Mawu Oyamba
2-Chloro-4-fluorobenzoic acid ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chitetezo cha 2-chloro-4-fluorobenzoic acid:
Ubwino:
- Maonekedwe: 2-Chloro-4-fluorobenzoic asidi ndi woyera crystalline olimba.
- Kusungunuka: Imakhala ndi kusungunuka kochepa m'madzi, koma imasungunuka bwino mu zosungunulira za organic (mwachitsanzo, ethanol, acetone).
- Kukhazikika: Ndi chinthu chokhazikika, koma kukhudzana ndi ma okosijeni amphamvu ndi ma acid kuyenera kupewedwa.
Gwiritsani ntchito:
- Chemical intermediates: 2-chloro-4-fluorobenzoic asidi angagwiritsidwe ntchito ngati intermediates mankhwala mu kaphatikizidwe organic.
- Surfactant: Itha kugwiritsidwa ntchito ngati zopangira zopangira ma surfactants ndipo imakhala ndi zochitika zabwino zapamtunda komanso zobalalika.
- Zipangizo za Photosensitive: 2-chloro-4-fluorobenzoic acid zitha kugwiritsidwa ntchito popanga zinthu zowoneka bwino, monga zomatira zowala.
Njira:
2-Chloro-4-fluorobenzoic acid imatha kupezeka ndi fluorochloro-substitution reaction ya p-dichlorobenzoic acid kapena difluorobenzoic acid. Njira zenizeni zokonzekera zingaphatikizepo fluorochloro-substitution, fluorination kapena zina zoyenera zolowa m'malo.
Zambiri Zachitetezo:
- Kawopsedwe: 2-chloro-4-fluorobenzoic acid ndi gulu la organofluorine, lomwe lili ndi poizoni wocheperako kuposa mankhwala onse a organofluorine. Komabe, samalani kuti musapume mpweya kapena kukhudzana.
- Kupsa mtima: Kungayambitse kuyabwa m'maso, khungu ndi kupuma ndipo ziyenera kutsukidwa mukangokhudzana.
- Zozimitsa moto: Pamoto, kuzimitsa kuyenera kuchitidwa ndi chozimitsa choyenera monga carbon dioxide, thovu kapena ufa wouma, kupewa kugwiritsa ntchito madzi kuzimitsa moto chifukwa ali ndi kusungunuka kochepa m'madzi.
- Kusungirako: 2-Chloro-4-fluorobenzoic acid iyenera kusungidwa pamalo owuma, odutsa mpweya wabwino, kutali ndi moto ndi zowonjezera zowonjezera.
