PROCEDE DE TRAITEMENT DE LACTAMES |
摘要 |
The invention concerns a method for treating lactams directly derived from the synthesis process, avoiding as far as possible the formation of oligomers. More precisely it concerns a method for treating a lactam from a reaction flux derived from aromatising hydrolysis of an aminonitrile, characterised in that the reaction flux coming out of a hydrolysis reactor is cooled in a time interval of not more than 1 hour at a temperature not more than 150 DEG C before its fractionation.
