Intshayelelo

I-Nitrobenzyl bromide yi-organic compound, kwaye oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi olukhuselekileyo lwe-nitrobenzyl bromide:

 

Umgangatho:

I-Nitrobenzyl bromide yinto eqinileyo eneekristale ezimhlophe kwiqondo lobushushu begumbi. Inevumba elirhabaxa kwaye ineqondo eliphezulu lokunyibilika kunye nelokubila. Ikhompawundi ayinyibiliki emanzini kwaye kulula ukunyibilika kwizinyibilikisi eziphilayo ezifana ne-ethanol kunye ne-ether.

 

Sebenzisa:

I-Nitrobenzyl bromide ineendlela ezahlukeneyo zokusetyenziswa kwishishini lemichiza. Ingasetyenziswa njengento ekrwada ukwenzela reactions organic synthesis, kwaye bathathe inxaxheba endaweni reaction of benzene ring ukuvelisa ezahlukeneyo iikhompawundi eziphilayo ezahlukeneyo.

 

Indlela:

Indlela yokulungisa i-nitrobenzyl bromide idla ngokubandakanya ukutshintshwa kweringi yebenzene. Indlela eqhelekileyo yokulungiswa kukusebenzisa i-reaction ye-sodium bromide (NaBr) kunye ne-nitric acid (HNO3) ukuguqula i-bromine kwi-bromobenzene, ethi emva koko iphendule nge-nitrooxides (njenge-nitrosobenzene okanye i-nitrosotoluene) ukuvelisa i-nitrobenzyl bromide.

 

Ulwazi ngoKhuseleko:

I-Nitrobenzyl bromide yityhefu ekhompawundi ecaphukisayo kwaye edlekayo. Ukuqhagamshelana nolusu kunye namehlo kunokubangela ukucaphuka kunye neentlungu, kwaye ukuphefumla okanye ukugqithiswa kwamanani amaninzi kunokubangela umonakalo kwiinkqubo zokuphefumula kunye nokugaya. Iiglavu ezikhuselayo, iiglasi kunye nemaski kufuneka zinxitywe xa usebenzisa i-nitrobenzyl bromide, kwaye umsebenzi kufuneka wenziwe kwindawo engenamoya. Ukongeza, kufuneka igcinwe kude nemithombo yokutshisa kunye ne-oxidizers ukukhusela umlilo kunye nokuqhuma. Iiprothokholi ezifanelekileyo zaselabhoratri kunye nemilinganiselo yokhuseleko kufuneka ilandelwe xa kusingathwa le khompawundi.

  • Okulandelayo:
    • Bhala umyalezo wakho apha kwaye uwuthumele kuthi
