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.

Thaum lub sijhawm nitration ntawm aniline cov amino pawg tiv thaiv los ntawm?
Cov nyom rau nitration ntawm aniline tau kov yeej los ntawm kev tiv thaiv ntawm cov amino pawg los ntawm acetylation. Cov acetyl pawg txo cov reactivity ntawm lub nplhaib thiab yog li nws oxidation tsis tshwm sim yooj yim nrog nitric acid HNO3.
Qhov twg hauv qab no muab) aniline los ntawm kev txo cov nitrobenzene?
Kev txo qis ntawm nitrobenzene los ntawm qhov twg hauv qab no reagent muab aniline? C6H5NO2Zn/NH4OH →C6H5NHOH thaum tag nrho lwm cov reagents muab aniline. Qhov twg hauv qab no yog txo cov khoom ntawm nitrobenzene? Teb tiav: Thaum cov tshuaj nitro txo qis, ces amines yog tsim.
Puas tuaj yeem muab amiodarone muab tso rau hauv?
Amiodarone tuaj yeem tswj hwm los ntawm tso rau hauv txoj hauv kev lossis txoj hauv kev. YYuav muab amiodarone io? Nyob rau hauv cov neeg laus, amiodarone tuaj yeem muab tau rau VT / VF lub plawv nres ntawm cov hlab ntsha (IV) / intraosseous (IO) infusion li 300 mg sai bolus ua raws li qhov ntxiv bolus ntawm 150 mg IV / IO yog tias VT lossis VF txuas ntxiv mus.
Puas muab muab tso rau yaj lossis txav chaw?
Thaum nws muaj peev xwm ua tau rau cov neeg ua haujlwm tsiv teb tsaws chaw, qhov kev mob tshwm sim no tsis tshua muaj thiab tuaj yeem zam tau los ntawm kev xaiv tus neeg txhaj tshuaj tsim nyog. Txawm hais tias kev tsiv teb tsaws chaw yog qhov tsis tshua muaj heev, nws yuav muaj peev xwm nce ntxiv thaum cov khoom ua tiav los ntawm tus neeg tsis muaj kev paub lossis tsis muaj peev xwm txhaj tshuaj.
Puas aniline muab cov tshuaj tiv thaiv carbylamine?
N-methyl aniline tsis muab tshuaj carbylamine. Qhov twg tsis muab cov tshuaj tiv thaiv carbylamine? 1. Aniline….. Cov organic compound uas tsis dhau carbylamine kuaj ethyl methyl amine. Yuav ua li cas amines muab cov tshuaj tiv thaiv Carbylamines?
