Whakamahinga
1. Whakaterenga whakawhiti ā-wāhanga - Ko te Tetraethylammonium bromide he whakaterenga whakawhiti ā-wāhanga e whakamahia whānuitia ana i roto i ngā tauhohenga hanga waro. Hei tauira, i roto i te tauhohenga i waenga i ngā hauwaiwaro halogenated me ngā tauhohenga nucleophilic, ka taea e ia te whakatairanga i te tauhohenga. I roto i ngā tauhohenga alkylation, ina tauhohe ngā alkane halogenated ki ngā matū kei roto te hauwai hohe (pērā i ngā phenols, ngā waipiro, ngā waikawa carboxylic, me ētahi atu), ka taea e te tetraethylammonium bromide te whakaputa i te tauhohenga i raro i ngā āhuatanga ngawari. Nā te mea ka taea e ia te āwhina i ngā tauhohenga nucleophilic ki te whakawhiti mai i te ā-wai ki te ā-wāhanga waro, ka pai ai te haere o te tauhohenga i roto i te ā-wāhanga waro. Hei tauira, i roto i te tauhohenga alkylation o te phenylacetonitrile me ngā alkane halogenated, ka taea e te tetraethylammonium bromide te whakanui ake i te hua tauhohenga.
2. Kaiwhakauru chromatography takirua katote - He mahi nui tā te Tetraethylammonium bromide hei kaiwhakauru takirua katote i roto i te chromatography takirua katote. Ka taea e ia te hanga takirua katote me ngā analyte me ngā utu rerekē, ā, ka huri i te whanonga pupuri o ngā analyte. I te tātaritanga o ngā matū pēnei i ngā turanga waro, ngā waikawa waro rānei, mā te whakarerekē i te kukū o te tetraethylammonium bromide, ka taea te whakapai ake i ngā āhuatanga wehenga chromatography. Hei tauira, i te tātaritanga o ētahi alkaloids, ka taea e ia te hanga takirua katote me ngā kation alkaloid, kia tika ai te wā pupuri o ngā alkaloids i runga i te pou chromatography wāhanga-hurihuri, ā, ka pai ake te pānga wehenga.
3. Kaihoroi - Ka taea hoki te whakamahi hei kaihoroi cationic. I roto i ētahi tauhohenga polymerization emulsion, ka taea e te tetraethylammonium bromide te whakaiti i te taumahatanga mata, ā, ka taea ai e ngā monomer te horapa pai ake i roto i te pūnaha tauhohenga. Hei tauira, i roto i te polymerization emulsion o te styrene, mā te tāpiri i te nui tika o te tetraethylammonium bromide ka taea te horapa ōrite o ngā pata styrene, ka āwhina i te ahunga whakamua o te tauhohenga polymerization, ā, ka taea te whakapai ake i te pumau o te polymer emulsion.
4. Ētahi atu whakamahinga - I roto i te mara o te matū hiko, ka taea te whakamahi i te tetraethylammonium bromide hei wāhanga o ngā irahiko. I roto i ētahi pākahiko, i ētahi pūoko hiko rānei, ka taea e ia te whakarato i ngā hongere kawe katote. Hei tauira, i roto i ētahi taputapu hiko e hangai ana ki ngā kiriuhi whakawhiti katote, ka taea e te tetraethylammonium bromide te āwhina ki te pupuri i te taurite katote i ngā taha e rua o te kiriuhi, kia pai ai te mahi a te taputapu.
