Filed: 1926-05-10
Abstract: 269,345. Johnson, J. Y., (1. G. Farbenindustrie Akt.-Ges.). May 10, 1926. Carbonyl processes; molten metals, removing impurities from by exhaustion.-Pure iron is produced by melting or sintering iron obtained by the decomposition of iron carbonyl. This iron is obtained in a spongy condition, sometimes contaminated with carbon and oxygen, which are removed by sintering or melting the iron, excluding the air and other oxidizing gases, preferably after compressing the iron. The melting may be carried out in vacuo, and the molten metal may be finally exposed to an inert gas, such as nitrogen or argon, at ordinary or higher pressures. The melting may be carried out, immediately after producing the spongy iron, by arranging a bath of molten iron below the reaction vessel employed for the decomposition of the carbonyl.
