-I-Solubility: Inyibilika emanzini kunye nezinyibilikisi ezininzi zendalo
Sebenzisa:
- ethyl 2-chroo-3-keto-4, 4,4-trifluorobutyrate isoloko isetyenziswa njenge-reagent ebalulekileyo kwi-organic synthesis. Ingasetyenziselwa ukudibanisa ezinye iikhompawundi, ezifana neziyobisi, izitshabalalisi, iidayi, njl.
-Inokuthi isetyenziswe njengesongezo kwiimveliso zezolimo i-antifouling agent, ipeyinti kunye neglue.
Indlela yokulungiselela:
Ukwenziwa kwe-ethyl 2-chloro-3-keto-4,4,4-trifluorobutyrate idla ngokuqhutywa ngala manyathelo alandelayo:
I-1.2-chloro-4, i-4,4-trifluoroacetic acid isabela nge-chloroacetic anhydride ukuvelisa i-2-chloro-4, 4,4-trifluoroacetyl chloride.
I-2.2-chloro-4, 4,4-trifluoroacetyl chloride iphinda iphendule nge-ethyl acetate ukuvelisa imveliso yokugqibela ye-ethyl 2-chloro-3-keto-4, 4,4-trifluobutyrate.
Ulwazi ngoKhuseleko:
-I-Ethyl 2-chloro-3-keto-4,4,4-trifluorobutyrate yinto eguquguqukayo ye-organic compound enokubangela ukwaziwa okanye ubungozi bempilo.
-Xa ukusetyenziswa kufuneka kuhambelane neenkqubo zokhuseleko, ezifana nokunxiba iiglasi zokukhusela kunye neiglavu.
-Kuphephe ukudibana nolusu kunye namehlo, kuphephe ukuphefumla umphunga walo, kwaye ugcine umoya olungileyo.
-Xa ugcina, qaphela ukuphepha umlilo kunye nokushisa okuphezulu, kwaye ugcine kude nomlilo kunye nezinto ezinokutsha.
Nceda uqaphele ukuba ukusetyenziswa kunye nokuphathwa kweekhemikhali, iinkqubo zokusebenza ezikhuselekileyo kufuneka zilandelwe, kwaye i-Material Safety Data Sheet (MSDS) ehambelana nayo kufuneka ifundwe ngononophelo kwaye ilandelwe.
