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

Loaʻa iā Ethyl 4,4-difluoro-3-oxobutyrate kahi ʻano hana kahi i hoʻopili ʻia ai kahi hui difluoromethyl (-CF2) i kahi iwi kuamoʻo β-ketoester, a ua pani ʻia kekahi o nā hydrogens e kahi hui ethyl (-C2H5). Hoʻopili kēia hoʻonohonoho ʻano hana i kona mau ʻano kino a me ke kemika. Loaʻa pinepine ia ma ke ʻano he wai kala ʻole me kahi kiko paila ma kahi o 130 ° C a me kahi density o kahi 1.27 g / cm³. He mea hoʻoheheʻe iki ka hui i ka wai akā hoʻoheheʻe koke i nā mea hoʻoheheʻe organik e like me ka ethanol a me ka acetone. Hoʻohana ʻOihana ʻAla: Hoʻohana nui ʻia ʻo Ethyl 4,4-difluoro-3-oxobutyrate ma ka ʻāpana ʻala ma muli o kona ʻala hua. Hana ia ma ke ʻano he mea waiwai nui i nā mea ʻala, colognes, a me nā huahana ʻala ʻē aʻe. Hana Kemika: Hana ka hui ma ke ʻano he poloka hale versatile i ka synthesis organik. Komo ia i nā ʻano hana like ʻole e hana i nā derivatives he mea nui i nā ʻoihana lāʻau lapaʻau a me ka agrochemical. Waena: I loko o ke kemika organik, lawelawe ʻo ethyl 4,4-difluoro-3-oxobutyrate ma ke ʻano he waena no ka synthesis o nā hui paʻakikī, e kōkua ana i ka hoʻomohala ʻana i nā mea hou a me nā kaʻina hana kemika. Synthesis Hiki ke synthesized ʻia ʻo Ethyl 4,4-difluoro-3-oxobutyrate ma o kekahi mau ʻano. ʻO kahi ala maʻamau e pili ana i ka hopena ma waena o ka ethyl acetoacetate a me 2,2-difluoroethyl bromide ma lalo o nā kūlana kumu. ʻO kēia hopena e alakaʻi i ka hoʻokumu ʻia ʻana o ka ethyl 4,4-difluoro-3-oxobutyrate ma ke ʻano he huahana nui, a laila hiki ke hoʻomaʻemaʻe ʻia e loaʻa ai nā hua kiʻekiʻe a me ka maʻemaʻe. I ka hōʻuluʻulu manaʻo, ʻo ka ethyl 4,4-difluoro-3-oxobutyrate kahi hui versatile e pono ai i ka hana ʻala, ka synthesis kemika, a me nā noi ʻoihana. ʻO kona mau waiwai kūikawā, me ka solubility a me ke ʻano kemika kikoʻī, e waiwai nui ia ma nā ʻāpana like ʻole, e hāʻawi nui ana i ka hoʻokumu ʻana o nā huahana mea kūʻai aku a me nā huahana ʻoihana like ʻole.
