| titleOfInvention | Asymmetric azine compound and method for producing the same |
| abstract | 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 liquid containing a hydrazone compound (IV), and then an aldehyde compound (V) is added for a reaction into the thus-obtained reaction liquid 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 hydroxy group or a carboxyl group in each molecule. The novel asymmetric azine compound can be obtained by this production method. (In the formulae, R1 and R2 each represents a hydroxy group or a carboxyl group; X1-X8 each represents a hydrogen atom, -C(=O)-OR3 or the like; and R3 represents an alkyl group having 1-10 carbon atoms, or the like.) |
