3-Chloro-4-fluorobenzyl bromide (CAS# 192702-01-5) Chiyambi
3-Chloro-4-fluorobenzyl bromide ndi yolimba yokhala ndi fungo lofanana ndi bromobenzene. Ili ndi malo osungunuka a 38-39 ° C. Ndipo malo otentha a 210-212 ° C. Pa kutentha, pafupifupi osasungunuka m'madzi, koma amasungunuka m'madzi ambiri osungunulira.
Gwiritsani ntchito:
3-Chloro-4-fluorobenzyl bromide ili ndi mitundu yambiri yogwiritsira ntchito mu organic synthesis. Ndiwofunika wapakatikati yokonza zina organic mankhwala, monga mankhwala, utoto ndi mankhwala. Amagwiritsidwanso ntchito pokonza zoletsa moto, zinthu zowoneka bwino komanso zosintha utomoni.
Njira:
3-Chloro-4-fluorobenzyl bromide nthawi zambiri imapezeka pochita bromobenzene ndi tert-butyl magnesium bromide. Choyamba, tert-butylmagnesium bromide imayendetsedwa ndi bromobenzene pa kutentha kochepa kuti ipeze tert-butylphenylcarbinol. Kenako, ndi chlorination ndi fluorination, magulu a carbinol amatha kusinthidwa kukhala chlorine ndi fluorine, ndipo bromide 3-Chloro-4-fluorobenzyl imapangidwa. Potsirizira pake, chinthu chandamale chikhoza kupezeka mwa kuyeretsedwa ndi distillation.
Zambiri Zachitetezo:
Gwiritsani ntchito 3-Chloro-4-fluorobenzyl bromide ndi chidwi ndi kawopsedwe ndi kuyabwa. Zingayambitse kuyabwa kwa kupuma, khungu ndi maso. Pewani kukhudzana ndi khungu, maso ndi kupuma thirakiti pa ntchito. Valani zida zodzitetezera zoyenera, monga magolovesi, magalasi ndi zishango zakumaso. Komanso, ziyenera kusungidwa pamalo abwino mpweya wabwino ndi kupewa kukhudzana ndi zinthu monga amphamvu okosijeni. Ngati mwamezedwa kapena kupumitsidwa, pitani kuchipatala mwamsanga. Chonde werengani mosamala malangizo a chitetezo cha mankhwala musanagwiritse ntchito.
