Direct Green 6 - Production method
using 4,4 '-diaminoazobenzene, h acid, phenol and p-aminophenol as raw materials, the 4,4'-diaminoazobenzene is first double nitrided, coupled with h acid, then coupled with phenol for the second time, at the same time, the p-aminophenol is diazotized, and finally the product is obtained by coupling with the above three azo compounds. The finished product is salted out, filtered and dried.
