What is the reaction between aniline and chlorine?
- Aniline reacts with liquid chlorine to give 2-4-6-trichloroaniline. This reaction is used to prepare phenol or benzene diazonium chloride. Sodium nitrite and dilute hydrochloric acid ( NaNO 2 and HCl ) are mixed to prepare nitrous acid (HNO 2 ). According to the temperature, phenol or benzene diazonium chloride is given.
What happens when sulfuric acid reacts with aniline?
- In the presence of sulfuric acid (pKa = -5.5) aniline will be protonated (anilinium ion pKa = 4.63). That changes the electron-donating amino group to an electron-withdrawing ammonium ion. The reaction will require higher temperature as well.
What happens when Aniline reacts with chloroform under alkaline conditions?
- The reaction of aniline with chloroform under alkaline conditions leads to the formation of Aniline is a primary amine (contains -NH 2 group). When it is treated with chloroform under alkaline conditions, it results in the formation of a bad smelling compound, known by the name isonitrile or carbylamine.
What are the reactions of chlorosulfonic acid?
- This book provides a detailed, up to date account of the reactions of chlorosulfonic acid with aliphatic, aromatic and heterocyclic compounds; reactions with elements and inorganic compounds are also discussed, along with the use of the reagent as a powerful acid catalyst and dehydrating agent.
