purpose of this lab is to synthesize Lidocaine from 2‚6-dimethylaniline‚ using diethyl amine‚ 2-chloroacetyl chloride‚ acetic acid‚ and toluene. The Lidocaine was made by adding 2‚6-dimethylaniline to 2-chloroacetyl chloride in acetic acid. Sodium acetate is added in order to make the compound soluble. The product is dried‚ then treated with diethyl amine and toluene. This is refluxed using a water-cooled reflux condenser. The vapor is condensed by the cold water as the compound is being heated. A

TESTS KELLER-KILIANI TEST FOR DIGITOXOSE The test consists of boiling about 1 g finely powdered digitalis with 10 ml 70 % alcohol for 2 to 3 minutes. The extract is filtered. To the filtrate is added‚ 5 ml water and 0.5 ml strong solution of lead acetate. Shake well and separate the filtrate. The clear filtrate is treated with equal volume of chloroform and evaporated to yield the extractive. The extractive is dissolved in glacial acetic acid and after cooling‚ 2 drops of ferric chloride solution
