ʻO 1-Iodo-2-nitrobenzene, nona ka helu CAS o 609-73-4, he mea hoʻohuihui.
Ma ke ʻano, he iodine atom a me kahi hui nitro i hoʻopili ʻia ma kahi kikoʻī (ortho) ma ke apo benzene. Hāʻawi kēia hale kūʻokoʻa iā ia i nā waiwai kemika kūikawā. Ma ke ʻano o nā waiwai kino, ʻike pinepine ʻia ʻo ia me ka melemele māmā a i ka crystalline melemele a i ʻole ka pauka paʻa me kahi ʻano o ka heheʻe a me ka paila ʻana, me kahi helu heheʻe ma waena o 40 - 45 ° C a me kahi paila kiʻekiʻe, kaupalena ʻia e nā kumu. e like me nā mana intermolecular.
Ma ke ʻano o nā waiwai kemika, ma muli o ka ikaika o ka electron-withdraw waiwai o nā pūʻulu nitro a me nā hiʻohiʻona ʻano hana o nā iodine atoms, hiki iā ia ke komo i nā ʻano hana like ʻole synthesis. No ka laʻana, i ka nucleophilic substitution reactions, iodine atoms he mea maʻalahi ka haʻalele, no laila hiki ke hoʻokomo ʻia nā hui hana ʻē aʻe i kēia kūlana ma ke apo benzene e kūkulu hou i nā hale molekala organik paʻakikī, e hāʻawi ana i nā kikowaena koʻikoʻi no ka synthesis lāʻau, ʻepekema waiwai a me nā mea ʻē aʻe. nā mahinaʻai.
Ma ke ʻano o ka hoʻomākaukau ʻana, he mea maʻamau ka hoʻohana ʻana i nā derivatives nitrobenzene e like me ka hoʻomaka ʻana, a hoʻolauna i nā iodine atoms ma o ka halogenation reaction, a ʻo ke kaʻina hana e pono e hoʻomalu pono i nā kūlana hopena, e like me ka mahana, ka reagent dosage, ka manawa manawa, etc. ., e hōʻoia i ka koho a me ka maʻemaʻe o ka huahana i manaʻo ʻia.
Hoʻohana pinepine ʻia ia ma ke kahua o nā kemika maikaʻi i nā noi ʻoihana, ma ke ʻano he kī hale kiʻi no ka synthesis o nā moleke bioactive kikoʻī, a kōkua i ka noiʻi a me ka hoʻomohala ʻana i nā lāʻau lapaʻau hou; Ma ke kahua o nā mea, komo ʻo ia i ka synthesis o nā mea polymer hana a hāʻawi iā lākou i nā waiwai optoelectronic kūikawā, e hāʻawi ana i kahi kumu nui no ka hoʻomohala ʻana i ka ʻepekema a me ka ʻenehana hou.
Pono e hoʻomaopopo ʻia he ʻano mea ʻawaʻawa ka pūhui, a pono e hahai ʻia nā lula palekana kemika i ka wā o ka hana a me ka mālama ʻana, e pale aku i ka pili ʻana me ka ʻili, nā maka, a me ka inhalation o kona lepo, e pale i ka pōʻino i ke kino kanaka.
