I-1-Iodo-2-nitrobenzene, enenombolo ye-CAS ye-609-73-4, i-organic compound.
Ngokwesakhiwo, yiathomu ye-iodine kunye neqela le-nitro elidityaniswe kwindawo ethile (ortho) kwiringi ye-benzene. Esi sakhiwo esiyingqayizivele sisinika iipropati ezikhethekileyo zeekhemikhali. Ngokweempawu ezibonakalayo, ngokuqhelekileyo kubonakala njengekristale ekhanyayo etyheli ukuya kumthubi okanye umgubo oqinileyo kunye noluhlu oluthile lokunyibilika kunye namanqaku abilayo, kunye nendawo yokunyibilika phakathi kwe-40 - 45 ° C kunye neqondo eliphezulu lokubilisa, elilinganiselwe ngenxa yezinto. njengamandla e-intermolecular.
Ngokweempawu zemichiza, ngenxa yeepropathi ezinamandla zokurhoxiswa kwe-electron zamaqela e-nitro kunye neempawu zokusabela ezisebenzayo zeathom ze-iodine, inokuthatha inxaxheba kwiintlobo ezahlukeneyo ze-organic synthesis reactions. Ngokomzekelo, kwi-nucleophilic substitution reactions, i-athomu ye-iodine kulula ukuyishiya, ukwenzela ukuba amanye amaqela asebenzayo angangeniswa kule ndawo kwi-benzene ring ukuqhubela phambili ukwakhiwa kwezakhiwo ze-organic molecular, ukubonelela nge-intermediates ebalulekileyo kwi-synthesis yeziyobisi, isayensi yezinto eziphathekayo kunye nezinye. amasimi.
Ngokweendlela zokulungiselela, kuqhelekile ukusebenzisa i-nitrobenzene derivatives ehambelanayo njengesixhobo sokuqala, kwaye ukwazisa iiathom ze-iodine nge-halogenation reaction, kwaye inkqubo yokusabela kufuneka ilawule ngokungqongqo iimeko zokusabela, kubandakanya ubushushu, idosi ye-reagent, ixesha lokuphendula, njl. ., ukuqinisekisa ukukhethwa kunye nokucoceka kwemveliso ekujoliswe kuyo.
Ihlala isetyenziselwa kwintsimi yeekhemikhali ezintle kwizicelo zemizi-mveliso, njengebhloko engundoqo yokwakha ukuhlanganiswa kwee-molecule ezithile ze-bioactive, kwaye inceda kuphando kunye nophuhliso lwamachiza amatsha; Kwintsimi yezinto eziphathekayo, uthatha inxaxheba kwi-synthesis yezixhobo zepolymer ezisebenzayo kwaye uzinike iimpawu ezikhethekileyo ze-optoelectronic, ezibonelela ngesiseko esibalulekileyo sophuhliso lwesayensi kunye nobuchwepheshe bale mihla.
Kufuneka kuqatshelwe ukuba i-compound inetyhefu ethile, kwaye imimiselo engqongqo yokhuseleko lwebhubhoratri yeekhemikhali kufuneka ilandelwe ngexesha lokusebenza kunye nokugcinwa, ukuphepha ukudibanisa nolusu, amehlo, kunye nokuphefumla uthuli lwayo, ukukhusela umonakalo emzimbeni womntu.
