  1. Amide & imide Polyamine amide Lithium-Imide batteries used as binding materials for electrical motors, transformers and electric appliances

  2. Acid base character

  3. Amphoteric

  4. Preliminary test

  5. General and specific test urea • Biuret reaction: • In dry test tube put few granules of urea then heat on flame until melt and solidify to give white residue. After that cool test tube + 10% NaOH drop by drop to dissolve it and give clear solution then add+ cupper sulphate→purple color

  6. Urea oxalate formation: • Saturated solution of urea + 1ml oxalic acid →urea oxalate as white crystalline ppt. (shiny). • Urea nitrate formation: • Saturated solution of urea + Conc. Nitric acid → urea nitrate as white ppt.

  7. sulphanilamide • Amphoteric property • Acid and base test. • Azo dye test: • 1-Sulph. + dilHcl to dissolve it +NaNO2 → Put in ice • 2-phenol +10 % NaOH→put in ice • After 5 minutes pour 1 on 2→ red orange dye.

  8. phthalimide • Phthaline test: • Phth. + phenol + Conc. H2SO4 heat until fusions after cooling pour it in beaker contain 10 ml of 10% NaOH→ unstable pink color. • Fluorescence test: • Phth. + resercinol +Conc. H2SO4 heat until fusion then cooling and pour it in beaker contain 10 ml 10% NaOH→ reddish brown color give green fluorescence

  9. IR location • Amid stretching band at 1690 cm-1
