Method for the preparation of pure lactam from its primary solutions in an organic solvent |
| abstract |
A method for the preparation of pure lactam is disclosed wherein a primary solution of the lactam in an organic phenolic solvent is supplemented by a compound miscible with the solution which is compatible with the primary solvent and is a solvent for the primary solvent but not for the lactam and susceptible of giving rise to precipitation of the lactam, the lactam being then separated from the mixture of the primary solvent and the compound which is a solvent for said primary solvent. |
