Ko te Tetra-n-butylammonium bromide (TBAB) hetote ammonia whā-whāhe ranunga me ngā tono e kapi ana i ngā mara maha:
1. Te hanga rauropi
TBABe whakamahia pinepine ana heiwhakakorikori whakawhiti ā-wāhangahei whakatairanga i te whakawhiti me te whakawhiti o ngā matū tauhohe i roto i ngā pūnaha tauhohenga rua-wāhanga (pērā i ngā wāhanga waiora), pērā i ngā tauhohenga whakakapinga nucleophilic, te whakarite hauwaiwaro halogenated, te etherification, me ngā tauhohenga esterification, ka taea te whakanui ake i te hua me te whakapoto i te wā tauhohenga.

2. Matūhiko Hiko
E whakamahia ana i roto i te mara o te hanga pākahiko, hei tāpiringa irahiko, ka taea te whakarei ake i te mahi hikohiko, inā koa i roto i te rangahau o ngā pākahiko lithium-ion, e whakaatu ana i ngā tono pea.
3. Te hanga rongoā
Nā ōna āhuatanga patu huakita he rauemi matua mō te hanga rongoā patu huakita, me te whakahohe hoki i ngā mahi matua o te hanga rongoā pērā i te hanganga o ngā here waro hauota me te waro hāora.
4. Te tiaki i te taiao
Whakamahia i roto i ngā horopaki maimoatanga wai mā te pānga tukunga puhoi o ngā katote konganuku taumaha, hei tango, hei whakaora rānei i ngā poke konganuku taumaha i roto i ngā wai.
5. Te whakaputa matū
Whakamahia i roto i te mara o ngā matū pai mō te hanga tae, kakara, me ngā rauemi polymer, me te whai wāhi ki te alkylation, te acylation, me ētahi atu tauhohenga.
