3-Chloro-4-fluorobenzyl bromide （CAS # 192702-01-5) Intangiriro
3-Chloro-4-fluorobenzyl bromide nikintu gikomeye gifite impumuro iranga isa na bromobenzene. Ifite aho ishonga igera kuri 38-39 ° C. N'ahantu ho gutekera nka 210-212 ° C. Ku bushyuhe bwicyumba, usanga bidashobora gushonga mumazi, ariko bigashonga mumashanyarazi menshi.
Koresha:
3-Chloro-4-fluorobenzyl bromide ifite uburyo bwinshi bwo gukoresha muri synthesis. Nibihe byingenzi mugutegura ibindi bintu kama, nkibiyobyabwenge, amarangi nudukoko. Irakoreshwa kandi mugutegura flame retardants, ibikoresho bifotora kandi bihindura resin.
Uburyo:
3-Chloro-4-fluorobenzyl bromide isanzwe iboneka mugukora bromobenzene hamwe na tert-butyl magnesium bromide. Ubwa mbere, tert-butylmagnesium bromide ikorwa na bromobenzene ku bushyuhe buke kugirango ibone tert-butylphenylcarbinol. Noneho, hamwe na chlorine na fluor, amatsinda ya karbinol arashobora guhinduka chlorine na fluor, hanyuma hakorwa 3-Chloro-4-fluorobenzyl bromide. Hanyuma, ibicuruzwa bigenewe bishobora kuboneka mugusukura ukoresheje distillation.
Amakuru yumutekano:
Koresha 3-Chloro-4-fluorobenzyl bromide witondera uburozi no kurakara. Irashobora gutera uburakari sisitemu yubuhumekero, uruhu n'amaso. Irinde guhura n'uruhu, amaso n'inzira z'ubuhumekero mugihe cyo kubaga. Wambare ibikoresho bikingira birinda, nk'uturindantoki, amadarubindi hamwe n'ingabo zo mu maso. Byongeye kandi, igomba kubikwa ahantu hafite umwuka mwiza kandi ikirinda guhura nibintu nka okiside ikomeye. Niba umize cyangwa uhumeka, shaka ubuvuzi bwihuse. Nyamuneka soma amabwiriza yumutekano wibicuruzwa mbere yo gukoresha.
