Ko te Tetrabutylammonium iodide, e mohiotia ana ko TBAI, he reagent e whakamahia whanuitia ana i roto i nga momo tauhohenga matū.Ko tetahi o nga tono tino pai me te ako whanui mo te TBAI ko tana whakamahinga ki te whakahiato azides.Engari he aha te tikanga kei muri i tenei whakautu, me pehea te whai waahi a TBAI?

 

He tino uaua te tikanga whakautu a TBAI, he maha nga waahanga matua.I te nuinga o te waa, ko tenei tauhohenga ka uru ki te reanga in situ o te hypoiodite mai i te TBAI me tetahi tauhohenga e mohiotia ana ko TBHP.Ka tauhohe tenei hypoiodite ki te puhui waro ki te hanga i tetahi takawaenga ko te azide.Ka mutu, ka whakahou ano te hypoiodite ma te waiora.

Ko te taahiraa tuatahi i roto i te tikanga tauhohenga ko te whakatipuranga o te hypoiodite mai i te TBAI me te TBHP.He mahi tino nui tenei na te mea ka timata i te tauhohenga ma te whakarato i nga momo iodine e tika ana mo te waroora o muri.He tino tauhohenga te Hypoiodate me te kaha ki te whakatairanga i te maha o nga tauhohenga matū rereke, tae atu ki te halogenation me te waikura.

Ka hangahia te hypoiodite, ka tauhohe ki te puhui waro hei hanga i te takawaenga.Ko tenei takawaenga ka whakakorehia ma te whakamahi i te reagent imide, ka taapirihia nga ngota hauota e rua ki te ngota ngota me te "whakahohe" mo etahi atu tauhohenga.I tenei wa, kua whakatutukihia e te TBAI tana kaupapa, kaore e hiahiatia ana i roto i te tauhohenga.

 

Ko te taahiraa whakamutunga i roto i te tikanga ko te whakahou i te hypoiodite.Ka tutuki tenei ma te waioratanga ma te whakamahi i nga tauhohenga tahi penei i te hydrogen peroxide.Ko te whakahou i te hypoiodite he mea tino nui na te mea ka taea e te tauhohenga te haere tonu te paihikara me te whakaputa i etahi atu azides.

I te katoa, he tino huatau, he pai hoki te tikanga whakautu a TBAI.Ma te whakaputa i te hypoiodite i roto i te waahi me te whakamahi ki te whakapouri i nga pūhui waro, ka taea e TBAI te whakatipu azides ka uaua, ka kore ranei e taea te whakahiato.Ahakoa he tohunga kemu koe e mahi ana i roto i te taiwhanga rangahau, he kaihanga ranei e rapu ana ki te whakaputa rauemi hou, he maha nga taonga a TBAI.Whakamātauria i tēnei rā!
