ʻEtil difluoroacetate CAS:454-31-9

ʻO Ethyl difluoroacetate (EDA) i hōʻike ʻia e kona ʻano molekala, e hōʻike ana i kahi hui difluoromethyl (-CF2COOEt) i hoʻopili ʻia i kahi ʻāpana ethyl ester. Hāʻawi kēia ʻano i ke kūpaʻa koʻikoʻi a me ka reactivity i ka EDA, e kūpono ai no nā ʻano hana kemika a me nā noi. Loaʻa ka EDA ma ke ʻano he wai maopopo, kala ʻole me kahi kiko paila ma kahi o 100 ° C a hōʻike i ka solubility maikaʻi i nā mea hoʻoheheʻe organik e like me ka acetone a me ka ethyl acetate. ʻO kona kūpaʻa ma lalo o nā kūlana like ʻole e ʻae ai i kona hoʻohana pono ʻana i nā noiʻi hale hana a me nā kaʻina hana ʻoihana. Hoʻohana Organic Synthesis: Hana ʻo EDA ma ke ʻano he poloka hale koʻikoʻi i ka synthesis organik, ʻoi aku hoʻi i ka hoʻolauna ʻana o nā hui difluoromethyl i loko o nā mole organik. He mea nui kēia hiki no ka hoʻomohala ʻana i nā lāʻau lapaʻau, nā agrochemicals, a me nā kemika kūikawā me ka hana olaola i hoʻonui ʻia a me ke kūpaʻa kemika. Kemika lāʻau lapaʻau: I nā noi lāʻau lapaʻau, hoʻohana ʻia ʻo EDA ma ke ʻano he precursor i ka synthesis o nā mea hana lāʻau lapaʻau ikaika (APIs) ma muli o kona hiki ke hāʻawi i nā waiwai pharmacological makemake ʻia. He kuleana koʻikoʻi ia i ka kemika lāʻau lapaʻau ma ka hiki ʻana i ka hoʻololi ʻana o nā molekala lāʻau lapaʻau e hoʻonui i ka pono a hoʻemi i ka metabolic susceptibility. Nā Kemika Kūikawā: Loaʻa ka hoʻohana ʻana o EDA i ka hana ʻana o nā kemika kūikawā e like me nā surfactants, plasticizers, a me nā mea waena paʻakikī i hoʻohana ʻia i ka synthesis o nā agrochemicals a me nā kemika maikaʻi. ʻO kona versatility i nā hoʻololi kemika e lilo ia i mea waiwai i nā formulations kahi e pono ai ka mana pololei ma luna o ke ʻano molekala a me ka hana. Synthesis Hoʻohui ʻia ka Ethyl difluoroacetate ma o ka hopena esterification o ka difluoroacetic acid me ka ethanol. Pili kēia kaʻina hana i ka condensation o ka difluoroacetic acid me ka ethanol ma lalo o nā kūlana i kāohi ʻia e hana i ka EDA. Hoʻoulu pinepine ʻia ka hopena e nā waikawa a i ʻole nā ​​​​​​kumu e hoʻomaʻamaʻa i ka hoʻokumu ʻana o ka pilina ester. Hoʻohana ʻia nā ʻano hoʻomaʻemaʻe e like me ka distillation a i ʻole ka solvent extraction e loaʻa ai ka EDA i ka maʻemaʻe kiʻekiʻe e kūpono no nā noi ʻoihana. ʻO ke ala synthesis pololei a me ka loaʻa ʻana o nā mea maka e kōkua i kona kumukūʻai kūpono a me ka hoʻohana ākea ʻana i ka noiʻi kula a me nā kaʻina hana ʻoihana. I ka hōʻuluʻulu manaʻo, ʻo ka ethyl difluoroacetate kahi hui versatile me nā noi koʻikoʻi i ka synthesis organik, kemika lāʻau lapaʻau, a me ka hana ʻana i nā kemika kūikawā. ʻO kona mau waiwai kemika kū hoʻokahi, me ke kūpaʻa, ka reactivity, a me ka maʻalahi o ka synthesis, e kōkua i kona koʻikoʻi i ka hoʻolaha ʻana i nā ʻenehana ma nā ʻāpana ʻoihana like ʻole a me nā aʻo ʻepekema.
