Isingeniso
I-Ethyl 4,4-difluoropentanoate, ifomula yamakhemikhali C6H8F2O2, iyinhlanganisela yezinto eziphilayo. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:
Imvelo:
-Ukubukeka: uketshezi olungenambala
Isisindo samangqamuzana: 146.12g/mol
-Indawo yokubilisa: 142-143°C
-Ukuminyana: 1.119 g/mL
-I-Solubility: Incibilika kuzincibilikisi zemvelo, ezingancibiliki emanzini
-Ukuzinza: kuzinzile, kodwa kuyenzeka kalula ekukhanyeni, ekushiseni, kuma-oxidants nama-asidi
Sebenzisa:
-I-Ethyl 4,4-difluoropentanoate iyinhlangano ebalulekile ye-organic synthesis intermediate, enezinhlobonhlobo zezicelo emkhakheni wezokwelapha, i-pesticide kanye nodayi. Ingasetshenziswa njengesandulela sokuhlanganiswa kwemithi, izibulala-zinambuzane kanye nodayi, kanye nokulungiswa kwamanye ama-organic compounds.
- I-4,4-difluoropentanoic acid ethyl ester ingasetshenziswa njenge-solvent, i-esterification reagent kanye ne-catalyst ku-organic synthesis.
Indlela Yokulungiselela:
Ukulungiswa kwe-ethyl 4,4-difluoropentanoate ngokuvamile kwenziwa ngalezi zinyathelo ezilandelayo:
1. Okokuqala, i-pentanoic acid isabela nge-sulfur difluoride ukuze ithole i-4,4-difluoropentanoic acid.
I-2.4,4-difluoropentanoic acid bese isabela nge-ethanol ngaphansi kwezimo ze-acidic ukukhiqiza i-ethyl 4,4-difluoropentanoate.
Ulwazi Lokuphepha:
- I-4,4-difluoropentanoic acid i-ethyl ester iwuketshezi oluvuthayo, ukugcinwa nokusebenza kufanele kunake ukugwema umlilo nelangabi elivulekile.
-ukusetshenziswa kufanele kugqoke izibuko zokuzivikela namagilavu, gwema ukuthintana nesikhumba kanye nokuhogela umhwamuko wayo.
-Sebenzisa endaweni engenawo umoya ukuze ugweme ukungena ohlelweni lokuphefumula.
-Uma uthintwe ngephutha noma uthathwe ngephutha, hlambulula ngokushesha ngamanzi amaningi futhi ufune usizo lwezempilo ngokushesha.
