Method for the continuous synthesis of monoalkyl-hydrazines with a functionalised alkyl group |
摘要 |
The invention relates to a method for the continuous synthesis of monoalkyl-hydrazines with a functionalised alkyl group. The inventive method is characterised in that it comprises a step consisting in demixing a solution containing the synthesised monoalkyl hydrazine, by reacting an anhydrous amine with monochloramine, in an organic phase and an aqueous phase with the addition of anhydrous sodium hydroxide. The invention can he used to obtain perfect selectivity in relation to monoalkyl-hydrazine without the presence of the di- and tri-substituted forms thereof. According to the invention, the starting amine which has not reacted is collected and reused directly without any additional treatment.
