I-Ethyl 4,4-difluoro-3-oxobutyrate CAS:352-24-9

I-Ethyl 4,4-difluoro-3-oxobutyrate inesakhiwo apho iqela le-difluoromethyl (-CF2) linamathele kumqolo we-β-ketoester, kwaye enye yee-hydrogens ithathelwa indawo liqela le-ethyl (-C2H5). Olu lwakhiwo luchaphazela iimpawu zalo zomzimba nezekhemikhali. Ihlala ikhona njengolwelo olungenambala olunendawo yokubila malunga ne-130°C kunye noxinano olumalunga ne-1.27 g/cm³. I-compound ayinyibiliki emanzini kodwa inyibilika ngokulula kwizinyibilikisi ze-organic ezifana ne-ethanol kunye ne-acetone. Ukusetyenziswa Ishishini Levumba: I-Ethyl 4,4-difluoro-3-oxobutyrate isetyenziswa kakhulu kwicandelo levumba ngenxa yevumba layo leziqhamo. Isebenza njengesithako esibalulekileyo kwiivumba, ii-colognes, kunye nezinye iimveliso zevumba. Ukwenziwa kweeKhemikhali: I-compound isebenza njengebhloko yokwakha eguquguqukayo kwi-organic synthesis. Ithatha inxaxheba kwiimpendulo ezahlukeneyo ukuvelisa izinto eziphuma kwizinto ezibalulekileyo kumashishini amayeza kunye neekhemikhali zezolimo. I-Intermediate: Kwi-organic chemistry, i-ethyl 4,4-difluoro-3-oxobutyrate isebenza njenge-intermediate yokwenziwa kwee-compounds ezintsonkothileyo, inegalelo ekuphuhlisweni kwezinto ezintsha kunye neenkqubo zeekhemikhali. Ukwenziwa kwe-Ethyl 4,4-difluoro-3-oxobutyrate kunokwenziwa ngeendlela ezahlukeneyo. Enye indlela eqhelekileyo ibandakanya impendulo phakathi kwe-ethyl acetoacetate kunye ne-2,2-difluoroethyl bromide phantsi kweemeko ezisisiseko. Le mpendulo ikhokelela ekwakhiweni kwe-ethyl 4,4-difluoro-3-oxobutyrate njengemveliso ephambili, enokuthi emva koko ihlanjululwe ukuze kufunyanwe isivuno esiphezulu kunye nobunyulu. Ngamafutshane, i-ethyl 4,4-difluoro-3-oxobutyrate yi-compound eguquguqukayo ebalulekileyo ekudalweni kwevumba elimnandi, ukwenziwa kweekhemikhali, kunye nokusetyenziswa kwemizi-mveliso. Iimpawu zayo ezahlukileyo, kubandakanya ukunyibilika kunye nolwakhiwo oluthile lweekhemikhali, ziyenza ibe luncedo kumacandelo ahlukeneyo, inegalelo elikhulu ekwakhiweni kweemveliso ezahlukeneyo zabathengi kunye nemizi-mveliso.
