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

Ethyl 4,4,4-trifluoroacetoacetate, inozivikanwawo se ethyl trifluoroacetoacetate, imvura isina ruvara inozivikanwa nekunhuhwirira kwayo kwakapinza uye kwemuchero. Iine fomura yemakemikari C6H6F3O3, inoita basa rakakosha mumaindasitiri akasiyana-siyana nekuda kwehunhu hwayo hwakasiyana hwemakemikari. Hunhu Ethyl 4,4,4-trifluoroacetoacetate ine chimiro apo boka re trifluoromethyl (-CF3) rinonamirwa kumusana we β-ketoester, uye rimwe rema hydrogens rinotsiviwa neboka re ethyl (-C2H5). Kurongeka uku kwechimiro kunokanganisa hunhu hwayo hwepanyama uye hwemakemikari. Inowanzoonekwa semvura isina ruvara ine poindi yekufashaira inosvika 120°C uye density inosvika 1.35 g/cm³. Kunyangwe ichinyungudika zvishoma mumvura, inonyungudika nyore nyore muzvinhu zvakasikwa zvakaita se ethanol ne acetone. Mashandisirwo Indasitiri Yekunhuhwirira: Ethyl 4,4,4-trifluoroacetoacetate inokosheswa zvikuru muchikamu chekunhuhwirira nekuda kwekunhuhwirira kwayo kwakapinza uye kwemuchero. Inoshandiswa zvakanyanya muzvinonhuwira, colognes, nezvimwe zvigadzirwa zvinonhuwirira kuti ipe manotsi akasiyana ekunhuhwirira. Kugadzira Makemikari: Musanganiswa uyu unoshanda sechikamu chinoshanduka-shanduka mukugadzirwa kwezvinhu zvakasikwa. Unobatanidzwa mukuita kwakasiyana-siyana kugadzira zvinhu zvakakosha mumishonga, agrochemicals, uye makemikari akakosha, nekuda kwekuita kwayo kwakasiyana kwemakemikari. Kuvandudza Kunaka: Kuwedzera kune basa rayo mukunhuhwirira, ethyl 4,4,4-trifluoroacetoacetate inoshandiswa muindasitiri yechikafu sekuwedzera kunaka nekuda kwekunhuhwirira kwayo kwemichero. Kugadzira Ethyl 4,4,4-trifluoroacetoacetate inogona kugadzirwa nenzira dzakasiyana-siyana. Nzira yakajairika inosanganisira kuita pakati peethyl acetoacetate netrifluoroacetic acid mumamiriro ezvinhu akadzorwa. Kuita uku kunoburitsa ethyl 4,4,4-trifluoroacetoacetate sechigadzirwa chikuru, icho chinogona kuzocheneswa kuti chiwane goho rakakura uye kuchena kwakakodzera kushandiswa mumaindasitiri. Muchidimbu, ethyl 4,4,4-trifluoroacetoacetate chinhu chinoshandiswa zvakasiyana-siyana chakakosha mukugadzira kunhuhwirira, kugadzira makemikari, uye kushandiswa kwakasiyana-siyana mumaindasitiri. Hunhu hwayo hwakasiyana, kusanganisira kunyungudika uye chimiro chemakemikari chaiwo, zvinoita kuti ive yakakosha muzvikamu zvakasiyana-siyana, zvichibatsira zvikuru mukugadzirwa kwezvinhu zvakasiyana-siyana zvevatengi nemaindasitiri.
