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

Ethyl 4,4-difluoro-3-oxobutyrate ine chimiro apo boka re difluoromethyl (-CF2) rinonamirwa kumusana we β-ketoester, uye rimwe rema hydrogens rinotsiviwa neboka re ethyl (-C2H5). Kurongeka uku kwechimiro kunokanganisa hunhu hwaro hwepanyama nemakemikari. Kazhinji kacho rinowanikwa semvura isina ruvara ine poindi yekufashaira inosvika 130°C uye density inosvika 1.27 g/cm³. Musanganiswa uyu haunyungudike mumvura asi unonyungudika nyore nyore muzvinhu zvinonyungudutsa zvakaita se ethanol ne acetone. Mashandisirwo Indasitiri Yekunhuhwirira: Ethyl 4,4-difluoro-3-oxobutyrate inoshandiswa zvakanyanya muchikamu chekunhuhwirira nekuda kwekunhuhwirira kwayo kwemuchero. Inoshanda sechinhu chakakosha muzvinonhuwira, colognes, nezvimwe zvigadzirwa zvekunhuhwirira. Kugadzirwa Kwemakemikari: Musanganiswa uyu unoshanda sechivakwa chinoshanduka-shanduka mukugadzirwa kweorganic. Unobatanidzwa mukuita kwakasiyana-siyana kugadzira zvinhu zvakakosha muindasitiri yemishonga neyekurima. Pakati nepakati: Mumakemikari echisikigo, ethyl 4,4-difluoro-3-oxobutyrate inoshanda senzira yepakati yekugadzira makemikari akaomarara, ichibatsira mukugadzirwa kwezvinhu zvitsva uye maitiro emakemikari. Kugadzira Ethyl 4,4-difluoro-3-oxobutyrate inogona kugadzirwa nenzira dzakasiyana-siyana. Imwe nzira yakajairika inosanganisira kuita pakati peethyl acetoacetate ne2,2-difluoroethyl bromide pasi pemamiriro ekutanga. Kuita uku kunotungamira pakuumbwa kweethyl 4,4-difluoro-3-oxobutyrate sechigadzirwa chikuru, icho chinogona kuzocheneswa kuti chiwane goho rakakura uye kuchena. Mukupfupisa, ethyl 4,4-difluoro-3-oxobutyrate chinhu chinoshanda zvakasiyana-siyana chakakosha mukugadzira kunhuhwirira, kugadzira makemikari, uye mashandisirwo emaindasitiri. Hunhu hwayo hwakasiyana, kusanganisira kunyungudika uye chimiro chemakemikari chaiwo, chinoita kuti ive yakakosha muzvikamu zvakasiyana-siyana, ichibatsira zvikuru mukugadzirwa kwezvigadzirwa zvakasiyana-siyana zvevatengi nemaindasitiri.
