Write circuit receipt of sulfanilic acid atsetanilida.Napisat mould equation and the title product,


Write circuit receipt of sulfanilic acid atsetanilida.Napisat mould equation and the title product, which will confirm the acidic properties of sulfanilic mould acid and its amida.Kakie of these substances a) is a strong acid; b) has amphoteric properties? The answer is explained by the example of one of the proposed substance that exhibits amphoteric properties, write scheme and call it a product of the interaction of alkali.

The answer is explained by the example of one of the proposed substance that exhibits amphoteric properties, write scheme and call it a product of the interaction of alkali. However, the original method mould for the synthesis of sulfanilic acid. But, just so - so be it: S6H5-NH-COCH3 - (H2SO4, -H2O) -> HSO3-C6H4-NH-COCH3 - (H2O, t 0, -CH3COOH) -> HSO3-C6H4- NH2 Acidic acid properties: NH2-C6H4-SO3H + NaHCO3 ----> NH2-C6H4-SO3Na + CO2 + H2O (n-aminobenzolsulfonat sodium) amide acidic properties: mould NH2-C6H4-SO2-NH2 + NaOH ----> NH2-C6H4-SO2-NH-Na + H2O (n-aminobenzolsulsulfamid sodium) Acid advantageously exhibits acidic properties, because there is a zwitterion NH3 + -C6H4-SO3 -, which is a very weak base. Amide exhibits amphoteric properties, reacts with alkalis like (See above.) mould And strong acids: mould NH2-C6H4-SO2-NH2 + HCl ----> [NH3 + -C6H4-SO2-NH2] mould Cl - (n aminobenzolsulsulfamid hydrochloride) However, both acidic and basic properties are manifested rather weak.

This way, the second method
Was mind reaction with chlorosulfonic acid (to form the corresponding sulfonyl chloride), and then hydrolysis. mould That's right, the second way normal way - I like it. Even better - isomers certainly cleaner. I was excited as a person close to the production - and figured the cost of sulfanilic acid, aniline and acetanilide. In the first edition of the post I put a few more specific about this. But then corrected - for, in terms of pure chemistry is a perfectly mould acceptable way of synthesis. Top

How syntheses I ruined the teacher ... But the development goes. - You are so expensive reagents! Remake!
