Gwiritsani ntchito:
1-bromo-2,3,4-trifluorobenzene imagwiritsidwa ntchito ngati gawo lapakati pakupanga organic. Imakhala ndi ntchito zosiyanasiyana pakuphatikizika kwamankhwala, kaphatikizidwe ka mankhwala ophera tizilombo, kaphatikizidwe ka utoto ndi zina. Itha kugwiritsidwanso ntchito ngati chigawo cha photoresist, chowonjezera cha zinthu zamagetsi, kapena zina zotero.
Njira:
Kukonzekera kwa 1-bromo-2,3,4-trifluorobenzene kungathe kuchitidwa ndi njira zosiyanasiyana. Njira yodziwika bwino ndikuyankhira bromobenzene ndi hydrogen fluoride kupereka 1-bromo-2,3,4-trifluorobenzene. Itha kukonzedwanso pochita bromobenzene ndi antimony trifluoride.
Zambiri Zachitetezo:
1-bromo-2,3,4-trifluorobenzene ndi yovulaza thupi la munthu ndi chilengedwe. Ndi madzi oyaka omwe amatulutsa mpweya wapoizoni akayatsidwa ndi malawi otseguka kapena kutentha kwambiri. Kukhudzana ndi khungu ndi maso kungayambitse mkwiyo ndi kutentha kwa mankhwala. Chifukwa chake, mukamagwiritsa ntchito 1-bromo-2,3,4-trifluorobenzene, muyenera kuvala zida zoyenera zodzitetezera ndikuwonetsetsa kuti ntchitoyi ikuchitika pamalo abwino mpweya wabwino.
