Methylacetoacetate CAS: 105-45-3

Methylacetoacetate e na le ditiriso tse fapaneng le tsa bohlokwa mafapheng a fapaneng. Ka ho kopanya dintho tse phelang, e sebetsa e le motheo wa bohlokwa bakeng sa ho lokisa meriana, dikhemikhale tsa temo le dikhemikhale tse ntle. Karabelo ya yona e ikgethang e dumella ho kenngwa ha dihlopha tse fapaneng tsa tshebetso, e leng se etsang hore e be ya bohlokwa k'hemistring ya meriana le ntshetsopeleng ya dithethefatsi. Ho feta moo, di-derivatives tsa Methylacetoacetate di hlahlobilwe ka lebaka la mesebetsi ya tsona e ka bang teng ya baeloji, ho kenyeletswa le thepa ya ho lwantsha dikokwana-hloko, ho lwantsha dikokwana-hloko le ho lwantsha kankere. Karolo ya yona jwalo ka mofani wa Michael diphetohong tsa dintho tse phelang e kentse letsoho tshebedisong ya yona ka ho kopanya dintho tse sa lekanang, e leng se nolofalletsang ho thehwa ha dimolek'hule tsa chiral tse hlokahalang ntshetsopeleng ya dithethefatsi. Ho feta moo, Methylacetoacetate e sebediswa tlhahisong ya di-pyrazole, e leng di-intermediate tsa bohlokwa ka hara dikhemikhale tsa meriana le tsa temo. Ho kenella ha yona ka hara ho kopanya dintho tse phelang ho totobatsa bohlokwa ba yona ka ho theha dibopeho tse rarahaneng tsa dikhemikhale. Ho feta moo, motsoako ona o sebediswa ka ho etsa didae, di-pigment le di-UV absorbers, e leng se bontshang hore e ka sebediswa haholo indastering ya dikhemikhale. Ka kakaretso, mefuta e mengata ya tshebediso ya Methylacetoacetate e totobatsa bohlokwa ba yona ka ho ntshetsa pele dikhemistri tsa dintho tse phelang le dipatlisiso tsa meriana.
