3-Chloro-4-fluorobenzyl bromide (CAS # 192702-01-5) Okwu mmalite
3-Chloro-4-fluorobenzyl bromide bụ ihe siri ike nke nwere isi ihe dị ka bromobenzene. Ọ nwere ihe na-agbaze nke ihe dị ka 38-39 Celsius C. Na isi ihe na-esi ísì ụtọ nke ihe dịka 210-212 Celsius C. N'ime ụlọ okpomọkụ, ọ fọrọ nke nta ka ọ bụrụ ihe na-adịghị edozi na mmiri, ma soluble na ọtụtụ ihe mgbaze organic.
Jiri:
3-Chloro-4-fluorobenzyl bromide nwere ọtụtụ ngwa ngwa na njikọ organic. Ọ bụ ihe dị mkpa n'etiti maka nkwadebe nke ogige ndị ọzọ na-emepụta ihe, dị ka ọgwụ, agba na pesticides. A na-ejikwa ya na nkwadebe nke ire ere ọkụ, ihe ndị na-ese foto na resin modifiers.
Usoro:
A na-enwetakarị 3-Chloro-4-fluorobenzyl bromide site na imeghachi bromobenzene na tert-butyl magnesium bromide. Nke mbụ, tert-butylmagnesium bromide na-emeghachi omume na bromobenzene na obere okpomọkụ iji nweta tert-butylphenylcarbinol. Mgbe ahụ, site na chlorination na fluorination, otu carbinol nwere ike gbanwee na chlorine na fluorine, na 3-Chloro-4-fluorobenzyl bromide na-etolite. N'ikpeazụ, enwere ike nweta ngwaahịa ezubere iche site na nchacha site na distillation.
Ozi nchekwa:
Jiri 3-Chloro-4-fluorobenzyl bromide na-eleba anya na nsị na mgbakasị ahụ. Ọ nwere ike ịkpasu iwe na sistem iku ume, anụ ahụ na anya. Zere kọntaktị na akpụkpọ ahụ, anya na akụkụ iku ume mgbe ị na-arụ ọrụ. Yiri akụrụngwa nchebe kwesịrị ekwesị, dị ka uwe aka, enyo na ọta ihu. Tụkwasị na nke ahụ, ekwesịrị ịchekwa ya na ebe ikuku na-ekpo ọkụ ma zere kọntaktị na ihe ndị dị ka oxidants siri ike. Ọ bụrụ na iloro ma ọ bụ ikuru ume, chọọ nlekọta ahụike ozugbo. Biko gụọ ntuziaka nchekwa ngwaahịa nke ọma tupu ejiri ya.
