Acid blue 98 (C.I. 50335) Chemical Properties,Uses,Production
Uses
Acid blue 98 (C.I. 50335)is used as an accessory for the galvanization of copper.
Preparation
N-ethyl-N-benzyl-4-nitrosoaniline?and N-phenyl-2-naphthylaminec condensation and oxidation of the product. Then with N1,N1-diethylbenzene-1,4-diamine and condensation of a mixture of ?N,N-diethyl-4-nitrosobenzenamine and with 65% oleum disulfonated finally converted into sodium salt.
Synthesis
Acid blue 98 (C.I. 50335) [6378-89-8],is synthesized by the following reaction sequence: 2-phenylaminonaphthalene is condensed with 4- nitrosoethylbenzylaniline to give the indamine, which is oxidized with manganese dioxide to the isorosinduline.
