| abstract |
The present invention relates to a method for producing 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 exposed during the reaction by means of a light-emitting diode. The thus produced C 4 -C 15 cyclohexanone oxime is then further reacted to a C 4 -C 15 lactam, and the formed C 1 -C 10 alcohol is recycled in the production of the C 1 -C- 10 alkyl nitrite. |
