Participants

Reaction Steps

4-Anilino-2-methoxybenzenediazonium hexafluoroarsenate was prepared by reacting 4-anilino-2-methoxybenzenediazonium chloride with hexafluoroarsenic acid in water. The resultant produt gave a 90% yield which melted at 167° (dec.) and assayed over 95%. When the product was recrystallized from methanol it melted at 171.5° (dec.); analysis 9.69%, 9.76% N; calculated 10.12% N. The product has a maximum molar absorptivity at 365 mμ of 31,900 in methanol. Film bases of cellulose triacetate and cellulose diacetate film were coated with the following solution:2-Butanone 50 mlMethanol 50 ml5-Sulfosalicyclic acid 1.75 g.3-Hydroxy-2-naphth-o-toluidide 0.6 g.N-Benzylacetoacetamide 0.4 g.Methyl Violet B (4 g) in 1 ml 1000 ml of 2-methoxyethanol4-Anilino-2-methoxybenzenediazonium 2.0 g. hexafluoroarsenate
