Sodium nitrite thiab hydrochloric acid teb nrog aniline los ua diazonium ntsev. Tam sim no, yog tias cov ntsev diazonium no tau tso cai rau cov tshuaj CuCl, ces nws yuav hloov cov diazonium pawg ntawm lub nplhaib uas muaj ntxhiab thiab yuav muab Chlorobenzene ua ib yam khoom.
Qhov twg yuav tsum tau ntxiv kom tau aniline los ntawm chlorobenzene hauv ib kauj ruam?
Chlorobenzene yog soluble hauv dej thiab nws yog volatile nyob rau hauv cov xwm. Kev hloov pauv ntawm aniline rau chlorobenzene yuav siv qhov chaw raws li hauv qab no: a) Aniline yog thawj zaug tshwm sim nrog sodium nitrite thiab hydrochloric acidntawm qhov kub tsis tshua muaj xws li 0−4∘C. Qhov no muab diazonium ion los yog diazonium ntsev.
aniline hloov mus rau Fluorobenzene li cas?
Hint: Aniline tuaj yeem hloov mus ua fluorobenzene ua ntej hloov aniline rau benzene diazonium chloride thiab tom qab ntawd benzene diazonium chloride rau fluorobenzene. Tag nrho cov tshuaj tiv thaiv yuav yog qhov hloov ntawm amine pawg hauv benzene nplhaib los ntawm fluorine atom.
Koj yuav hloov aniline li cas rau bromo benzene?
Thaum aniline kho nrog nitrous acid lossis sodium nitrite thiab HCl ntawm qhov txias txias, nws tau hloov mus rau diazonium ntsev benzene diazonium chloride, uas dhau Sandmeyer cov tshuaj tiv thaiv qhov twg kho nrog CuBr muab Bromobenzene, lossis nws tuaj yeem raug Gatterman cov tshuaj tiv thaiv qhov twg cov ntsev diazonium yog …
Koj hloov aniline rau phenol li cas?
Yog li, pebtuaj yeem hloov aniline rau phenol los ntawm ua ntej kho aniline nrog sodium nitride thiab hydrochloric acid uas muab benzene diazonium ntsev uas nyob rau hauv cov tshuaj tiv thaiv nrog dej muab phenol. Lus Cim: Hauv cov tshuaj tiv thaiv, phenol yog npaj. Yog li, nws yog kev npaj tshuaj tiv thaiv ntawm phenol.
