In this research, two new azo dyes, 9-(2-Hydroxy-ethoxymethyl)-2-(2-hydroxy5nitrophenylazo)-1,9-dihydro-purin-6-one and 4-(2-Hydroxy-napHthalen-1-ylazo)-N-(5-methyl-isoxazol-3-yl)-benzenesulfonamide, derived from Acyclovir and Sulfamethoxazole was synthesized. The first dye synthesis was started by diazation of acyclovir, then combined with 4-nitrophenol activated with potassium hydroxide 10%, yielding 80%, and its purity was verified by thin layer chromatography (TLC). The second dye synthesis was started by diazation of Sulfamethoxazole then combined with β-naphthol activated with potassium hydroxide 10%, yielding 87%, and its purity was verified by thin layer chromatography (TLC). The identity of the resulting pigments was determined based on spectroscopic methods such as infrared spectroscopy, proton nuclear magnetic resonance spectrum …

In this research synthesized amino is derivative of Schiff-bases by using electrolysis cell. Electrochemical reduction of para-nitroaniline and electrocatalysed condensation have been carried out at zinc electrode and anode from coal in the presence of potassium chloride as supporting electrolyte in water/methanol solution, and in the application of 20V voltage, where interaction is in two stages: the first stage involves the electrochemical reduction of nitro group and get the amino and the second phase also, azo Schiff was synthesized between para-nitroaniline and metoxybenzealdehyde by electrolysis method, which was supplied with a zinc electrode as cathode to perform electrochemical reduction in …
