Nhanganyaya

O-dibromobenzene musanganiswa weorganic. Izvi zvinotevera sumo kune zvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza o-dibromobenzene:

 

Hunhu:

-Kuonekwa: O-dibromobenzene ikristaro isina ruvara kana chena yakasimba.

- Solubility: O-dibromobenzene inonyungudika mune mamwe organic solvents, senge benzene uye doro.

 

Shandisa:

- Organic zvigadzirwa zvemagetsi: o-dibromobenzene inogona kushandiswa mukugadzirira organic optoelectronic zvinhu, liquid crystal kuratidza, nezvimwe.

 

Nzira:

Iyo huru yekugadzirira nzira ye-o-dibromobenzene inowanikwa nekutsiva reaction yebromobenzene. Nzira inowanzoshandiswa ndeyekunyungudutsa benzene mumusanganiswa weferrous bromide uye dimethyl sulfoxide uye kuita pane tembiricha yakakodzera kuti uwane o-dibromobenzene.

 

Zvekuchengetedza

- O-dibromobenzene ine imwe toxicity uye chaiyo toxicity data inoda kuongororwa pane imwe nyaya-ne-kesi.

- Pfeka magurovhosi uye magirazi paunenge uchishandisa o-dibromobenzene kudzivirira ganda rako nemaziso.

- Dzivisa kufema o-dibromobenzene mhute kana kumwaya pameso nepaganda.

- Dzivisa kusangana pakati pe-o-dibromobenzene uye yakasimba oxidants, kupisa uye kupisa kwakanyanya.

- Panguva yekushandiswa uye kuchengetedza, kutarisisa kunofanirwa kubhadharwa kune moto uye kuputika matanho ekudzivirira kuchengetedza mhepo yakanaka.

- Pakurasa marara, tichatevedzera mitemo yenzvimbo yezvakatipoteredza uye mirairo uye kutora matanho akakodzera ekurasa tsvina.
