PROCESS FOR THE PREPARATION OF ALPHA-ALKYL ACROLEINES |
| 摘要 |
alpha -Alkylacroleins are prepared by reacting an alkanal with formaldehyde and a secondary amine in the presence of a carboxylic, dicarboxylic or polycarboxylic acid in certain molar ratios within a pH range of from 2.5 to 7 and at from 0 DEG to 150 DEG C. The alpha -alkylacroleins which can be prepared by the process described are valuable starting materials for dyes, drugs and pest control agents. |
