1-Iodo-2-nitrobenzene, uas muaj CAS naj npawb ntawm 609-73-4, yog cov organic compound.
Raws li txoj cai, nws yog ib qho iodine atom thiab ib pawg nitro txuas ntawm ib qho chaw tshwj xeeb (ortho) ntawm lub nplhaib benzene. Cov qauv tshwj xeeb no muab cov khoom tshwj xeeb rau nws. Nyob rau hauv cov nqe lus ntawm lub cev muaj zog, nws feem ntau tshwm sim raws li lub teeb daj mus rau daj crystalline los yog powdery khoom nrog ib tug tej yam ntau yam ntawm melting thiab boiling ntsiab lus, nrog ib tug melting point ntawm txog 40 - 45 ° C thiab ib tug kuj kub kub taw tes, txwv los ntawm tej yam. xws li lub zog intermolecular.
Hais txog cov khoom siv tshuaj, vim muaj zog electron rho tawm ntawm nitro pawg thiab cov yam ntxwv ntawm cov iodine atoms, nws tuaj yeem koom nrog ntau yam kev cuam tshuam ntawm cov organic synthesis. Piv txwv li, hauv kev hloov pauv nucleophilic cov tshuaj tiv thaiv, iodine atoms yog qhov yooj yim tawm mus, yog li lwm pab pawg ua haujlwm tuaj yeem nkag mus rau hauv txoj haujlwm no ntawm lub nplhaib benzene txhawm rau tsim cov txheej txheem organic molecular, muab cov khoom nruab nrab tseem ceeb rau kev siv tshuaj, cov ntaub ntawv tshawb fawb thiab lwm yam. teb.
Nyob rau hauv cov nqe lus ntawm kev npaj, nws yog ib qho uas yuav tsum tau siv cov coj nitrobenzene derivatives raws li cov khoom pib, thiab qhia iodine atoms los ntawm halogenation cov tshuaj tiv thaiv, thiab cov txheej txheem tshuaj tiv thaiv yuav tsum nruj me ntsis tswj cov tshuaj tiv thaiv tej yam kev mob, xws li kub, reagent ntau npaum, tshuaj tiv thaiv lub sij hawm, thiab lwm yam. ., los xyuas kom meej lub selectivity thiab purity ntawm lub hom phiaj cov khoom.
Nws yog feem ntau siv nyob rau hauv lub teb ntawm cov tshuaj zoo nyob rau hauv industrial daim ntaub ntawv, raws li ib tug tseem ceeb lub tsev thaiv rau lub synthesis ntawm tej bioactive molecules, thiab pab nyob rau hauv kev tshawb fawb thiab kev loj hlob ntawm cov tshuaj tshiab; Nyob rau hauv lub teb ntawm cov ntaub ntawv, nws koom nyob rau hauv lub synthesis ntawm functional polymer cov ntaub ntawv thiab endows lawv nrog tshwj xeeb optoelectronic zog, uas muab ib tug indispensable foundation rau txoj kev loj hlob ntawm niaj hnub science thiab technology.
Nws yuav tsum tau muab sau tseg tias lub compound muaj ib tug tej yam toxicity, thiab nruj heev tshuaj lom neeg soj ntsuam kev ruaj ntseg cov cai yuav tsum tau ua raws li thaum lub sij hawm ua hauj lwm thiab cia, tsis txhob sib cuag nrog daim tawv nqaij, qhov muag, thiab nqus tau pa ntawm nws cov plua plav, kom tsis txhob muaj kev puas tsuaj rau tib neeg lub cev.
