I-Ethyl 4,4-difluoropentanoate, i-chemical formula C6H8F2O2, i-organic compound. Oku kulandelayo yinkcazo yobume bayo, ukusetyenziswa, ukulungiswa kunye nolwazi lokhuseleko:
Indalo:
-Imbonakalo: ulwelo olungenambala
-Ubunzima bemolekyuli: 146.12g / mol
-Indawo yokuBilisa: 142-143°C
-Ubuninzi: 1.119 g/mL
-Ukunyibilika: Inyibilika kwizinyibilikisi eziphilayo, ezinganyibilikiyo emanzini
-Ukuzinza: izinzile, kodwa ziyakwazi ukukhanya, ukushisa, i-oxidants kunye ne-acids
Sebenzisa:
-Ethyl 4,4-difluoropentanoate yinto ebalulekileyo ye-organic synthesis intermediate, enoluhlu olubanzi lwezicelo kwiinkalo zonyango, i-pesticide kunye nemboni yedayi. Ingasetyenziselwa njenge-precursor ye-syntheutical of pharmaceuticals, i-pesticides kunye nedayi, kunye nokulungiselela ezinye izinto eziphilayo.
- I-4,4-difluoropentanoic acid ethyl ester ingasetyenziselwa njenge-solvent, i-esterification reagent kunye ne-catalyst kwi-organic synthesis.
Indlela yokulungiselela:
Ukulungiswa kwe-ethyl 4,4-difluoropentanoate ngokuqhelekileyo kuqhutywa ngala manyathelo alandelayo:
1. Okokuqala, i-pentanoic acid iphendulwa kunye ne-sulfur difluoride ukufumana i-4,4-difluoropentanoic acid.
I-2.4,4-difluoropentanoic acid ke isabela nge-ethanol phantsi kweemeko ze-acidic ukuvelisa i-ethyl 4,4-difluoropentanoate.
Ulwazi ngoKhuseleko:
- 4,4-difluoropentanoic acid ethyl ester lulwelo olunokutsha, ukugcinwa kunye nokusebenza kufuneka ingqalelo ukuphepha umlilo kunye nedangatye evulekileyo.
-ukusetyenziswa kufuneka kunxibe iiglasi zokukhusela kunye neiglavu, ugweme ukudibanisa nesikhumba kunye ne-inhalation yomphunga wayo.
-Sebenzisa kwindawo enomoya kakuhle ukuze ugweme ukungena kwinkqubo yokuphefumula.
-Ukuba uchukumise ngephutha okanye uthathwe ngempazamo, hlambulula ngokukhawuleza ngamanzi amaninzi kwaye ufune unyango ngokukhawuleza.
