Hordhac
Ethyl 4,4-difluoropentanoate, formula kiimikaad C6H8F2O2, waa iskudhis organic ah. Kuwa soo socda waa sharaxaadda dabeecadeeda, isticmaalkeeda, diyaarinteeda iyo macluumaadka badbaadada:
Dabeecadda:
-Muuqaalka: dareere aan midab lahayn
-Miisaanka molecular: 146.12g/mol
-Bulshada karkarinta: 142-143°C
-cufnaanta: 1.119 g/ml
-Milan: Waxay ku milmi karaan dareerayaasha organic, oo aan lagu milmin biyaha
-Xasilooni: xasiloon, laakiin u nugul iftiinka, kulaylka, oxidants iyo acids
Isticmaal:
-Ethyl 4,4-difluoropentanoate waa mid dhexdhexaad ah oo ka mid ah isku-dhafka dabiiciga ah, kaas oo leh codsiyo badan oo kala duwan oo ku saabsan dhinacyada daawada, sunta cayayaanka iyo warshadaha dheeha. Waxaa loo isticmaali karaa horudhac u ah isku-darka dawooyinka, sunta cayayaanka iyo dheeha, iyo sidoo kale diyaarinta xeryahooda kale ee organic.
-4,4-difluoropentanoic acid ethyl ester waxaa loo isticmaali karaa sida dareere, reagent esterification iyo kicinta in synthesis organic.
Habka Diyaarinta:
Diyaarinta ethyl 4,4-difluoropentanoate guud ahaan waxaa lagu fuliyaa tillaabooyinka soo socda:
1. Marka hore, pentanoic acid waxaa lagu falceliyaa sulfur difluoride si loo helo 4,4-difluoropentanoic acid.
2.4,4-difluoropentanoic acid ayaa markaa la falcelisa ethanol ee xaaladaha acidic si loo dhaliyo ethyl 4,4-difluoropentanoate.
Macluumaadka Badbaadada:
-4,4-difluoropentanoic acid ethyl ester waa dareere guban kara, kaydinta iyo qalliinka waa in fiiro gaar ah loo yeesho si looga fogaado dabka iyo ololka furan.
Isticmaalku waa inuu xidho muraayadaha difaaca iyo galoofyada, iska ilaali taabashada maqaarka iyo neefsashada uumiga.
-Ka shaqee meel hawo fiican leh si aad uga fogaato gelitaanka habka neefsashada.
-Haddii si qalad ah loo taabto ama si qalad ah loo qaato, isla markiiba ku luqluq biyo badan oo raadso daryeel caafimaad isla markiiba.
