1,3-Difluoroacetone CAS:453-14-5

ʻO 1,3-Difluoroacetone (DFA) kahi hui like ʻole me nā waiwai kemika kū hoʻokahi e lilo ai i mea waiwai nui i nā noi ʻoihana like ʻole. ʻO nā waiwai 1,3-Difluoroacetone i hōʻike ʻia e kona ʻano molekala, nona kahi hui ketone (-C (=O)-) i pani ʻia me ʻelua mau ʻātoma fluorine. Hāʻawi kēia hiʻohiʻona hoʻonohonoho i ka reactivity koʻikoʻi a me ke kūpaʻa i ka hui, e hoʻohuli ana i kāna mau noi i ka synthesis organik a me nā hopena kemika. Loaʻa pinepine ʻo DFA ma ke ʻano he wai volatile me kahi kiko paila a puni 80 ° C a hōʻike i ka solubility kaulike i nā solvents polar e like me ka wai a me ka acetone. ʻO kona kūpaʻa kemika ma lalo o nā kūlana akahai e kūpono ia no ka hoʻohana ʻana ma ke ʻano he poloka hale i ka synthesis o nā molekala organik paʻakikī. Hoʻohana Organic Synthesis: ʻO kekahi o nā noi mua o 1,3-difluoroacetone aia i ka synthesis organik, kahi e lawelawe ai ma ke ʻano he waena waena a i ʻole precursor. ʻO kāna hui ketone reactive e ʻae i ka hoʻokomo ʻana o nā ʻātoma fluorine i loko o nā molekala organik, e hoʻomaʻamaʻa ana i ka synthesis o nā lāʻau lapaʻau, nā agrochemicals, a me nā kemika kūikawā me nā hana fluorinated i makemake ʻia. ʻO ka Reagent Kemika: Hoʻohana ʻia ʻo DFA ma ke ʻano he reagent kemika i nā kaʻina hana hoʻokolohua a me nā ʻoihana like ʻole, me ka hoʻololi ʻana o nā biomolecules a me ka hana ʻana o nā pūhui fluorinated. ʻO kona hiki ke hana i ka hoʻololi nucleophilic a me nā hopena condensation e hoʻonui i kona pono i nā hoʻololi kemika like ʻole. ʻEpekema Mea: I ka ʻepekema mea, loaʻa iā DFA nā noi i ka hoʻomohala ʻana i nā mea kūikawā a me nā uhi. ʻO kona reactivity a me ka hiki ke hoʻohuli i nā waiwai o ka ʻili e kūpono ia no ka hoʻololi ʻana i nā ʻili mea e hoʻonui i ka lōʻihi, ke kū'ē kemika, a me ka hana ma lalo o nā kūlana kaiapuni kikoʻī. Hiki ke synthesized ʻia ka Synthesis 1,3-Difluoroacetone e ka fluorinating acetone ma lalo o nā kūlana i kāohi ʻia me ka hoʻohana ʻana i nā mea fluorinating e like me ka hydrogen fluoride (HF) a i ʻole elemental fluorine (F2). Hoʻololi ke kaʻina hana fluorination i nā ʻātoma hydrogen i loko o ka acetone me nā ʻātoma fluorine, e loaʻa ana ka 1,3-difluoroacetone ma ke ʻano he huahana nui. ʻO nā ʻano hoʻomaʻemaʻe e pili pinepine i ka distillation a i ʻole ka solvent extraction e loaʻa ai ka DFA i ka maʻemaʻe kiʻekiʻe e kūpono no nā noi ʻoihana a me ka hale hana. I ka hōʻuluʻulu ʻana, ʻo 1,3-difluoroacetone kahi pūhui versatile me nā noi koʻikoʻi i ka synthesis organik, ka reactivity kemika, a me ka ʻepekema mea. ʻO kona mau waiwai kūikawā e like me ke ketone fluorinated e hiki ai i nā hana like ʻole, e kākoʻo ana i nā holomua ma nā ʻāpana ʻoihana like ʻole a me ke kōkua ʻana i ka hoʻomohala ʻana i nā kemika a me nā mea hana kūikawā.
