Abstract:
The present invention relates to a process for preparing C 4 -C 15  lactams, in which a C 1 -C 10 -alkyl nitrite is reacted with a C 4 -C 15 -cycloalkane and is illuminated with a light-emitting diode during the reaction. This forms a C 4 -C 15 -cyclohexanone oxime which is then converted further to a C 4 -C 15  lactam; the C 1 -C 10  alcohol formed is recycled into the preparation of the C 1 -C 10 -alkyl nitrite.

Claim (Index 13):
A process for preparing C 4 -C 15  lactams, comprising the steps of:\n a) converting a first mixture (M1) comprising a C 1 -C 10  alcohol, nitrogen oxides and oxygen to obtain a C 1 -C 10 -alkyl nitrite, b) converting a second mixture (M2) comprising the C 1 -C 10 -alkyl nitrite obtained in step a) and a C 4 -C 15 -cycloalkane to obtain a first product mixture (P1) comprising a C 4 -C 15 -nitrosocycloalkane, a dimeric C 4 -C 15 -nitrosocycloalkane, a C 4 -C 15 -cycloalkanone oxime and a C 1 -C 10  alcohol,\n wherein the second mixture (M2) is illuminated during the conversion with a light-emitting diode that emits light having a wavelength in the range from 300 to 500 nm, \n c) preparing the C 4 -C 15  lactam by conversion of the C 4 -C 15 -cycloalkanone oxime obtained in step b) in the presence of a catalyst by one of the following steps:\n c1) separating the C 1 -C 10  alcohol from the first product mixture (P1) obtained in step b) to obtain a second product mixture (P2) comprising the C 4 -C 15 -cycloalkanone oxime,\n recycling the C 1 -C 10  alcohol removed into the first mixture (M1) in step a) and \n converting the C 4 -C 15 -cycloalkanone oxime present in the second product mixture (P2) in the presence of the catalyst to obtain the C 4 -C 15  lactam, \n \n or \n c2) converting the C 1 -C 15 -cycloalkanone oxime present in the first product mixture (P1) in the presence of the catalyst to obtain a third product mixture (P3) comprising the C 4 -C 15  lactam and the C 1 -C 10  alcohol,\n removing the C 1 -C 10  alcohol present in the third product mixture (P3) to obtain the C 1 -C 15  lactam and \n recycling the C 1 -C 10  alcohol removed into the first mixture (M1) in step a).
