ethyl 4,4,4-trifluoroacetoacetate CAS: 372-31-6

Ethyl 4,4,4-trifluoroacetoacetate, izwi kandi nka ethyl trifluoroacetoacetate, ni amazi atagira ibara arangwa n'impumuro yayo ikarishye kandi y'imbuto. Ifite formula ya shimi C6H6F3O3, igira uruhare runini mu nganda zitandukanye bitewe n'imiterere yayo yihariye ya shimi. Imiterere Ethyl 4,4,4-trifluoroacetoacetate ifite imiterere aho itsinda rya trifluoromethyl (-CF3) rifatanye n'umugongo wa β-ketoester, kandi imwe muri hydrogens igasimburwa n'itsinda rya ethyl (-C2H5). Iyi miterere igira ingaruka ku miterere yayo y'umubiri n'iya shimi. Ubusanzwe igaragara nk'amazi atagira ibara afite ubushyuhe bugera kuri 120°C n'ubucucike bwa 1.35 g/cm³. Nubwo ishongesha gato mu mazi, ishongesha byoroshye mu bintu bishongesha nk'ethanol na acetone. Ikoreshwa Inganda z'impumuro nziza: Ethyl 4,4,4-trifluoroacetoacetate ikundwa cyane mu rwego rw'impumuro nziza kubera impumuro yayo ikarishye kandi y'imbuto. Ikoreshwa cyane mu bihumura neza, ibinure, n'ibindi bicuruzwa bihumura neza kugira ngo itange impumuro nziza. Gutunganya ibinyabutabire: Iki kinyabutabire gikora nk'ikintu cy'ingenzi mu guhuza ibinyabutabire. Gikora mu buryo butandukanye kugira ngo kibone ibintu by'ingenzi mu miti, ibinyabutabire by'ubuhinzi, n'ibindi binyabutabire byihariye, bitewe n'uburyo kidasanzwe bwo gukora ibinyabutabire. Inyongerera uburyohe: Uretse uruhare rwayo mu bihumura neza, ethyl 4,4,4-trifluoroacetoacetate ikoreshwa mu nganda z'ibiribwa nk'inyongeramusaruro bitewe n'impumuro yayo nziza. Gutunganya Ethyl 4,4,4-trifluoroacetoacetate ishobora gukorwa hakoreshejwe uburyo butandukanye. Uburyo busanzwe burimo uburyohe hagati ya ethyl acetoacetate na aside trifluoroacetic mu gihe hagenzurwa. Ubu buryo butanga ethyl 4,4,4-trifluoroacetoacetate nk'umusaruro w'ingenzi, hanyuma igashobora gusukurwa kugira ngo igere ku musaruro mwinshi n'ubuziranenge bukwiriye gukoreshwa mu nganda. Muri make, ethyl 4,4,4-trifluoroacetoacetate ni ikintu cy’ingenzi mu gukora impumuro nziza, gukora imiti, no gukoresha mu nganda zitandukanye. Imiterere yayo itandukanye, harimo gushonga no gushonga mu buryo bwihariye, ituma iba ingenzi mu nzego nyinshi, igira uruhare runini mu gukora ibicuruzwa bitandukanye bikoreshwa n’abaguzi n’inganda.
