Zvakasikwa:
-Kuonekwa: 3-Nitro-5-bromobenzoic asidhi chiedza yero yakasimba.
-Kunyungudika: inenge 220-225°C.
-Solubility: Yakaderera solubility mumvura, asi inonyungudika muzvinonyungudutsa senge ethanol, chloroform uye dichloromethane.
-asidhi uye alkaline: iasidhi isina simba.
Shandisa:
-3-nitro-5-bromobenzoic acid inowanzoshandiswa sepakati mune organic synthesis uye inoshandiswa mukugadzirira kwemamwe makemikari.
-Inogonawo kushandiswa kugadzira makomba akadai semishonga, dhayi uye machira.
Kugadzirira nzira:
Kugadzirira kwe3-nitro-5-bromobenzoic acid kunogona kupedzwa nematanho anotevera:
1. 3-nitrobenzoic acid yakawanikwa nekuita kwe benzoic acid uye nitrous acid.
2. Pamberi pe ferrous bromide, 3-nitrobenzoic acid inobatwa ne sodium bromide kuti iwane 3-nitro-5-bromobenzoic acid.
Zvekuchengetedza
3-Nitro-5-bromobenzoic acid inowanzochengeteka mukushandiswa kwakakodzera uye kuchengetedza. Nekudaro, zvinotevera zvinofanirwa kucherechedzwa:
-Dzivisa kubata kweganda, inhalation uye kupinza panguva yekushanda.
-Pfeka midziyo yekudzivirira yakakodzera senge magirovhosi, magirazi, nenhoo yekumeso kana yashandiswa.
-Kana ukasangana nekomboni, sukurudza nekukurumidza nemvura yakawanda uye tsvaga kurapwa.
-inofanira kuchengetwa kure nemoto uye oxidant, munzvimbo inotonhorera, yakaoma.
Cherechedza: Ruzivo rwuri pamusoro nderwereferensi chete. Ndokumbira uteedzere iyo yakakodzera mitemo yekuchengetedza paunenge uchishanda murabhoritari, uye tarisa pepa rekuchengetedza data reiyo komboni kana zvichidikanwa.
