Isingeniso

I-Nitrobenzyl bromide iyinhlanganisela yezinto eziphilayo, futhi okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-nitrobenzyl bromide:

 

Ikhwalithi:

I-Nitrobenzyl bromide iqinile enamakristalu amhlophe ekamelweni lokushisa. Inephunga elimnandi futhi inezinga eliphezulu lokuncibilika kanye nokubila. Inhlanganisela ayincibiliki emanzini futhi incibilika kalula kuzincibilikisi zemvelo ezifana ne-ethanol ne-ether.

 

Sebenzisa:

I-Nitrobenzyl bromide inokusetshenziswa okuhlukahlukene embonini yamakhemikhali. Ingasetshenziswa njengezinto ezingavuthiwe zokusabela kwe-organic synthesis, futhi ingabamba iqhaza ekuphenduleni esikhundleni kweringi ye-benzene ukuze kukhiqizwe izinhlanganisela ezihlukahlukene zezinto eziphilayo.

 

Indlela:

Indlela yokulungiselela ye-nitrobenzyl bromide ivamise ukubandakanya ukusabela kokufakwa esikhundleni kweringi ye-benzene. Indlela evamile yokulungiselela ukusebenzisa ukusabela kwe-sodium bromide (NaBr) kanye ne-nitric acid (HNO3) ukuguqula i-bromine ibe i-bromobenzene, ebese isabela nge-nitrooxides (njenge-nitrosobenzene noma i-nitrosotoluene) ukukhiqiza i-nitrobenzyl bromide.

 

Ulwazi Lokuphepha:

I-Nitrobenzyl bromide iyinhlanganisela enobuthi ecasulayo futhi ebolayo. Ukuthinta isikhumba namehlo kungabangela ukucasuka nobuhlungu, futhi ukuhogela umoya noma ukumunca amanani amakhulu kungabangela ukulimala ohlelweni lokuphefumula nolokugaya ukudla. Amagilavu ​​okuzivikela, izibuko kanye nemaski kufanele kugqokwe uma usebenzisa i-nitrobenzyl bromide, futhi ukuhlinza kufanele kwenziwe endaweni enomoya omuhle. Ngaphezu kwalokho, kufanele igcinwe kude nemithombo yokuthungela kanye nama-oxidizer ukuvimbela umlilo nokuqhuma. Izivumelwano ezifanele zaselabhorethri kanye nezinyathelo zokuphepha kufanele zilandelwe lapho kusingathwa lesi sithako.
