Process for producing high-purity N-vinylcarboxamides |
| abstract |
Disclosed is a process for producing high-purity N-vinylcarboxamides comprising: (A) a step of dissolving a crude N-vinylcarboxamide in an alcohol having 1 to 3 carbon atoms, the crude N-vinylcarboxamide containing 50 to 97% by mass of an N-vinylcarboxamide; (B) a step of adding an aliphatic hydrocarbon having 5 to 10 carbon atoms to the composition obtained in the step (A) to precipitate a crystal of the N-vinylcarboxamide; and (C) a step of separating the crystal of the N-vinylcarboxamide precipitated in the step (B). |
