Tetrabutylammonium iodide, oo sidoo kale loo yaqaan TBAI, waa reagen si weyn loo isticmaalo fal-celin kiimikaad oo kala duwan.Mid ka mid ah codsiyada ugu xiisaha badan ee aadka loo bartay ee TBAI waa adeegsigeeda isku dhafka azides.Laakiin waa maxay habka ka dambeeya jawaabtan, sideese TBAI uga qayb qaadataa?
Habka jawaabta TBAI waa mid aad u adag waxayna ku lug leedahay dhowr tillaabo oo muhiim ah.Guud ahaan, falcelintani waxay ku lug leedahay jiilka goobta ee hypoiodite ee ka yimaada TBAI iyo falceliye loo yaqaan TBHP.Hypoiodite-kani waxa uu markaa la falgalaa kaarboonyl ka samaysan si uu u sameeyo dhexdhexaad ka dibna azide ah.Ugu dambeyntii, hypoiodite ayaa mar kale dib loo soo nooleeyaa oksaydheynta.
Tallaabada ugu horreysa ee habka falcelinta waxay ku lug leedahay abuuritaanka hypoiodite ee TBAI iyo TBHP.Tani waa tallaabo muhiim ah sababtoo ah waxay bilawday falcelinta iyada oo siinaya noocyada iodine ee lagama maarmaanka u ah oksaydhka karbonyl ee xiga.Hypoiodate waa mid aad u firfircoon oo awood u leh inay kor u qaaddo falcelin kiimiko oo badan oo kala duwan, oo ay ku jiraan halogenation iyo oksidation.
Marka hypoiodite la sameeyo, waxay la falgashaa kaarboonyl ka samaysan si ay u samayso dhexdhexaad.Dhexdhexaadkan ayaa markaa la azidated isticmaalaya imide reagent, kaas oo ku daraya laba atamka nitrogen ee molecule oo asal ahaan "ka shaqeysiiya" falcelin dheeraad ah.Halkaa marka ay marayso, TBAI way ka soo baxday ujeeddadii loomana baahna falcelinta.
Tallaabada ugu dambeysa ee farsamadu waxay ku lug leedahay dib u soo kabashada hypoiodite.Tan waxaa lagu gaaraa oksaydheynta iyadoo la isticmaalayo fal-celiyayaal sida hydrogen peroxide.Dib-u-soo-nooleynta hypoiodite waa muhiim sababtoo ah waxay u oggolaanaysaa fal-celinta inay sii wado baaskiilka oo ay soo saarto azides badan.
Guud ahaan, habka jawaabta TBAI waa mid aad qurux badan oo hufan.Iyadoo la abuurayo hypoiodite goobta oo loo isticmaalo in lagu oksijiyo xeryahooda carbonyl, TBAI waxay awood u siinaysaa jiilka azides kuwaas oo haddii kale adkaan lahaa ama aan macquul ahayn in la isku daro.Haddii aad tahay farmashiste ka shaqeeya shaybaadhka cilmi-baadhista ama soo-saare doonaya inuu soo saaro agab cusub, TBAI waxay haysaa wax badan oo ay ku bixiso.Isku day maanta!
