Manufacturing Methods : (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.

Properties and Applications: colourful green light blue. Soluble in cold water and hot water for the blue, soluble in ethanol for green light blue. The strong sulfuric acid for olive tan. In water solution to join sodium hydroxide low temperature discoloration, heat into deep purple.
