| 20110137027 | METHOD FOR PREPARING LACTAMES, COMPRISING A PHOTONITROSATION STEP, FOLLOWED BY A BECKMANN TRANSPOSITION STEP - The invention relates to a method for preparing lactames, according to which a photonitrosation of a cycloallcane is carried out using nitrosyl chloride (NOCI). According to the invention, said photonitrosation is carried out by means of LEDs emitting a monochromatic light. The method according to the invention can also include a step comprising Beckmann transposition/dechlorination of the oxime hydrochloride generated during said phonitrosation, preferably carried out in a glass microreactor. | 06-09-2011 |
