Verfahren zur Herstellung von Adipinsaeure

Cyclohexanol and cyclohexanone are obtained by oxidising cyclohexane with molecular oxygen for an initial period of 15-45 minutes at 140-170 DEG C. and then for a longer period at a lower temperature of 120-140 DEG C., the pressure being maintained between 75 and 500 p.s.i.g. Adipic acid may be prod...

Zusammenfassung:Cyclohexanol and cyclohexanone are obtained by oxidising cyclohexane with molecular oxygen for an initial period of 15-45 minutes at 140-170 DEG C. and then for a longer period at a lower temperature of 120-140 DEG C., the pressure being maintained between 75 and 500 p.s.i.g. Adipic acid may be produced by a subsequent catalytic oxidation stage with molecular oxygen or nitric acid.
