Intshayelelo
I-2,3,4-Trifluorobenzoic acid yi-organic compound. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, indlela yokulungiselela kunye nolwazi lokhuseleko:
Umgangatho:
- Inkangeleko: 2,3,4-trifluorobenzoic acid is a colorless crystalline solid.
- Ukunyibilika: Inyibilika kwizinyibilikisi eziphilayo ezifana ne-ethers kunye neealkoholi kwaye zinyibilika kancinane emanzini.
- Ukuzinza: Ukuzinza ngokulinganayo kwiqondo lokushisa, kodwa kunokuncitshiswa ngama-oxidants anamandla okanye ama-agent okunciphisa kumaqondo aphezulu.
- Ubuninzi: malunga. 1.63 g/cm³.
Sebenzisa:
- 2,3,4-Trifluorobenzoic acid isetyenziswa ngokuqhelekileyo njengento ebalulekileyo ephakathi kwi-organic synthesis.
- Isenokusetyenziswa njengesithinteli somlilo kwizinto zokwaleka, idayi, iiplastiki, kunye neepolima.
Indlela:
I-2,3,4-Trifluorobenzoic acid inokulungiswa ngezi ndlela zilandelayo zokwenziwa:
- I-Benzoic acid isabela nge-trifluoroacetyl chloride ukuvelisa i-2,3,4-trifluorobenzoyl chloride.
- Emva koko, i-2,3,4-trifluorobenzoyl chloride iphendulwa ngamanzi ukunika i-2,3,4-trifluorobenzoic acid.
Ulwazi ngoKhuseleko:
- Uthuli kunye nomphunga we-2,3,4-trifluorobenzoic acid unokubangela ukucaphuka kwamehlo, ulusu kunye nenkqubo yokuphefumla.
-Nxiba izixhobo ezifanelekileyo zokuzikhusela ezifana nempahla yamehlo ekhuselayo, iiglavu, kunye neemaski zokhuselo xa usebenzisa okanye uphethe.
- Xa ubonakaliswe kwi-compound, indawo echaphazelekayo kufuneka ihlanjwe ngokukhawuleza ngamanzi acocekileyo kwaye ingqalelo yonyango kufuneka ifunwe ngokukhawuleza.
- Xa ugcina kwaye uphatha, amanyathelo okhuseleko afanelekileyo kunye neenkqubo kufuneka ziqwalaselwe, ezifana nokugcina indawo enomoya kunye nokuphepha ukudibanisa nezinto ezingahambelaniyo.
