3-Chloro-4-fluorobenzyl bromide (CAS# 192702-01-5) Selelekela
3-Chloro-4-fluorobenzyl bromide ke ntho e tiileng e nang le monko o tšoanang le oa bromobenzene. E na le ntlha ea ho qhibiliha hoo e ka bang 38-39 ° C. Le ntlha e belang e ka bang 210-212 ° C. Ka mocheso oa kamore, e batla e sa qhibilihe ka metsing, empa e qhibiliha ka bongata ba li-solvents.
Sebelisa:
3-Chloro-4-fluorobenzyl bromide e na le mefuta e mengata ea lisebelisoa ho organic synthesis. Ke ea bohlokoa lipakeng bakeng sa ho lokisa metsoako e meng ea manyolo, joalo ka lithethefatsi, dae le chefo e bolaeang likokoanyana. E boetse e sebelisoa ho lokiseng li-retardants tsa lelakabe, lisebelisoa tsa ho nka lifoto le li-resin modifiers.
Mokhoa:
3-Chloro-4-fluorobenzyl bromide hangata e fumanoa ka ho sebelisa bromobenzene ka tert-butyl magnesium bromide. Taba ea pele, tert-butylmagnesium bromide e sebetsa ka bromobenzene ka mocheso o tlase ho fumana tert-butylphenylcarbinol. Joale, ka chlorination le fluorination, lihlopha tsa carbinol li ka fetoloa chlorine le fluorine, 'me 3-Chloro-4-fluorobenzyl bromide e thehoa. Qetellong, sehlahisoa se lebisitsoeng se ka fumanoa ka ho hloekisoa ka distillation.
Lintlha tsa Tšireletseho:
Sebelisa 3-Chloro-4-fluorobenzyl bromide ka tlhokomelo ea chefo le ho teneha. E ka baka ho teneha ho tsamaiso ea phefumoloho, letlalo le mahlo. Qoba ho kopana le letlalo, mahlo le phefumoloho nakong ea ts'ebetso. Apara lisebelisoa tse loketseng tsa ho itšireletsa, tse kang liatlana, likhalase le lithebe tsa sefahleho. Ho phaella moo, e lokela ho bolokoa sebakeng se nang le moea o motle 'me u qobe ho kopana le lintho tse kang li-oxidants tse matla. Haeba u koetsoe kapa u hema, batla thuso ea bongaka hang-hang. Ka kopo bala litaelo tsa polokeho ea sehlahisoa ka hloko pele u sebelisoa.
