Okwu mmalite
5-fluoro-2-nitrobenzoic acid (5-fluoro-2-nitrobenzoic acid) bụ ngwakọta organic na usoro kemịkalụ C7H4FNO4. Nke a bụ nkọwa nke ọdịdị ya, ojiji ya, nkwadebe na ozi nchekwa ya:
Ọdịdị:
- Ọdịdị: 5-fluoro-2-nitrobenzoic acid bụ ọcha ma ọ bụ na-acha ọcha crystalline ntụ ntụ.
- Ebe mgbaze: Ihe dịka 172 ° C.
-Solubility: ntakịrị soluble na mmiri, soluble na ụfọdụ organic solvents dị ka alcohols na esters.
Jiri:
- Ngwakọta kemịkalụ: 5-fluoro-2-nitrobenzoic acid bụ ihe a na-ejikarị eme ihe n'etiti etiti, nke enwere ike iji mejupụta ogige ndị ọzọ dị ndụ, dị ka ọgwụ, pesticides na akwa.
-Ebumnuche nyocha sayensị: N'ihi usoro ya nwere fluorine na otu nitro, 5-fluoro-2-nitrobenzoic acid nwere akụrụngwa kemịkalụ pụrụ iche ma enwere ike iji ya mee nyocha na nyocha ụlọ nyocha.
Usoro:
Usoro nkwadebe nke 5-fluoro-2-nitrobenzoic acid na-enwetakarị site na mmeghachi omume fluorination nke 2-nitrobenzoic acid.
1. Nke mbụ, 2-nitrobenzoic acid na-emeghachi omume na onye na-ahụ maka fluorinating (dị ka hydrogen fluoride ma ọ bụ sodium fluoride).
2. Mgbe mmeghachi omume gasịrị, a nwetara ngwaahịa 5-fluoro-2-nitrobenzoic acid.
Ekwesiri iburu n'uche na n'oge usoro nkwadebe, a ghaghị iji ọnọdụ ọrụ nnwale kwesịrị ekwesị na usoro nchekwa iji hụ na nchekwa nke nnwale ahụ.
Ozi nchekwa:
A na-ewere 5-fluoro-2-nitrobenzoic acid dị ka ogige dị nchebe n'okpuru ọnọdụ izugbe, mana ọ ka kwesịrị iji nlezianya mee ya ma soro usoro nnwale kwesịrị ekwesị.
-Na kọntaktị na ngwakọta a, a ga-ezere kọntaktị anụ ahụ kpọmkwem na iku ume nke ájá ya.
-N'ime usoro iji na nchekwa, biko chebe akụrụngwa ụlọ nyocha nke ọma, ma soro ntuziaka nchekwa dị mkpa.
-Ọ bụrụ na ihe mberede ma ọ bụ ihe a na-enyo enyo na-egbu egbu, chọọ nlekọta ahụike ozugbo wee weta mpempe akwụkwọ nchekwa nchekwa nke ogige ahụ.
