Mawu Oyamba
Ethyl 2-choro-3-keto-4, 4,4-trifluorobutyrate ndi organic pawiri ndi mankhwala formula C6H7ClF3O3. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:
Chilengedwe:
-Maonekedwe: Madzi opanda mtundu kapena opepuka achikasu
-Posungunuka: -60°C
-Kutentha: 118-120°C
-Kuchulukana: 1.432 g/mL
-Kusungunuka: Kusungunuka m'madzi ndi zosungunulira zambiri
Gwiritsani ntchito:
- ethyl 2-chroo-3-keto-4, 4,4-trifluorobutyrate nthawi zambiri amagwiritsidwa ntchito ngati reagent yofunika mu kaphatikizidwe ka organic. Itha kugwiritsidwa ntchito popanga zinthu zina, monga mankhwala, mankhwala ophera tizilombo, utoto, ndi zina.
-Itha kugwiritsidwanso ntchito ngati chowonjezera pazinthu zaulimi antifouling agent, utoto ndi guluu.
Njira Yokonzekera:
Kaphatikizidwe ka ethyl 2-chloro-3-keto-4,4,4-trifluorobutyrate nthawi zambiri imachitika ndi izi:
1.2-chloro-4, 4,4-trifluoroacetic acid imakumana ndi chloroacetic anhydride kupanga 2-chloro-4, 4,4-trifluoroacetyl chloride.
2.2-chloro-4, 4,4-trifluoroacetyl chloride ndiye amachitidwa ndi ethyl acetate kuti apange chomaliza cha ethyl 2-chloro-3-keto-4, 4,4-trifluobutyrate.
Zambiri Zachitetezo:
-Ethyl 2-chloro-3-keto-4,4,4-trifluorobutyrate ndi chinthu chosasinthika chomwe chingayambitse ngozi zodziwika kapena zomwe zingachitike paumoyo.
-Pamene ntchito ayenera kutsatira njira chitetezo, monga kuvala magalasi zoteteza ndi magolovesi.
-Pewani kukhudzana ndi khungu ndi maso, pewani kutulutsa nthunzi wake, komanso kukhala ndi mpweya wabwino.
-Posunga, samalani kuti mupewe moto ndi kutentha kwambiri, komanso pewani moto ndi zinthu zomwe zimatha kuyaka.
Chonde dziwani kuti pakugwiritsa ntchito ndi kusamalira mankhwala, njira zoyendetsera bwino ziyenera kutsatiridwa, ndipo Material Safety Data Sheet (MSDS) iyenera kuwerengedwa ndikutsatiridwa.
