Ngozi ndi Chitetezo
| Zizindikiro Zowopsa | R22 - Zowopsa ngati zitamezedwa R37/38 - Zokwiyitsa dongosolo la kupuma ndi khungu. R41 - Kuopsa kwa kuwonongeka kwakukulu kwa maso R36/37/38 - Zokwiyitsa maso, kupuma komanso khungu. R20/21/22 - Zowopsa pokoka mpweya, kukhudzana ndi khungu komanso kumeza. |
| Kufotokozera Zachitetezo | S26 - Mukakhudza maso, yambani nthawi yomweyo ndi madzi ambiri ndikupempha uphungu wachipatala. S39 - Valani chitetezo chamaso / kumaso. S36/37/39 - Valani zovala zodzitchinjiriza zoyenera, magolovesi ndi chitetezo chamaso / kumaso. S36 - Valani zovala zoyenera zodzitetezera. |
2-Fluorobenzonitrile(CAS#394-47-8) Chiyambi
2-Fluorobenzonitrilendi organic pawiri. Ndi madzi achikasu otumbululuka opanda mtundu ndi fungo lamphamvu. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha 2-fluorobenzonitrile:
Katundu:
- 2-Fluorobenzonitrile ndi madzi omwe sagwirizana ndi madzi ndipo amakhala ndi mpweya wochepa kutentha kutentha.
- Imakhala ndi kusungunuka kwabwino ndipo imatha kusungunuka muzosungunulira zambiri monga ethanol, acetone ndi dimethylformamide.
- Imakhala yosasunthika mumlengalenga, koma zowopsa zamankhwala zimatha kuchitika zikatenthedwa kutentha kwambiri kapena zikakumana ndi ma okosijeni amphamvu.
Zogwiritsa:
- Itha kugwiritsidwanso ntchito ngati zopangira zokutira, utoto ndi zonunkhira.
Njira yokonzekera:
- Pali njira ziwiri zazikulu zokonzekera 2-fluorobenzonitrile: cyanide substitution njira ndi fluoride substitution njira.
- Njira yosinthira cyanide imatanthawuza kulowetsa gulu la cyano kukhala mphete ya benzene kenako kuyambitsa maatomu a fluorine m'malo mwa gulu la cyano.
- Fluoride m'malo njira imatanthawuza kugwiritsa ntchito fluoride ngati zopangira, kuchita ndi chlorine, bromine kapena haloform pa mphete ya benzene, m'malo mwa chlorine, bromine kapena haloform ndi fluorine kuti apeze 2-fluorobenzonitrile.
Zambiri Zachitetezo:
- 2-Fluorobenzonitrile ndi poizoni m'thupi la munthu. Chonde pewani kukhudzana mwachindunji ndi khungu, maso ndi kupuma mpweya wake.
- Valani zida zodzitetezera zoyenera monga magolovesi, magalasi oteteza chitetezo komanso zovala zodzitchinjiriza mukamagwira ntchito.
- Posungira, 2-fluorobenzonitrile iyenera kuikidwa mu chidebe chosindikizidwa, kutali ndi moto ndi okosijeni, ndi kusungidwa bwino kuti asatayike ndi kukhudza.
