Disclosed are a novel asymmetric azine compound (I) and a method for producing an asymmetric azine compound (I) which is characterized in that an aldehyde compound (III) and hydrazine are reacted in an alcohol solvent at a molar ratio (aldehyde compound (III)):(hydrazine) of from 2:1 to 1:2, thereby obtaining a reaction solution including a hydrazone compound (IV), and then an aldehyde compound (V) is added for a reaction into the thus-obtained reaction solution at a molar ratio (aldehyde compound (V) ):(hydrazone compound (IV)) of from 2:1 to 1:2.
The method can commercially advantageously produce an asymmetric azine compound having a polar group such as a hydroxyl group or a carboxyl group in each molecule. The novel asymmetric azine compound can be obtained by this production method. (In the formulae, R 1 and R 2 each represents a hydroxyl group or a carboxyl group, X 1 to X 8 each represents a hydrogen atom, -C(=O)-OR 3 or the like; and R 3 represents an alkyl group having 1 to 10 carbon atoms or the like.) |
