Okwu mmalite
Acid, nke a na-akpọkwa acid, bụ ngwakọta organic. Nke a bụ nkọwa nke ọdịdị ya, ojiji ya, nkwadebe na ozi nchekwa ya:
Ọdịdị:
- Ọdịdị: acid bụ ọcha crystalline ntụ ntụ.
- Usoro ihe omimi: C6H4BrNO2.
-Arọ molekụla: 206.008g/mol.
- Ebe mgbaze: ihe dịka 132-136 Celsius.
-Stable na ụlọ okpomọkụ na soluble na ụfọdụ organic solvents.
Jiri:
-Acid a na-ejikarị dị ka akụrụngwa ma ọ bụ n'etiti na organic njikọ.
- Enwere ike iji ya mee ka usoro nke ogige heterocyclic nwere nitrogen, dị ka pyridine na pyridine.
-A nwekwara ike iji ya kwado ogige ndị na-arụ ọrụ ndụ, dị ka ọgwụ pesticides, ọgwụ na ihe e ji esiji ákwà.
Ụzọ nkwadebe:
-¾ acid na-akwadokarị site na mmeghachi omume nke bromo-nicotinic acid. Usoro njikọ a na-ahụkarị bụ mmeghachi omume nicotinic acid na bromoethanol n'okpuru ọnọdụ alkaline, na-esote acidification iji nweta ngwaahịa ahụ.
Ozi nchekwa:
-Acid kwesịrị ịgbaso usoro nchekwa ụlọ nyocha izugbe n'oge eji.
-Ọ nwere ike ịkpasu iwe na anya, akpụkpọ ahụ na akụkụ iku ume, ya mere a ga-ezere kọntaktị ozugbo n'oge ọrụ.
-na nchekwa na ojiji kwesịrị ịṅa ntị iji zere kọntaktị na oxidants, acid siri ike na ihe ndị ọzọ, iji zere ihe ndị dị ize ndụ ma ọ bụ mmeghachi omume.
-Ọ bụrụ na ọ dị mkpa, rụọ ọrụ na mpaghara ikuku nke ọma, na-eyi uwe mkpuchi nchebe, iko nchebe na ihe mkpuchi nchebe. Ọ bụrụ na ikuru ume ma ọ bụ kpughee, chọọ ndụmọdụ ahụike.
