Selelekela

3-nitro-4-fluorobenzoic acid ke motsoako oa manyolo. Se latelang ke selelekela sa thepa ea eona, tšebeliso, mekhoa ea tlhahiso, le tlhaiso-leseling ea polokeho:

 

Boleng:

- Ponahalo: E tiileng ka kristale e tšoeu.

- Sollubility: ha e qhibilihe ka metsing, e qhibiliha hanyane ka har'a joala le li-ethers.

 

Sebelisa:

- 3-Nitro-4-fluorobenzoic acid e sebelisoa haholo-holo e le karolo e bohareng ea liketso tsa organic synthesis.

 

Mokhoa:

- 3-nitro-4-fluorobenzoic acid e ka fumanoa ka karabelo ea sebaka sa p-nitrotoluene. Mehato e tobileng ke ho qala ka ho kenya fluorine sebakeng sa nitrotoluene tlas'a maemo a acidic ho fumana 3-nitro-4-fluorotoluene, 'me joale karabelo e eketsehileng ea oxidation ho fumana 3-nitro-4-fluorobenzoic acid.

 

Lintlha tsa Tšireletseho:

- 3-nitro-4-fluorobenzoic acid e ka ba chefo ho batho, e halefisa mahlo le letlalo.

- Ha u sebelisa, qoba ho kopana le letlalo le mahlo ka ho toba, 'me u sebelise liatlana tse sireletsang le likhalase ha ho hlokahala.

- Nakong ea polokelo, e lokela ho bolokoa sebakeng se lefifi, se omeletseng, se pholileng, hole le mollo le li-oxidants.

- Ha u lahla litšila, ka kopo latela melao e nepahetseng ea polokeho ho thibela tšilafalo ea tikoloho.
