Tetrabutylammonium iodide, kuma aka sani da TBAI, reagent ne da ake amfani da shi sosai a cikin halayen sinadarai daban-daban.Ɗaya daga cikin mafi ban sha'awa da kuma nazarin aikace-aikacen TBAI shine amfani da ita a cikin haɗin azides.Amma menene tsarin da ke bayan wannan martani, kuma ta yaya TBAI ke ba da gudummawar ta?
Hanyar mayar da martani na TBAI yana da rikitarwa kuma ya ƙunshi matakai da yawa.Gabaɗaya, wannan matakin ya haɗa da samar da hypoiodite a wurin daga TBAI da kuma mai haɗin gwiwa da aka sani da TBHP.Wannan hypoiodite sannan yana amsawa tare da fili na carbonyl don samar da matsakaici wanda daga baya azide.A ƙarshe, an sake haɓaka hypoiodite ta hanyar oxidation.
Mataki na farko a cikin tsarin amsawa ya ƙunshi haɓakar hypoiodite daga TBAI da TBHP.Wannan mataki ne mai mahimmanci saboda yana fara amsawa ta hanyar samar da nau'in aidin da ake bukata don carbonyl oxidation na gaba.Hypoiodate yana maida martani sosai kuma yana da ikon haɓaka halayen sinadarai daban-daban, gami da halogenation da oxidation.
Da zarar an kafa hypoiodite, yana amsawa tare da fili na carbonyl don samar da matsakaici.Wannan tsaka-tsakin kuma ana azidated ta amfani da imide reagent, wanda ke ƙara atom ɗin nitrogen guda biyu zuwa kwayoyin halitta kuma da gaske "yana kunna" don ƙarin halayen.A wannan lokacin, TBAI ta cika manufarta kuma ba a buƙatar ta a cikin martani.
Mataki na ƙarshe a cikin injin ya haɗa da farfadowa na hypoiodite.Ana samun wannan ta hanyar hadawan abu da iskar shaka ta amfani da masu haɗakarwa kamar hydrogen peroxide.Sake farfado da hypoiodite yana da mahimmanci saboda yana ba da damar amsawa don ci gaba da hawan keke da kuma samar da ƙarin azides.
Gabaɗaya, tsarin amsawar TBAI yana da kyau da inganci.Ta hanyar samar da hypoiodite a wurin da amfani da shi don oxidize mahadi na carbonyl, TBAI yana ba da damar samar da azides waɗanda in ba haka ba zai yi wahala ko ba zai yiwu a haɗa su ba.Ko kai masanin kimiyya ne da ke aiki a dakin gwaje-gwajen bincike ko masana'anta da ke neman samar da kayan labari, TBAI tana da abubuwa da yawa don bayarwa.Gwada shi a yau!
