Production method for aliphatic aromatic C8 to C18 ketones, cyclanic aromatic C10 to C25 and aromatic C13 to C25 as well as aromatic aldehydes from C7 and more

摘要

Production method for aromatic, aliphatic aromatic ketones and cyclanic aromatic ketones as well as aromatic aldehydes is performed from aromatic, aliphatic and aromatic, cyclanic and aromatic acids or alkylesters thereof with C1 to C5 alkyls, particularly in situ made on catalyst of esters and aqueous steam, or of the acids and alcohols under the temperature 250 to 650 °C and pressure 0.05 to 5 Mpa in gaseous or steam phase. The catalyst is synthetic, or it is a by-product of the metallurgical production, eventually iron ore or other ores, eventually baked clay. With the raw material other additional substances can be brought in, such as water, inert gases and oxygenous gases and oxygenous organic compounds.
