Selelekela
5-fluoro-2-nitrobenzoic acid(5-fluoro-2-nitrobenzoic acid) ke motsoako oa organic o nang le foromo ea lik'hemik'hale C7H4FNO4. E latelang ke tlhaloso ea sebopeho sa eona, ts'ebeliso, tokiso le tlhaiso-leseling ea polokeho:
Tlhaho:
-Ponahalo: 5-fluoro-2-nitrobenzoic acid ke phofo e tšoeu kapa e tšoeu ea kristale.
- Sebaka sa ho qhibiliha: Hoo e ka bang 172°C.
-Solubility: E qhibiliha hanyenyane ka metsing, e qhibiliha ka har'a metsoako e meng ea tlhaho e kang joala le ester.
Sebelisa:
-Chemical synthesis: 5-fluoro-2-nitrobenzoic acid ke hangata e sebelisoang organic synthesis intermediate, e ka sebelisoang ho kopanya metsoako e meng ea manyolo, joalo ka lithethefatsi, chefo e bolaeang likokoanyana le dae.
-Merero ea lipatlisiso tsa mahlale: Ka lebaka la sebopeho sa eona se nang le lihlopha tsa fluorine le nitro, 5-fluoro-2-nitrobenzoic acid e na le lisebelisoa tse khethehileng tsa lik'hemik'hale 'me e ka sebelisoa bakeng sa lipatlisiso le liteko tsa laboratori.
Mokhoa:
Mokhoa oa ho lokisa oa 5-fluoro-2-nitrobenzoic acid hangata o fumanoa ka karabelo ea fluorination ea 2-nitrobenzoic acid.
1. Ntlha ea pele, 2-nitrobenzoic acid e sebetsanoa le moemeli oa fluorinating (joaloka hydrogen fluoride kapa sodium fluoride).
2. Ka mor'a karabelo, sehlahisoa sa 5-fluoro-2-nitrobenzoic acid se ile sa fumanoa.
Hoa lokela ho hlokomeloa hore nakong ea ts'ebetso ea ho itokisa, maemo a nepahetseng a ts'ebetso ea liteko le mehato ea tšireletso e tlameha ho sebelisoa ho netefatsa polokeho ea teko.
Lintlha tsa Tšireletseho:
- 5-fluoro-2-nitrobenzoic acid e nkoa e le motsoako o batlang o sireletsehile tlas'a maemo a tloaelehileng, empa o ntse o hloka ho tšoaroa ka hloko le ho latela mekhoa e nepahetseng ea liteko.
-Ha u kopana le motsoako ona, ho kopana le letlalo le tobileng le ho hema lerōle la lona ho lokela ho qojoa.
- Ts'ebetsong ea ts'ebeliso le polokelo, ka kopo sireletsa lisebelisoa tsa laboratori ka nepo, 'me u lumellane le litataiso tse nepahetseng tsa polokeho.
-Ha ho ka ba le kotsi kapa ho belaelloa hore ho na le chefo, batla thuso ea bongaka hang-hang 'me u tlise leqephe la polokeho ea komporo.
