Nhanganyaya
Iyo organic compound ine kemikari formula C7H3BrF4. Imvura isina ruvara kune yakachenuruka yero uye ine hwema hwakakosha patembiricha.
Zvakasikwa:
1. nzvimbo yakanyungudika:-33 ℃
2. Poindi yekubikira: 147-149 ℃
3. kuwanda: 1.889g/cm³
4. Solubility: Soluble in organic solvents yakadai se ether, ethanol uye dichloromethane, isingasviki mumvura.
Shandisa:
Inonyanya kushandiswa seyepakati mune organic synthesis. Inowanzoshandiswa mukugadzirwa kwezvinodhaka, kemikari catalysis uye organic zvinhu, zvakadai sebenzopyrazolones, cyclic macrocyclization, organic photoelectric materials synthesis, nezvimwewo.
Kugadzirira nzira:
Iyo nzira yekugadzirira calcium inonyanya kuburikidza nekuita kwebromobenzene uye trifluorotoluene pasi pemamiriro akakodzera. Kazhinji, bromobenzene inopindirana ne trifluorotoluene pamberi pehupfu hwemhangura kana cuprous pasi pekupisa kuti igadzire fluorotoluene.
Zvekuchengetedza
Inotsamwisa uye inofanira kudzivisa kusangana zvakananga neganda nemaziso. Zvishandiso zvekuzvidzivirira nazvo zvakaita semagirovhosi ekudzivirira, magirazi uye zvipfeko zvekudzivirira zvinofanirwa kupfekwa panguva yekushandiswa nekubata. Dzivisa kufemesa mhute dzayo uye ita chokwadi chekushanda munzvimbo ine mhepo inofefetera. Mukuwedzera, inofanira kuchengetwa mumudziyo wakavharwa, kure nekupisa uye moto. Mukushandisa kana kuraswa, ndapota tevera maitiro akakodzera ekuchengetedza. Kana pakadonhera, panofanira kutorwa matanho ekuchenesa nekurasa akakodzera. Kana zvichidiwa, nyanzvi inofanira kubvunzurudzwa.
