Nhanganyaya

2,5-Difluorobenzoic asidhi.

Solubility: 2,5-difluorobenzoic acid ine yakaderera solubility mumvura uye yakanaka solubility mune organic solvents akadai ethanol uye dimethylformamide.

Acidic: Icho chinhu chine acidic chinopindirana kuita munyu unoenderana uye esters.

 

2,5-Difluorobenzoic acid ine zvimwe zvakakosha zvinoshandiswa muindasitiri, kusanganisira:

 

Mushonga wezvipembenene wepakati: unogona kushandiswa sepakati mukugadzira mimwe mishonga yekuuraya zvipembenene, senge oxalic acid herbicides.

Dye synthesis: Chigadzirwa chinogona kushandiswa kugadzira dhayi chaiyo.

 

Nzira yekugadzirira 2,5-difluorobenzoic acid inogona kazhinji kuitwa nematanho anotevera:

 

Chekutanga, maatomu maviri ehydrogen ari mubenzoic acid anotsiviwa nemaatomu efluorine achishandisa fluorinating agent kuwana 2,5-difluorobenzoic acid.

 

Paunenge uchishandisa kana kubata 2,5-difluorobenzoic acid, kungwarira kunofanirwa kutorwa kuti uteerere kune inotevera ruzivo rwekuchengetedza:

 

Dzivisa inhalation: Kugara kwenguva refu kana kufema kwe2,5-difluorobenzoic acid poda kana mhute inofanira kudziviswa kuti irege kukanganisa nzira yekufema nemapapu.

Kubata maziso neganda: Shamba nekukasika nemvura yakawanda kana wasangana nemaziso kana ganda.

Kushandiswa kwemidziyo yekuzvidzivirira: Magirovhosi akakodzera, magirazi, uye zvipfeko zvinodzivirira zvinofanira kupfekwa pakubata 2,5-difluorobenzoic acid.

Chengetedzo Yekuchengetedza: 2,5-difluorobenzoic acid inofanira kuchengetwa munzvimbo yakaoma, ine mhepo yakanaka, kudzivisa kusangana nezvinhu zvinopisa, uye kure nemoto.
