Isingeniso
I-3,4-difluorobenzotrifluoride iyinhlanganisela yemvelo enefomula yamakhemikhali ethi C7H2F5. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:
Imvelo:
-Ukubukeka: I-3,4-difluorobenzotrifluoride iwuketshezi olungenambala.
-Indawo yokuncibilika: -35 ° C
-Indawo yokubilisa: 114 ° C
-Ukuminyana: 1.52g/cm³
-Ukunyibilika: Kuncibilika ezincibilikisini eziningi eziphilayo, njenge-ethanol, i-ether ne-benzene.
Sebenzisa:
-3,4-difluorobenzotrifluoride ivame ukusetshenziswa njenge-solvent ye-organic synthesis reactions. I-solubility yayo ephezulu kanye nemvelo e-anhydrous ikwenza kube isicelo esibalulekile ku-organic synthesis.
-Ingasetshenziswa futhi njenge-ejenti yokwelashwa kwendawo kanye ne-ejenti yokuhlanza.
Indlela:
-3,4-difluorobenzotrifluoride ingatholakala ngokusabela i-3,4-difluorophenyl hydrogen sulfide ne-barium trifluoride. Izimo zokusabela ngokuvamile ziba sebukhoneni be-magnesium chloride, ukushisisa amahora ambalwa, bese kwelapha okuphakathi okuwumphumela ngotshwala.
Ulwazi Lokuphepha:
-3,4-difluorobenzotrifluoride iyinhlanganisela yemvelo eguquguqukayo, futhi ukuhogela komhwamuko wayo kufanele kugwenywe.
-Gqoka izinto zokuzivikela ezifanele njengezibuko, amagilavu nezingubo zokuzivikela uma zisetshenziswa.
-Ukuchayeka isikhathi eside noma okusindayo kungaba yingozi empilweni futhi kungabangela ukucasuka kwamehlo, ukuphefumula kanye nesikhumba.
-okusetshenziswayo nokugcinwa kufanele kunake izinyathelo zokuvimbela umlilo nokuqhuma, gwema ukuthintana nama-oxidants aqinile.
-Uma ngephutha uchaphaze emehlweni akho noma uthinte isikhumba sakho, hlambulula ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha.
