3-Nitro-5-bromobenzoic acid (3-Bromo-5-nitrobenzoic acid) bụ ngwakọta organic na usoro kemịkalụ C7H4BrNO4. Nke a bụ nkọwa nke njirimara, ojiji, nkwadebe na ozi nchekwa nke ogige ahụ:
Ọdịdị:
- Ọdịdị: 3-Nitro-5-bromobenzoic acid bụ ìhè odo siri ike.
- Ebe mgbaze: ihe dịka 220-225 ° C.
-Solubility: Solubility dị ala na mmiri, ma soluble na ihe mgbaze dị ka ethanol, chloroform na dichloromethane.
-acid na alkaline: bụ acid na-adịghị ike.
Jiri:
A na-ejikarị -3-nitro-5-bromobenzoic acid mee ihe dị ka onye na-ahụ maka ihe ndị na-emepụta ihe ma na-eji ya eme ihe na nkwadebe nke ogige ndị ọzọ.
-A nwekwara ike iji ya na-akwadebe ogige dị ka ọgwụ, ihe eji esiji ákwà na mkpuchi.
Ụzọ nkwadebe:
Enwere ike mezue nkwadebe nke 3-nitro-5-bromobenzoic acid site na usoro ndị a:
1. 3-nitrobenzoic acid nwetara site na mmeghachi omume nke benzoic acid na nitrous acid.
2. Na ọnụnọ nke bromide ferrous, 3-nitrobenzoic acid na-emeghachi omume na sodium bromide iji nweta 3-nitro-5-bromobenzoic acid.
Ozi nchekwa:
3-Nitro-5-bromobenzoic acid na-adịkarị mma na ojiji na nchekwa kwesịrị ekwesị. Agbanyeghị, ihe ndị a ka kwesịrị iburu n'uche:
- Zere kọntaktị akpụkpọ ahụ, iku ume na iri nri mgbe ị na-arụ ọrụ.
-Yiri akụrụngwa nchebe kwesịrị ekwesị dịka uwe aka, ugogbe anya na ọta ihu mgbe ejiri ya.
-Ọ bụrụ na ị bata na kọntaktị ahụ, kpochaa ya ozugbo na ọtụtụ mmiri ma chọọ nlekọta ahụike.
-Ekwesịrị ịchekwa ya pụọ na ọkụ na oxidant, n'ebe dị jụụ, nke kpọrọ nkụ.
Mara: Ozi dị n'elu bụ naanị maka ntụnye aka. Biko soro ụkpụrụ nchekwa dị mkpa mgbe ị na-arụ ọrụ na ụlọ nyocha, ma lelee mpempe data nchekwa nke ogige ahụ akọwapụtara ma ọ dị mkpa.
