etil difluoroacetate CAS:454-31-9

Ko te Ethyl difluoroacetate (EDA) e tohuhia ana e tōna hanganga ngota, kei roto ko te rōpū difluoromethyl (-CF2COOEt) e hono ana ki te wāhanga ethyl ester. Ka whakawhiwhia e tēnei hanganga te pumau me te kaha ki te EDA, ka pai mō te whānuitanga o ngā tauhohenga matū me ngā tono. Ko te EDA he wai mārama, kore tae me te ira kohua tata ki te 100°C, ā, he pai te wairewa i roto i ngā whakarewa waro pērā i te acetone me te ethyl acetate. Nā 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: He poraka hanga nui te EDA i roto i te hanga waro, inā koa i roto i te whakaurunga o ngā rōpū difluoromethyl ki roto i ngā ngota waro. He mea nui tēnei kaha 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 EDA hei matū mua i roto i te hanga o ngā kai rongoā hohe (API) nā tōna kaha ki te tuku 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. Matū Motuhake: Ka whakamahia te EDA i roto i te hanga matū motuhake pēnei i ngā surfactants, ngā plasticizers, me ngā takawaenga matatini e whakamahia ana i roto i te hanga 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 ngota me te mahi. Te Hanga Ka hangaia te Ethyl difluoroacetate mā te tauhohenga esterification o te waikawa difluoroacetic me te etanoru. Kei roto i tēnei tukanga te whakakotahitanga o te waikawa difluoroacetic me te etanoru i raro i ngā tikanga whakahaere hei hanga EDA. Ko te tauhohenga ka whakakorikoria e ngā waikawa, e ngā turanga rānei hei whakahaere i te hanganga here ester. Ka whakamahia ngā tikanga purenga pēnei i te distillation, te tango whakarewa rānei hei whiwhi EDA i te parakore teitei e tika ana mō ngā tono ahumahi. Ko te huarahi hanga māmā me te wātea o ngā rauemi mata ka whai wāhi ki tōna whai huatanga utu me te whakamahinga whānui i roto i te rangahau mātauranga me ngā tukanga ahumahi. Hei whakarāpopototanga, he matū maha-whakamahinga te ethyl difluoroacetate me ngā tono nui i roto i te hanga rauropi, 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, ka whai wāhi ki tōna hiranga ki te whakatairanga i ngā hangarau puta noa i ngā rāngai ahumahi me ngā kaupapa pūtaiao.
