Preferred conditions include use of a solvent, use of a catalyst and additional process reaction steps whereby by-products are converted to additional organic acid halide and easily disposable waste products.
