Cov tshuaj lom hais tawm yog ib txoj hauv kev tseem ceeb rau kev npajNitroso r ntsev, tshwj xeeb yog tsim nyog rau cov tebchaw uas muaj cov pab pawg uas muaj ntxhiab amine. Cov txheej txheem kev hloov pauv no cuam tshuam txog cov neeg muaj kuab lom nrog cov ntsev ua si nrog ntau yam nucleophilic reagents los tsim cov nitroso kawg.
1. Cov ntsiab cai yooj yim
Cov tshuaj tiv thaiv diazotization yog cov tshuaj tiv thaiv ntawm cov khoom siv uas muaj ntxhiab tsw thiab nitrite nyob rau hauv tsawg kub thiab acidic tej yam kev mob, tsim diazonium ntsev. Diazo ntsev yog cov khoom lag luam nruab nrab uas nquag heev thiab tuaj yeem hnov cov tshuaj xyuas thiab tuaj yeem ua ntxiv nrog ntau nucleophilic reagents.
2. Tshuaj Hniav
(1) Diazotization cov tshuaj tiv thaiv
Ar - nh₂ + hnoos → →- n₂⁺x⁻ + h₂o
Ntawm lawv, ar sawv cev rau lub nplhaib muaj ntxhiab, thiab x ⁻ sawv cev Anions (xws li cl ⁻, br ⁻, thiab lwm yam).
(2) cov kev hloov pauv nrog nucleophilic reagents (siv phenols ua piv txwv)
Ar - n₂⁺x⁻ + phoh → ar -} tsis muaj + phx
Ntawm lawv, Phooj tsawg sawv cev phenyl, thiab PHX yog phenolic Saloldy los ntawm cov tshuaj tiv thaiv ntawm phenol thiab diazonium ntsev.
3. Cov ncauj lus kom ntxaws
Firstly, haum uas muaj ntxhiab amines yuav tsum tau npaj ua ntej pib cov ntaub ntawv. Tus qauv ntawm cov mines uas txiav txim siab cov khoom ntawm lub txiaj ntsig Nitroso R.
Dissolve sodium nitrite (nano2) Hauv cov dej uas tsim nyog kom tau txais cov tshuaj aqueous ntawm sodium nitrite. Tom qab, maj mam ntxiv sulphuric acid los hloov sodium nitrite rau hauv nitrite (hno2). Cov kauj ruam no yuav tsum nruj tswj cov py tus nqi, feem ntau ntawm 2-4.
Dissolve cov duab uas muaj ntxhiab amine nyob rau hauv dilute acid thiab txias rau 0-5℃(hauv dej khov nab kuab). Tom qab ntawd, maj mam ntxiv nitrous acid daws thaum stirring. Kauj ruam no yog exothermic cov tshuaj tiv thaiv, yog li ntawd nws yog qhov tsim nyog los tswj cov mob nrawm los tiv thaiv kev kub ntxhov hauv lub zos. Tom qab dripping, txuas ntxiv nplawm rau ib lub sijhawm los ua kom ua tiav cov tshuaj tiv thaiv.
Tom qab cov tshuaj tiv thaiv ua tiav, txias cov tshuaj tiv thaiv sib tov rau chav sov thiab rho tawm cov ntsev uas tsim nyog (xws li ether, acetone, thiab lwm yam). Tom qab rho tawm, cov organic theem yog sib cais los ntawm theem aqueous kom tau txais ib theem organic muaj cov kua txiv diazonium.
Rov qab ua cov diazonium ntsev tau txais nyob rau hauv cov kauj ruam dhau los nrog tsim nyog nucleophilic reagents (xws li phenols, thiols, thiab lwm yam) nyob rau hauv cov xwm txheej tsim nyog los tsim kom muaj qhov tseebNitroso r ntsevCov. Cov tshuaj tiv thaiv rau cov kauj ruam no (xws li qhov ntsuas kub (xws li cov nqi, thiab lwm yam) yuav tsum tau hloov kho raws li lub nucleophilic reagents.
