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

Ethyl 4,4-difluoro-3-oxobutyrate ifite imiterere aho itsinda rya difluoromethyl (-CF2) rifatanye n'umugongo wa β-ketoester, naho imwe muri hydrogene igasimburwa n'itsinda rya ethyl (-C2H5). Iyi miterere y'imiterere igira ingaruka ku miterere yayo y'umubiri n'iya shimi. Ubusanzwe iba nk'amazi adafite ibara afite ubushyuhe bugera kuri 130°C n'ubucucike bwa 1.27 g / cm³. Iki kinyabutabire gishongeshwa gake mu mazi ariko kigashonga byoroshye mu bintu bishongeshwa nka ethanol na acetone. Ikoreshwa Inganda zitanga impumuro nziza: Ethyl 4,4-difluoro-3-oxobutyrate ikoreshwa cyane mu rwego rw'impumuro nziza bitewe n'impumuro yayo y'imbuto. Ikora nk'ikintu cy'agaciro mu birungo bihumura neza, colognes, n'ibindi bicuruzwa bihumura neza. Gutunganya ibirungo: Iki kinyabutabire gikora nk'inkingi ikomeye mu gushushanya ibirungo bikomoka ku bi ... Hagati: Muri chimie y’ibinyabuzima, ethyl 4,4-difluoro-3-oxobutyrate ikora nk'interuro yo guhuza imvange zigoye cyane, igafasha mu iterambere ry’ibikoresho bishya n’imikorere ya chimie. Ikorwa rya Ethyl 4,4-difluoro-3-oxobutyrate rishobora gukorwa hakoreshejwe uburyo butandukanye. Uburyo bumwe busanzwe burimo uburyo hagati ya ethyl acetoacetate na 2,2-difluoroethyl bromide mu bihe by’ibanze. Ubu buryo butuma habaho ethyl 4,4-difluoro-3-oxobutyrate nk'ikintu nyamukuru, hanyuma kigatunganywa kugira ngo kibone umusaruro mwinshi n'ubuziranenge. Muri make, ethyl 4,4-difluoro-3-oxobutyrate ni ikintu cy’ingenzi mu gukora impumuro nziza, guhuza imikorere ya chimie, no gukoreshwa mu nganda. Imiterere yayo yihariye, harimo gushonga no gushonga n'imiterere yihariye ya chimie, ituma igira agaciro mu nzego zitandukanye, igira uruhare runini mu gukora ibicuruzwa bitandukanye by’abaguzi n’inganda.
