-Kuwanda: 1.432 g/mL
-Solubility: Soluble mumvura uye yakawanda organic solvents
Shandisa:
- ethyl 2-chroo-3-keto-4, 4,4-trifluorobutyrate inowanzoshandiswa sechinhu chakakosha reagent mu organic synthesis. Inogona kushandiswa kugadzira mamwe makomisheni, akadai semishonga, mishonga yezvipembenene, dhayi, nezvimwe.
-Inogona zvakare kushandiswa sekuwedzera kune zvigadzirwa zvekurima antifouling agent, pendi uye glue.
Kugadzirira nzira:
Iyo synthesis ye ethyl 2-chloro-3-keto-4,4,4-trifluorobutyrate inowanzoitwa nematanho anotevera:
1.2-chloro-4, 4,4-trifluoroacetic acid inopindirana nechloroacetic anhydride kugadzira 2-chloro-4, 4,4-trifluoroacetyl chloride.
2.2-chloro-4, 4,4-trifluoroacetyl chloride inobva yaitwa ne ethyl acetate kuti ibudise chigadzirwa chekupedzisira ethyl 2-chloro-3-keto-4, 4,4-trifluobutyrate.
Zvekuchengetedza
-Ethyl 2-chloro-3-keto-4,4,4-trifluorobutyrate is volatile organic compound iyo inogona kukonzera inozivikanwa kana inogona kukuvadza hutano.
-Paunenge uchishandiswa unofanirwa kutevedzera nzira dzekuchengetedza, sekupfeka magirazi ekudzivirira uye magirovhosi.
-Dzivisa kusangana neganda nemaziso, dzivisa kupinza mhute yaro, uye chengetedza mhepo yakanaka.
-Paunenge uchichengeta, teerera kudzivirira moto uye kupisa kwakanyanya, uye chengetedza kure nemoto uye zvinhu zvinopisa.
Ndokumbira utarise kuti pakushandisa uye kubata makemikari, nzira dzekushandisa dzakachengeteka dzinofanirwa kuteverwa, uye inowirirana Material Safety Data Sheet (MSDS) inofanira kunyatsoverengwa nekuteverwa.
