Azine, cleavage method of hydrazone bond

摘要

The present invention relates to a method for producing a hydrated hydrazine, a substituted hydrazine, or an amino compound, the method being characterized in that by hydrolyzing a ketone azine, a hydrazone or a Schiff base compound in the presence of carbon dioxide in a subcritical, supercritical or liquid state, obtained are: a ketone; and a hydrated hydrazine or substituted hydrazine, or carbazic acid or a substituted carbazic acid, or a carbonyl compound and an amino compound, or a carbamic compound or a substituted carbamic acid.
