  1. AMINES & AMINES SALTS

  2. Aniline Aniline hydrochloride Aniline sulphate 1ry amine All aromatic Solid, fine powder Liquid, oily, true White green (( gray)) Reddish brown White creamy color Fishy odor Characteristic odor

  3. Ignition test: Inflammable, luminous, smoky Volatilization Melting No change No change No residue All the compounds are aromatic

  4. Immiscible soluble BlueRed Miscible in large amount Strong effervescence Basic compound .: The compounds are Strong acid

  5. Not done ( for solid only) No reaction Fishy odor Salt + H2O + 30% NaOH oily droplet + white ppt + fishy odor No reaction Not done 1 drop aniline + dil. HCl + 2dps FeCl3 salt + H2O + 2dps FeCl3 No reaction No reaction Green color Green color Aniline + 2 dpsConc. H2SO4 White ppt of aniline sulphate No reaction Not done

  6. 1. Azo dye formation test: 1 drop aniline (red color) + dil.HCl (until dissolve) + NaNO2 (sod. Nitrite solution) until faint pale yellow color {Diazonium salt formed} (1) It is unstable because that we must put it in ice, without ice it will decompose few phenol + 10% NaOH (until phenol dissolved) (2) Add (1) on (2) gradually Orange – red ppt or color 2. Acetylation test: 5 ml aniline + 20ml acetic anhydrideReflux 20 min. Pour in ice White ppt of anilide.

  7. AgNO3 test: BaCl2 test: Aniline HCl+ Distilled H2O + Dil. HNO3 + 2 dps AgNO3 ((silver nitrate)) Aniline sulphate + Distilled H2O + Dil. HCl + 1 dps BaCl2 White crudyppt of AgCl White ppt of BaSO4 3500 – 3100 cm -1 -NH stretching band (function gp) > 3000 cm -1 CH aromatic stretching band
