Isingeniso
I-3-Bromo-5-(trifluoromethyl)benzoic acid iyinhlanganisela yezinto eziphilayo. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:
Imvelo:
-Ukubukeka: I-crystalline emhlophe eqinile
-Ifomula yemolekyuli: C8H4BrF3O2
Isisindo samangqamuzana: 269.01g/mol
-Indawo yokuncibilika: 156-158 ℃
Sebenzisa:
- I-3-Bromo-5-(trifluoromethyl) i-benzic acid isetshenziswa kabanzi emkhakheni we-organic synthesis njenge-reagent futhi ephakathi.
-Isetshenziswa njenge-synthetic intermediate yamadayi nezingulube.
-Isetshenziselwa ukulungisa amanye ama-organic compounds, njengama-fungicides, izidakamizwa, njll.
Indlela:
Ukulungiswa kwe-3-Bromo-5-(trifluoromethyl)benzoic acid kungenziwa ngezinyathelo ezilandelayo:
1. i-benzoic acid ihlangana ne-trifluoromethyl magnesium bromide ukukhiqiza usawoti we-magnesium ongu-3-Bromo-5-(trifluoromethyl)benzoic acid.
2. Usawoti we-magnesium okhiqiziwe usabela ne-asidi ukuze ukhulule i-3-Bromo-5-(trifluoromethyl)benzoic acid.
Ulwazi Lokuphepha:
- I-3-Bromo-5-(trifluoromethyl)benzoic acid kufanele isetshenziswe endaweni enomoya omuhle ukugwema ukuhogela noma ukuthinta isikhumba.
-esetshenziswayo nasekugcinweni kwayo, idinga ukunaka izindlela zokuvikela umlilo kanye nokuvikela ukuqhuma.
-Le nhlanganisela i-organic futhi ingase ibe usongo emvelweni. Imfucuza kufanele iphathwe ngokucophelela.
-Landela izinqubo zokuphepha zamakhemikhali ezifanele ngesikhathi sokuphatha nokugcina.
