Intangiriro
Ethyl 4,4-difluoropentanoate, formula ya chimique C6H8F2O2, nikintu kama. Ibikurikira nubusobanuro bwimiterere yabyo, imikoreshereze, imyiteguro namakuru yumutekano:
Kamere:
-Ibigaragara: amazi adafite ibara
-Uburemere bwa molekulari: 146.12g / mol
-Icyerekezo: 142-143 ° C.
-Ubucucike: 1.119 g / mL
-Gukemuka: Gushonga mumashanyarazi kama, kudashonga mumazi
-Guhungabana: bihamye, ariko byoroshye urumuri, ubushyuhe, okiside na acide
Koresha:
-Ethyl 4,4-difluoropentanoate ningirakamaro hagati ya synthesis organique hagati, ifite uburyo bwinshi bwo gukoresha mubijyanye n'ubuvuzi, imiti yica udukoko n’inganda. Irashobora gukoreshwa nkibibanziriza guhuza imiti, imiti yica udukoko n amarangi, kimwe no gutegura ibindi bintu kama.
- 4,4-difluoropentanoic aside Ethyl ester irashobora gukoreshwa nka solvent, esterification reagent na catalizator muri synthesis.
Uburyo bwo Gutegura:
Gutegura Ethyl 4,4-difluoropentanoate muri rusange bikorwa nintambwe zikurikira:
1. Ubwa mbere, aside pentanoic ikorwa na sulfur difluoride kugirango ibone aside 4,4-difluoropentanoic.
Acide 2.4,4-difluoropentanoic noneho ikorwa na Ethanol mugihe cya acide kugirango itange Ethyl 4,4-difluoropentanoate.
Amakuru yumutekano:
- 4,4-difluoropentanoic aside Ethyl ester ni amazi yaka umuriro, kubika no gukora bigomba kwitondera kwirinda umuriro numuriro ufunguye.
-koresha ugomba kwambara ibirahuri bikingira hamwe na gants, wirinde guhura nuruhu no guhumeka umwuka wacyo.
-Korera ahantu hafite umwuka uhagije kugirango wirinde kwinjira mubuhumekero.
-Niba byakozwe ku bw'impanuka cyangwa byafashwe n'ikosa, kwoza ako kanya n'amazi menshi hanyuma uhite witabaza.
