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

He matū maha ngā mahi a te 1,3-Difluoroacetone (DFA) me ōna āhuatanga matū ahurei e whai hua ai i roto i ngā tono ahumahi. Ngā Āhuatanga Ko te 1,3-Difluoroacetone e tohuhia ana e tōna hanganga ngota, kei roto ko te rōpū ketone (-C(=O)-) kua whakakapia ki ngā ngota fluorine e rua. Mā tēnei āhuatanga hanganga ka puta he tauhohenga me te pumau ki te matū, ka awe i ana tono i roto i te hanganga rauropi me ngā tauhohenga matū. Ko te DFA he wai pūngāwerewere me te ira kohua tata ki te 80°C, ā, he wairewa ngawari ki roto i ngā whakarewa porotaka pērā i te wai me te acetone. Ko tōna pumau matū i raro i ngā āhuatanga ngawari ka pai mō te whakamahi hei poraka hanga i roto i te hanganga o ngā ngota rauropi matatini. Ngā Whakamahinga Hanganga Rauropi: Ko tētahi o ngā tono matua o te 1,3-difluoroacetone kei roto i te hanganga rauropi, kei reira e mahi ana hei takawaenga matua, hei mua rānei. Mā tōna rōpū ketone tauhohenga ka taea te whakauru i ngā ngota fluorine ki roto i ngā ngota rauropi, ka whakahaere i te hanganga o ngā rongoā, ngā matū ahuwhenua, me ngā matū motuhake me ngā mahi fluorinated e hiahiatia ana. Tauhohenga Matū: Ka whakamahia te DFA hei tauhohenga matū i roto i ngā tukanga taiwhanga me ngā tukanga ahumahi, tae atu ki te whakarerekētanga o ngā ngota koiora me te hanga i ngā pūhui fluorinated. Ko tōna kaha ki te whai i ngā tauhohenga whakakapinga nucleophilic me te condensation ka whānui ake tōna whai huatanga i roto i ngā panonitanga matū rerekē. Pūtaiao Rauemi: I roto i te pūtaiao rauemi, ka kitea e te DFA ngā tono i roto i te whanaketanga o ngā rauemi me ngā paninga motuhake. Ko tōna tauhohenga me tōna kaha ki te awe i ngā āhuatanga o te mata e pai ai mō te whakarerekē i ngā mata rauemi hei whakarei ake i te roa, te ātete matū, me te mahi i raro i ngā āhuatanga taiao motuhake. Ka taea te hanga i te 1,3-Difluoroacetone mā te fluorinating acetone i raro i ngā āhuatanga whakahaeretia mā te whakamahi i ngā kaihoko fluorinating pērā i te hauwai fluoride (HF) te fluorine huānga rānei (F2). Ka whakakapia e te tukanga fluorination ngā ngota hauwai i roto i te acetone ki ngā ngota fluorine, ka puta ko te 1,3-difluoroacetone hei hua matua. Ko ngā tikanga purenga ko te whakakorenga, te tango whakarewa rānei hei whiwhi i te DFA i roto i te parakore teitei e tika ana mō ngā tono ahumahi me te taiwhanga. Hei whakarāpopototanga, he pūhui maha ngā mahi a te 1,3-difluoroacetone me ngā tono nui i roto i te hanga rauropi, te tauhohenga matū, me te pūtaiao rauemi. Mā ōna āhuatanga ahurei hei ketone fluorinated ka taea te whakamahi i ngā mahi rerekē, hei tautoko i ngā whanaketanga i roto i ngā momo rāngai ahumahi, me te whai wāhi ki te whanaketanga o ngā matū me ngā rauemi motuhake.
