2-Chloro-5-fluorobenzaldehyde (CAS# 84194-30-9)
Ngozi ndi Chitetezo
| Zizindikiro Zowopsa | R22 - Zowopsa ngati zitamezedwa R37/38 - Zokwiyitsa dongosolo la kupuma ndi khungu. R41 - Kuopsa kwa kuwonongeka kwakukulu kwa maso |
| Kufotokozera Zachitetezo | S26 - Mukakhudza maso, yambani nthawi yomweyo ndi madzi ambiri ndikupempha uphungu wachipatala. S39 - Valani chitetezo chamaso / kumaso. |
| Kalasi Yowopsa | ZOKWIYA |
Mawu Oyamba
-Maonekedwe: Makristalo oyera kapena olimba achikasu.
- Malo osungunuka: pafupifupi 40-42 ℃.
- Malo otentha: pafupifupi 163-165 ℃.
- Kachulukidwe: pafupifupi 1.435g/cm³.
-Kusungunuka: Imasungunuka mu zosungunulira zina wamba, monga ethanol, chloroform ndi dichloromethane.
Gwiritsani ntchito:
Amagwiritsidwa ntchito kwambiri popanga ma organic synthesis. Itha kugwiritsidwa ntchito ngati utoto wapakatikati wa utoto wa fulorosenti, ngati zopangira m'munda wamankhwala, komanso m'munda waulimi pokonzekera mankhwala ophera tizilombo.
Njira Yokonzekera:
itha kukonzedwa ndi chlorination, fluorinated benzaldehyde njira. Njira yeniyeni yokonzekera ndi iyi:
1. Pazifukwa zoyenera, hydrofluoric acid imawonjezeredwa ku benzaldehyde kuti ilole kuti ikhale ndi fluorination reaction.
2. Pambuyo pa zomwe zimachitika, hydrogen chloride imawonjezeredwa ku chlorine mankhwala opangidwa ndi fluorinated.
3. tsatirani njira zoyenera zoyeretsera kuti mupeze phosphonium yoyera.
Zambiri Zachitetezo:
- ndi zinthu zoipa, zingayambitse mkwiyo ndi kuwonongeka kwa thupi la munthu. Valani magolovesi oteteza, magalasi ndi zida zodzitetezera ngati pakufunika kutero.
-Pewani kutulutsa fumbi kapena mpweya wake, komanso pewani kukhudza khungu ndi maso.
-Panthawi yosungira ndikugwiritsa ntchito, njira zotetezera mankhwala ziyenera kuwonedwa, ndipo mpweya wabwino uyenera kusungidwa.
-Kuwonekera mwangozi kapena kumeza, funsani kuchipatala mwamsanga ndikupereka deta yoyenera yotetezera.
