Process for the preparation of an N-alkyl lactam with improved colour quality |
| abstract |
The invention relates to a process for the preparation of an N-alkyl lactam with improved colour quality, where 0.01 to 10% by weight of a C1-10-alcohol or a compound which releases 0.01 to 10% by weight of a C1-10-alcohol is added to the N-alkyl lactam. Mixture comprising at least 99.0% by weight of an N-alkyl lactam and in the range from 100 to 5000 ppm by weight of a C1-10-alcohol or of an acetal, aminal or an ortho ester which releases in the range from 100 to 5000 ppm by weight of a C1-10-alcohol. |
