摘要:Degradation acids obtained in the synthesis of carboxylic acids, in particular dicarboxylic acids, having from 8 to 16 carbon atoms may be isolated by separating the degradation acids in the form of a solid from the crude reaction mixture, then washing the degradation acids in the form of an oil with water at an elevated temperature. The resulting degradation acids having low oxidant and metal contents, and the metal catalyst may be recirculated back to the process.

标题:Synthesis of 12-aminododecanoic acid

摘要:A process for producing 12-oxododecanoic acid oxime, a novel compound which can be used as a raw material in several industrial processes, is disclosed. The disclosed process relies on a renewable raw material, vernolic (cis-12,13-epoxy-cis-9-octadecenoic) acid. The process utilizes readily available chemical technology which does not involve the use of gaseous hydrocarbon or petrochemical-base feedstock. Hydrogenation of vernolic acid produces 12,13-epoxystearic acid, which can be oxidized with periodic acid to give 12-oxododecanoic acid, which can be reacted with hydroxylamine to yield 12-oxododecanoic acid oxime. A process for reducing the 12-oxododecanoic acid oxime to yield 12-aminododecanoic acid, the monomer for nylon-12, is also disclosed.

摘要:A process for preparing methanol from a carbon-containing feedstock by producing synthesis gas therefrom in a synthesis gas production unit, converting the synthesis gas to methanol in a methanol synthesis unit and working up the reaction mixture obtained stepwise to isolate the methanol, wherein the carbon monoxide, carbon dioxide, dimethyl ether and methane components of value from the streams separated off in the isolation of the methanol are combusted with an oxygenous gas, and the carbon dioxide in the resultant flue gas is separated off in a carbon dioxide recovery unit and recycled to the synthesis gas production unit and/or to the methanol synthesis unit.
