MANUFACTURE OF EPSILON-CAPROLACTAM
Caprolactam is prepared by a process in which (a) a 5-formylvalerate is reacted with excess ammonia and hydrogen in the presence of an alkanol as a solvent and in the presence of a hydrogenation catalyst under superatmospheric pressure in the liquid phase at from 40 DEG to 130 DEG C., (b) excess amm...
