IISEBE:Isigaba senqanaba eliluncedo. I-18-Crown-6 isetyenziswa njengendawo yokudluliselwa kwesigaba esisebenzayo kunye nearhente yengozi eneentlobo ngeentlobo zendlela encinci. Ibandakanyeka kwi-synthesis ye-diaryl eenye, idayary tioethers, kunye ne-searymine ibhaliswe nge-potassium flusside-alumina kunye ne-18-crown-6. Iququzelela i-smobing ye-potassium engafaniyo e-Bengne, esetyenziselwa ukunyanzelisa i-odormic complets. Isetyenziselwa ukukhawulezisa ukuphinda kwenziwe endaweni yokufakelwa okuthandwayo kunye nokwandisa amandla ee-nucleophiles ezinje nge-potassium ye-potatate. Isetyenziswa kwi-Alkysist Reactions phambi kwe-potasqundausium carbonate, n-alkyation ye-glutarimide kwaye iSuccimimaimide ene-dimthylbonate. Ubunzima obuwenziwe yindlela yayo yokusabela nge-potassium cyside isebenza njengeyona nto iphambili kwi-aldehydes, iiKenenes kunye neQuinethyllide (TMSCN). I-18-Crown-6 ingasetyenziselwa ukonakalisa i-N-Alkysity ye-H-Alkyally ye-HETEROCYCACCCILL COARDS NOMAKHONI YENKONZO YAMA-AldeHYSES.
Intshayelelo Eneenkcukacha
I-18-Crown-6Ngaba i-ether ye-cyclic ye-cyclic ye-chemic formic foula c124o6. Ibizwa ngegama "I-18-Crown-6" Ngenxa yokuba iqulethe i-omom ye-oxtom ezintandathu, yenza isakhiwo esifana nesithsaba, kwaye inee-atom ezili-18 zizonke. Yinto engenamibala, i-crystalline iqinile enyibilikayo kwiinyibilikisi zendalo kodwa ifana ne-sholline emanzini.
Igama "Isithsaba" lithathwe kwi-complay yendawo efana nesithsaba ngenxa yeeathom ezintandathu zeoksijini ezicwangciswe kwipateni ejikelezileyo. Esi sakhiwo sahlukileyo sinika i-18-Crown-6 IIPROPSE ZESIBINI ZOKUGQIBELA kwaye ziyenza ukuba isetyenziswe ngokubanzi kwizicelo ezahlukeneyo.
Enye yeempawu eziphambili ze-18-crown-6 kukwazi kwawo ukuntywila ngee-ion zentsimbi. Ii-atom zeoksijini kwi-ring ye-crown zinokulungelelanisa nee-cunt zensimbi, ezinje nge-potassium, isodium, okanye i-calcium, ukwenza izigqibo zokulungelelanisa. Le propati yenza i-18-crown-6 i-computer esetyenziswe ngokubanzi kwicandelo le-chemistry.
Isicelo
Ukuntywila kwee-ion zentsimbi nge-18-crown-6 kunokuba nezicelo ezahlukeneyo:
Inqanaba lesigaba senqanaba:Njenge-benzyltltriethriemmonium chloride, i-18-Crown-6 inakho nokusebenza njengesigaba sokudluliselwa kwesigaba. I-AIDS ekudluliseleni izidalwa ezihlawuliswayo, ezinje ngee-ion zentsimbi, phakathi kwezigaba ezingxamisekileyo, zivumela ukuba kube nzima okanye akunakwenzeka. I-Crown Other Cavity inokucacisa ii-cent zensimbi, zibavumela ukuba badlule kwi-membrane okanye ukudluliselwa phakathi kwezisombululo ezahlukeneyo.
Ukukhutshwa kwentsimbi kunye nokwahlukana:I-18-Crown-6 ihlala isetyenziswa ekuqinisekiseni iindlela zokukhuthaza ukukhetha kunye nee-ions zentsimbi ezithile ezivela kumxube onzima. Isakhono sayo sokubopha ngeengcaciso zesinyithi ezithile zivumela ukuba bodwa kunye nokucocwa kwezi-ion kumxube.
I-Iyon eyamkelweyo kunye nemvakalelo:Ukuntywila kwee-ion zentsimbi nge-18-crown-6 kunokusetyenziswa kuyilo lweenzwa zensimbi kunye nee-electrods ze-ion. Ngokufaka i-18-Crown-6 kwiinkqubo ze-insor, kunokwenzeka ukuba ukhethe kwaye ulinganise ii-ion ezithile zensimbi ngokusekwe kubumbano be-crown.
Iinkqubo zokuhambisa iziyobisi:Isakhono se-18-crown-6 ukuya kwi-FOSTESS SPROSS nge-ion yentsimbi inokusetyenziswa kwiinkqubo zokuhambisa iziyobisi. Ngokuxhobisela ii-ions zentsimbi ngaphakathi kwe-crown ye-crown ye-crown, kunokwenzeka ukukhusela ii-ion zentsimbi ngexesha lothutho kwaye ubakhulule ngendlela elawulwayo kwindawo ekugxilwe kuyo.
Lilonke, i-18-Crown-6 sisiqalo esiguquguqukayo esifumana izicelo zokudlulisela isigaba seCatalysis, i-ion yentsimbi, inkcazo yentsimbi, kunye nokuhanjiswa kweziyobisi. Isakhiwo sayo esikhethekileyo esikhethekileyo kunye neepropathi ezinzima zenza isixhobo esibalulekileyo kwiinkalo ezahlukeneyo ze-chemistry kunye nesayensi yezixhobo.
