This is to make sure the phenylamine is converted to the ammonium salt. This prevents coupling occurring between the diazonium produced, and any unreacted phenylamine. Phenylamine itself has a lone pair on the nitrogen, which would allow unwanted coupling to occur.
The diazotization reaction of 5-amino phthalide involves the conversion of the primary amino group (-NH2) to a diazonium salt (-N2+). This reaction is typically carried out by treating 5-amino phthalide with sodium nitrite (NaNO2) and hydrochloric acid (HCl) at low temperatures. The resulting diazonium salt can further participate in various coupling reactions to form azo dyes or other aromatic compounds.
The reaction between benzoyl chloride and potassium thiocyanate will yield benzoyl thiocyanate as the main product. This reaction involves the replacement of the chlorine atom in benzoyl chloride with the thiocyanate ion from potassium thiocyanate. The reaction is typically carried out in the presence of a base such as pyridine or triethylamine.
Heat equals enthalpy in a chemical reaction when the reaction is carried out at constant pressure.
Aniline reacts with glacial acetic acid to form N-acetylaniline as the primary product. This reaction involves the acetylation of the amino group of aniline by the acetic acid to form the acetylated product. The reaction is usually carried out in the presence of a catalyst like sulfuric acid to facilitate the acetylation process.
The chemical equation for the preparation of ethene from ethanol is: C2H5OH (ethanol) → C2H4 (ethene) + H2O (water). This reaction is typically carried out at high temperatures in the presence of a catalyst such as sulfuric acid.
The diazotization reaction of 5-amino phthalide involves the conversion of the primary amino group (-NH2) to a diazonium salt (-N2+). This reaction is typically carried out by treating 5-amino phthalide with sodium nitrite (NaNO2) and hydrochloric acid (HCl) at low temperatures. The resulting diazonium salt can further participate in various coupling reactions to form azo dyes or other aromatic compounds.
Formalin is produced by mixing formaldehyde gas with water to form a solution of formaldehyde in water. The reaction is generally carried out in the presence of a catalyst, such as a base or an acid, to enhance the speed of the reaction.
Acetanilide can be prepared using aniline and acetic anhydride as reagents. The reaction typically requires the presence of a catalyst, such as zinc chloride, to facilitate the acetylation of aniline to form acetanilide. The reaction is usually carried out in the presence of a base, like sodium acetate, to neutralize the acidic byproduct formed during the reaction.
Benzoyl chloride reacts with aniline to form N-phenylbenzamide. In the reaction, the chlorine atom of benzoyl chloride is replaced by the amino group of aniline. The reaction is often carried out in the presence of a base to help neutralize the hydrogen chloride byproduct.
The reaction between benzoyl chloride and potassium thiocyanate will yield benzoyl thiocyanate as the main product. This reaction involves the replacement of the chlorine atom in benzoyl chloride with the thiocyanate ion from potassium thiocyanate. The reaction is typically carried out in the presence of a base such as pyridine or triethylamine.
