salt in a large beaker add preheated liquid ethox ana 50 liquid slowly transfer the naphthionic acid diazonium salt from stage 2 to the beaker containing the liquid ana 50 and agitate the mixture for about 30 minutes neutralize the reaction mass with triethanolamine to ph 7 5 7 8 agitate the reaction mass for at least 5 hours the process of formulating rinsable violet dye according to the present invention comprises five stages 1 condensation 2 first oxidation 3 second oxidation 4 neutralization and dilution and 5 filtration in a large flask add polyethoxylated aniline s10 800 g formaldehyde 61 g as 37 and sulfuric acid 13 g as 96 heat the reaction mass to 125 u00b0 c and maintain that temperature with agitation for 20 hours cool the material from stage 1 down to 85 u00b0 90 u00b0 c then add polyethoxylated aniline s10 400 g and sodium iodate 50 g as 98 heat the mixture to 125 u00b0 c and maintain temperature for 6 8 hours check the absorbance of the developed violet color and continue to mix until expected absorbance is obtained cool stage 2 material down to 85 u00b0 95 u00b0 c then add sodium iodate 50 g as 98 and preheated liquid benzene sulfonic acid 126 g as 94 heat the mixture to 125 u00b0 c and maintain the temperature for 6 8 hours check the absorbance of the developed violet color and continue to mix until expected absorbance is obtained cool the reaction mass from stage 3 to 60 u00b0 65 u00b0 c then add deionized water 200 ml and triethanolamine 200 g agitate for 2 hours then stop.
