Introduction The corrosive attack of nitric acid on copper is mainly due to the nitrous acid formed by the reaction between copper and nitric acid. The reaction is conditioned by: the concentration of the acid; temperature; the presence of nitrous acid; and the solubility of the reaction ...
Here, the aniline reacts with nitrous acid to form benzenediazonium chloride (PhN2Cl).Step 2: Reduction of Diazonium Salt3. Reduce the Diazonium Salt: The diazonium salt (PhN2Cl) is then reduced to form phenylhydrazine. This can be accomplished using zinc (Zn) and hydrochloric acid (HCl...
The reaction with nitrous acid produces a diazonium salt, from which a series of benzene derivatives and azo compounds can be prepared. aniline is an important chemical raw material, the production of more important products up to 300 kinds, mainly used in MDI, dye industry, medicine, rubber...
ReactionA primary aromatic amine, aniline is a weak base and forms salts with mineral acids such as aniline hydrochloride. PKb = 9.30, 0.2mol aqueous solution PH value 8.1. In acidic solution, nitrous acid converts aniline into a diazonium salt that is an intermediate in the preparation of ...
In 0.1M of hydrochloric acid medium, aniline diazotizes with nitrous acid, which is then coupled with N-(1-naphthyl)-ethylenediamine at the same acidity. The azo-dye formed is collected on a 0.45渭m nitrocellulose filter at pH 5.0 of acetate buffer solution in the presence of surfactant ...
Various metals react with the amino group to form metal anilides; and hydrochloric, sulfuric, or phosphoric acid salts of aniline are important intermediates in the dye industry. Important reactions include n-alkylation, ring alkylation, acylation, condensation, cyclization, reaction with nitrous acid,...
To synthesize p-Nitrobenzene and p-Cyano benzoic acid starting from aniline and toluene respectively, we can follow these steps: Synthesis of p-Nitrobenzene from Aniline: 1. Formation of Diazonium Salt: - Start with aniline (C6H5NH2). - Treat aniline with nitrous acid (HNO2), which can be...
2. React with Nitrous Acid: To perform diazotization, aniline is treated with nitrous acid (HNO2), which can be generated in situ by mixing sodium nitrite (NaNO2) with hydrochloric acid (HCl) at a low temperature (0 to 5°C).3. Formation of Diazonium Salt: The reaction leads to ...
6.9 parts of sodium nitrite are simultaneously run in in the form of a 2-N. solution so that with the aid of potassium iodide starch paper free nitrous acid is always detectable. The diazotization is performed at a temperature of 30 0° C. to 5° C. Finally a clear diazo-solution ...
