Nhanganyaya
2,3,5-Tribromopyridine is an organic compound ine kemikari formula C5H2Br3N. Iyi inotevera sumo yezvimwe zvayo zvivakwa, mashandisiro, magadzirirwo uye ruzivo rwekuchengetedza:
Zvakasikwa:
-Kuonekwa: 2,3,5-Tribromopyridine haina ruvara kune yakachenuruka yero yakasimba.
-Solubility: Haina kunyungudika mumvura, asi inogona kunyungudika mune organic solvents senge chloroform, dichloromethane, nezvimwe.
-Kunyungudika: 2,3,5-Tribromopyridine ine nzvimbo yakanyunguduka inenge 112-114 ° C.
Shandisa:
- 2,3,5-Tribromopyridine inowanzoshandiswa se reagent uye yepakati mune organic synthesis.
-Iyo inoshandiswa zvakanyanya muminda yekugadzirwa kwezvinodhaka, kugadzirwa kwepesticide uye kugadzira dhayi.
-Kuwedzera, inogona zvakare kushandiswa sechinhu chekutanga chekugadzirwa kwesimbi organic compounds (kusanganisira coordination polymers uye photoelectric zvinhu).
Kugadzirira nzira:
Nzira yekugadzirira ye2,3,5-Tribromopyridine inogona kuwanikwa nematanho anotevera:
Kutanga, pyridine inonyungudutswa mune organic solvent senge dichloromethane kana chloroform.
2. Wedzera bromine kune mhinduro uye kupisa mhinduro.
3. Mushure mekupedzwa kwekuita, chigadzirwa chebrominated chakaitwa hydrolyzed ne dropwise kuwedzera kwemvura.
4. Pakupedzisira, chigadzirwa chacho chakaparadzaniswa uye chinocheneswa nefiltration, crystallization, nezvimwewo.
Zvekuchengetedza
- 2,3,5-Tribromopyridine haizokonzeri nyaya dzekuchengetedza pasi pemamiriro ekushanda.
-Inogona kukonzera kushatirwa paganda, maziso uye turakiti rekufema, saka pfeka zvakakodzera zvekuzvidzivirira nazvo kana uchiishandisa.
-Chengetedza nzira dzakakodzera dzerabhoritari uye matanho ekuchengetedza paunenge uchibata iyi komputa.
-Paunenge uchichengetedza uye uchibata musanganiswa, kutarisirwa kunofanira kutorwa kuti usasangana ne oxidants, yakasimba acids, mabhesi akasimba uye zvimwe zvinhu.
Ndapota cherechedza kuti ruzivo rwuri pamusoro nderwereferensi chete. Paunenge uchishandisa 2,3,5-Tribromopyridine kana chero imwe kemikari, tapota tevera mazano ekushanda kwakachengeteka uye kushandiswa kwakarurama, uye verenga uye uenderane nepepa rekuchengetedza data remakemikari akakodzera.
