Nhanganyaya
is an organic compound, chemical formula for C7H3BrF4, kutaridzika kwayo haina ruvara kana light yellow fluid. Inotevera rondedzero yehunhu hwayo, kushandiswa, kugadzirira uye ruzivo rwekuchengetedza:
Zvakasikwa:
-Density: approx. 1.894g/cm³
-Kunyungudika: inenge -23°C
-Kubikira nzvimbo: inenge 166-168°C
-Solubility: Inonyungudika mune zvakajairika organic solvents, senge ethanol, dimethylformamide uye dichloromethane.
Shandisa:
Inonyanya kushandiswa mumunda we organic synthesis sechinhu chakasvibirira chekugadzirwa kwemhando dzakasiyana dzemishonga uye yepakati. Inowanzoshandiswa mukuita fluorination uye alkylation reactions. Mukuwedzera, inogonawo kushandiswa kugadzira mishonga yezvipembenene, photoelectric zvinhu uye mamwe organic compounds.
Kugadzirira nzira:
Kune dzakawanda nzira dzekugadzira phosphor, uye nzira yakajairika inowanikwa nekuita kwe4-bromo-fluorobenzene uye fluorine gasi pamberi pechigadziriso. Iyo chaiyo yekugadzirira nzira inoda mamwe ma laboratori maitiro uye mamiriro.
Zvekuchengetedza
-kazhinji yakachengeteka pasi pemamiriro ekushandiswa akajairwa. Zvisinei, chero chinhu chemakemikari chinofanira kushandiswa nemazvo uye kutevera nzira dzakachengeteka dzekushanda.
-Pfeka midziyo yekudzivirira yakakodzera senge magirovhosi ekudzivirira, magogi uye masks ekudzivirira kana uchishandiswa.
-Dzivisa kufema mhute dzayo kana kubata neganda nemaziso.
-Panguva yekuchengetedza uye kubata, dzivisa kusangana neakasimba oxidants uye yakakwirira tembiricha mamiriro.
-Muchiitiko chekusangana netsaona kana kushandiswa zvisina kunaka, tsvaga kurapwa nekukurumidza.
