Preparation

(a) 3-Nitrobenzaldehyde?and N,N-diethylbenzenamine (2 Moore) condensation, then reduction, then the amino diazotization and then translate into hydroxyl compound, and then two stlfonation, finally will product into calcium salt, and segregation and oxidation; (b)3-Hydroxybenzaldehyde and N,N-diethylbenzenamine (2 Moore) condensation, and then two stlfonation, into calcium salt and oxidation. The dyes can also be as sodium salting out.
