HNO3 and Conc. H2SO4 ntawm qhov kub thiab txias. -NH2 pawg tam sim no nyob rau hauv aniline yog ib pawg muaj zog activating thiab yog ortho thiab para directing. … Yog li ntawd, thaum lub nitration ntawm aniline yog nqa tawm, nws tsis tsuas yog muab cov khoom nitration tab sis kuj muaj qee cov khoom oxidation.
Yuav ua li cas thaum aniline nkag mus rau nitration?
Thaum muaj nitration hauv aniline, cov Nitric Acid protonates aniline los tsim cov Anilinium ion. Tam sim no txij li thaum lub nitrogen atom tsis muaj ib tug khub rau conjugate, nws tsis muaj mesomeric nyhuv ntawm lub nplhaib, tab sis raws li nitrogen yog tam sim no protonated, nws muaj ib tug siab tsis zoo inductive nyhuv.
Vim li cas aniline yog meta ncaj qha hauv nitration?
Lub anilinium pawg, tsis muaj ib qho dawb electron khub(tied nrog H^+), deactivates lub nplhaib uas muaj ntxhiab mus rau electrophilic hloov, kuj anilinium ion uas yog cov lus qhia meta. Li no nitration ntawm aniline muab meta derivative nrog rau ortho thiab para.
Vim li cas nitration ntawm aniline nyuaj?
Nitration ntawm aniline nyuaj vim aniline tau oxidized rau hauv protonated aniline. Direct nitration ntawm aniline tsis yog ib txoj kev ua tau vim hais tias nitric acid oxidizes feem ntau ntawm aniline muab tarry oxidation khoom nrog rau ib tug me me ntawm cov khoom nitrated.
Vim li cas aniline thiaj muab nitroaniline rau nitration?
Nitration ntawm aniline nyob rau hauv muaj zog acidic nruab nrab kuj muab m-nitroanilinevim. Inspite ntawm substituents nitro pab pawg ib txwm mus rau tsuas yog m-txoj hauj lwm. … Nyob rau hauv acidic (muaj zog) nruab nrab aniline yog tam sim no raws li anilinium ion. Thaum tsis muaj cov neeg hloov pauv nitro ib txwm mus rau m-txoj hauj lwm.
