| 摘要 |
<p>The invention concerns a method for making hydrazine in aqueous solution, characterised in that it comprises the following steps which consist in: a) in a reaction medium, preparing 2,2,4,4-tetramethyl-3-pentanone azine by oxidising coupling of 2,2,4,4-tetramethyl-3-pentanone imine in the presence of a catalytic system and oxygen as oxidising agent; b) hydrolysing 2,2,4,4-tetramethyl-3-pentanone azine to obtain hydrazine in aqueous solution and 2,2,4,4-tetramethyl-3-pentanone in the form of an organic phase.</p> |
