N-methyl-2,2,2-trifluoroacetamide CAS:815-06-5

Ko te N-Methyl-2,2,2-trifluoroacetamide (NMTFA) e tohuhia ana e tōna hanganga ngota, kei roto ko te rōpū trifluoromethyl (-CF3) e piri ana ki te tuara acetamide (-CONHCH3). Mā tēnei hanganga ka nui te pumau me te tauhohenga ki te NMTFA, ka pai mō te whānuitanga o ngā tono matū. Ko te NMTFA te nuinga o te wā he totoka tioata me te ira rewa o te 62°C, ā, he pai te wairewa i roto i ngā whakarewa waro pōro pērā i te acetone me te etanoru. Ko tōna pumau i raro i ngā āhuatanga rerekē ka taea te whakamahi whai hua i roto i ngā rangahau taiwhanga me ngā tukanga ahumahi. Ngā Whakamahinga Hanganga Waro: Ko te NMTFA he takawaenga nui i roto i te hanga waro, inā koa i roto i te whakaurunga o ngā rōpū trifluoromethyl ki roto i ngā ngota waro. He mea nui tēnei āheinga mō te whakawhanake i ngā rongoā, ngā matū ahuwhenua, me ngā matū motuhake me te kaha koiora me te pumau matū kua whakarei ake. Matū Rongoā: I roto i ngā tono rongoā, ka whakamahia te NMTFA hei matū mua i roto i te hanga o ngā kai rongoā hohe (API) nā tōna kaha ki te whakarato i ngā āhuatanga rongoā e hiahiatia ana. He mahi nui tāna i roto i te matū rongoā mā te whakahohe i te whakarerekētanga o ngā ngota rongoā hei whakarei ake i te whai huatanga me te whakaiti i te ngoikore o te pākia. Ngā Matū Motuhake: Ka kitea te whakamahinga o te NMTFA i roto i te hanga o ngā matū motuhake pēnei i ngā surfactants, ngā plasticizers, me ngā takawaenga matatini e whakamahia ana i roto i te hanganga o ngā matū ahuwhenua me ngā matū pai. Nā tōna whānuitanga ki ngā huringa matū ka whai hua i roto i ngā whakatakotoranga e hiahiatia ana te mana whakahaere tika mō te hanganga me te mahi ngota. Ka hangaia te Hanganga N-Methyl-2,2,2-trifluoroacetamide mā te tauhohenga o te waikawa trifluoroacetic me te methylamine. Kei roto i tēnei tukanga te whakakotahitanga o te waikawa trifluoroacetic me te methylamine i raro i ngā tikanga whakahaere hei hanga NMTFA. I te nuinga o te wā ka puta te tauhohenga i te aroaro o tētahi whakakorikori e tika ana hei whakahaere i te hanganga here amide. Ka whakamahia ngā tikanga purenga pēnei i te recrystallization, te chromatography rānei hei whiwhi i te NMTFA i roto i te parakore teitei e tika ana mō ngā tono ahumahi. Ko te huarahi hanga māmā me te wātea o ngā rauemi mata e whai wāhi ana ki tōna whai huatanga utu me te whakamahinga whānui i roto i te rangahau mātauranga me ngā tukanga ahumahi. Hei whakarāpopototanga, he matū maha ngā whakamahinga o te N-methyl-2,2,2-trifluoroacetamide, ā, he nui ngā whakamahinga i roto i te hanga matū waro, te matū rongoā, me te hanga matū motuhake. Ko ōna āhuatanga matū ahurei, tae atu ki te pumau, te tauhohenga, me te ngāwari o te hanga, e whai wāhi ana ki tōna hiranga ki te whakatairanga i ngā hangarau puta noa i ngā rāngai ahumahi me ngā kaupapa pūtaiao rerekē.
