Selelekela
2,5-Difluorobenzyl bromide. Se latelang ke selelekela sa sebopeho sa eona, tšebeliso, mokhoa oa ho lokisa le tlhaiso-leseling ea polokeho:
Boleng:
Ponahalo: 2,5-benzyl difluorobromide ke mokelikeli o se nang 'mala kapa o mosehla hanyenyane.
Boima: 1.74-1.76 g/cm³.
Solubility: Ho qhibiliha ka har'a lihlapolli tsa tlhaho tse kang joala, li-ether le lihlapolli tse se nang polar.
Sebelisa:
2,5-difluorobenzyl bromide e sebelisoa haholo-holo e le motsoako o bohareng le o tala ka har'a motsoako oa manyolo.
Ho organic synthesis, hangata e sebelisoa bakeng sa fluorination ea olefin le fluorination e khethiloeng ea metsoako e nkhang hamonate.
Mokhoa:
Tokisetso ea 2,5-difluorobenzyl bromide e ka etsoa ka mehato e latelang:
Ntlha ea pele, 2,5-dibromobenzyl le trifluoroacetic acid li sebetsa 'me li kenngoa hape ka khase ea condensate kapa metsi ho lokisetsa tharollo ea 2,5-difluorobenzylbromide.
Sehlahisoa se hloekileng sa 2,5-difluorobenzyl bromide sea belisoa, se tlhotloa, ebe se omisoa.
Lintlha tsa Tšireletseho:
2,5-difluorobenzyl bromide e na le chefo e itseng, 'me mehato ea tšireletso e lokela ho nkoa ha e sebelisoa, ho qoba ho kopana le letlalo, mahlo le tsela ea ho hema.
Nakong ea ts'ebeliso le ho itokisa, ho lokela ho fanoa ka lisebelisoa tse nepahetseng tsa ts'ireletso tse kang liatlana tsa laboratori, likhalase le limaske tse sireletsang.
E lokela ho sebetsoa sebakeng se nang le moea o motle 'me u qobe ho kopana le mehloli ea ho khantša le li-oxidants.
Ha e bolokoa, 2,5-difluorobenzyl bromide e lokela ho bolokoa sebakeng se phodileng, se omeletseng le se nang le moea o pholileng, hole le mollo le lintho tse tukang.
Ka kopo latela mekhoa e nepahetseng ea laboratori le litataiso tsa ho sebetsana ka mokhoa o sireletsehileng ha u sebelisa le ho tšoara 2,5-difluorobenzyl bromide.
