Mawu Oyamba
Ndi organic pawiri ndi mankhwala chilinganizo C6H5BrN2O2. Zotsatirazi ndizofotokozera zina mwazinthu zake, ntchito, njira ndi chidziwitso chachitetezo:
Chilengedwe:
-Maonekedwe: Mwala wonyezimira woyera.
- Malo osungunuka: pafupifupi 130-132 digiri Celsius.
-Kuwira: pafupifupi 267-268 digiri Celsius.
-Kusungunuka: Kusungunuka mu zosungunulira zina za organic.
Gwiritsani ntchito:
-angagwiritsidwe ntchito organic kaphatikizidwe anachita, monga cyanidation anachita, nitration anachita.
-Nthawi zambiri amagwiritsidwa ntchito ngati gawo lapakati lofunikira pakuphatikizika kwazinthu zina zachilengedwe.
- Pankhani ya kafukufuku wa mankhwala, amagwiritsidwanso ntchito pokonzekera mankhwala ena oletsa tizilombo toyambitsa matenda.
Njira: Kaphatikizidwe ka
- nthawi zambiri amapezeka ndi nitration wa pyridine. Pyridine imayamba kuchitidwa ndi asidi wa nitric ndikuyika sulfuric acid, kenako amathandizidwa ndi hydrogen bromide solution kuti apeze zomwe akufuna.
Zambiri Zachitetezo:
-ndi organic pawiri ndi mlingo winawake wa zoopsa. Valani magolovesi oteteza ndi magalasi pochita opaleshoni kuti musakhudze khungu ndi maso.
-Pewani kutulutsa fumbi kapena gasi ndikugwirira ntchito pamalo opumira bwino a labotale.
-Pawiriyi imatha kukhala ndi teratogenic, carcinogenic kapena zoyipa zina kwa anthu, chifukwa chake njira zotetezera ziyenera kutsatiridwa mosamalitsa. Mu kukhudzana kapena inhalation pambuyo bongo, ayenera yake mankhwala.
