| Zizindikiro Zowopsa | R20/21/22 - Zowopsa pokoka mpweya, kukhudzana ndi khungu komanso kumeza. R36/37/38 - Zokwiyitsa maso, kupuma komanso khungu. |
| Kufotokozera Zachitetezo | S26 - Mukakhudza maso, yambani nthawi yomweyo ndi madzi ambiri ndikupempha uphungu wachipatala. S37/39 - Valani magolovesi oyenera komanso chitetezo chamaso / kumaso |
| Kalasi Yowopsa | ZOKWIYA |
Mawu Oyamba
Ndi organic pawiri ndi mankhwala chilinganizo C, H, BrN, O. Zotsatirazi ndi mawu oyamba ena mwa katundu wake, ntchito, njira ndi chitetezo zambiri:
Chilengedwe:
-Mawonekedwe: Opanda utoto mpaka kristalo wachikasu kapena mawonekedwe a ufa.
-Solubility: Ikhoza kusungunuka mu zosungunulira za organic, monga ethanol, dimethyl sulfoxide ndi chloroform, koma osasungunuka m'madzi.
Gwiritsani ntchito:
-Synthetic chemistry: Ndi ligand yomwe imagwiritsidwa ntchito kwambiri, yomwe imatha kupanga ma complexes okhala ndi zitsulo zosinthika ndikugwiritsidwa ntchito ngati chothandizira mu organic synthesis.
-Kupanga mankhwala ophera tizilombo: Atha kugwiritsidwanso ntchito ngati njira yapakati pa mankhwala enaake.
Njira:
Njira yokonzekera ikhoza kuchitidwa ndi njira zotsatirazi:
1. Choyamba, lutidine imasungunuka mu dimethyl sulfoxide.
2. Pa kutentha pang'ono, pang'onopang'ono onjezani asidi wa nitric ndikusunga kutentha kwapansi pa madigiri 0 Celsius.
3. Pang'onopang'ono kuwonjezera bromoethane Dropwise mu dongosolo anachita, kupitiriza kukhala otsika kutentha, ndi kusonkhezera mpaka mapeto a anachita.
4. Pomaliza, zomwe zimasakanikirana zimasefedwa, zotsukidwa, zowumitsidwa ndi zouma kuti zipeze kashiamu.
Zambiri Zachitetezo:
Zitha kubweretsa zoopsa zina mthupi la munthu komanso chilengedwe, chifukwa chake muyenera kusamala pazaumoyo ndi chitetezo mukamagwiritsa ntchito ndikusamalira. Nazi malingaliro ena okhudzana ndi chitetezo:
-Valani zida zodzitetezera zoyenera monga magolovesi, magalasi ndi zovala zodzitetezera mukazigwiritsa ntchito.
-Pewani kutulutsa fumbi lake komanso kukhudzana ndi khungu. Ngati mwakumana mwangozi, nthawi yomweyo tsitsani malo omwe akhudzidwawo ndi madzi ambiri ndikupempha thandizo lachipatala.
- Pewani kutentha ndi moto pamene mukusunga ndi kusamalira, komanso khalani ndi mpweya wabwino.
- Pewani kukhudzana mwachindunji ndi okosijeni, zidulo, ma alkalis ndi zinthu zina kuti mupewe zoopsa.
Chonde dziwani kuti zomwe zaperekedwa pano ndi zongotengera zokha. Mukamagwiritsa ntchito ndikugwiritsa ntchito mankhwala, onetsetsani kuti mwatchula zolemba zoyenera komanso malamulo oyendetsera chitetezo, ndikutsatira malangizo a akatswiri.
