Nickel Chloride, Carbon Disulfide, Ammonium Hydroxide Test
2oAmine
Procedure
Add 1 or 2 drops or 50 mg of unknown to 5 mL of water. If necessary, 1 or 2 drops of conc. HCl may be added to dissolve the amine. To 1 mL of nickel chloride in carbon disulfide reagent in a test tube, add 0.5 - 1 mL of conc. ammonium hydroxide, followed by 0.5 - 1 mL of amine solution.
Positive Test
2o amines- precipitate is a positive test.
Complications
Primary and tertiary amines with secondary amine impurities will yield a positive test.
