Tetrabutylammonium iodide (TBAI)waxa uu u soo baxay in uu fure u noqdo qaybaha kala duwan ee kimistariga, laga soo bilaabo catalysis ilaa cilmiga maadiga ah.Maqaalkan blog-ka ah, waxa aanu ku dhex galnay codsiyada kala duwan ee TBAI, anagoo sahameynayna doorkeeda kataliyaha ee isbeddelada dabiiciga ah iyo ka qayb qaadashada horumarinta agabka cusub.Nagu soo biir markaan daah furayno kala duwanaanshaha gaarka ah ee xaruntan xiisaha leh.
Tetrabutylammonium iodide, oo leh qaacidada kiimikada (C4H9) 4NI, waa milix afargeesle ah oo ammonium ah oo caadi ahaan loo isticmaalo horudhac isku-darka isku-dhafka dabiiciga ah.Waa adage aan midab lahayn ama caddaan ah oo aad ugu milmaya dareeraha dabaysha sida biyaha iyo alkolada.TBAI waxay leedahay codsiyo kala duwan oo kala duwan, kala duwanaanshaheedana waxay ka timaadaa awoodda ay u leedahay inay u dhaqmaan sidii kicin fal-celin kiimikaad oo kala duwan.
Mid ka mid ah codsiyada caanka ah ee TBAI waa adeegsigeeda sidii kicinta wareejinta wejiga ee isbeddellada dabiiciga ah.Catalysis-ka wareejinta wejiga (PTC) waa farsamo sahlaysa wareejinta fal-celiyeyaasha inta u dhaxaysa wejiyada aan la kala fogayn, sida wejiyada organic iyo aqueous.TBAI, oo ah kicinta wareejinta wejiga, waxay gacan ka geysataa kordhinta heerka falcelinta oo ay wanaajiso wax-soo-saarka alaabada la rabo.Waxay kor u qaadaysaa falcelinta sida beddelka nucleophilic, alkylations, iyo dehydrohalogenations, taas oo u oggolaanaysa isku-darka maaddooyinka organic adag ee waxtarka sare leh.
Catalysis-ka ka sokow, TBAI waxay sidoo kale ka heshay codsiyada sayniska maadiga ah.Waxaa loo isticmaali karaa qaab-dhismeedka ama wakiilka hab-dhismeed hagaya isku-dhafka walxaha cusub.Tusaale ahaan, TBAI waxaa lagu shaqaaleysiiyay diyaarinta noocyo kala duwan oo zeolites ah, kuwaas oo ah walxo dalool ah oo leh qaabab si fiican loo qeexay.Iyadoo la xakameynayo xaaladaha falcelinta, TBAI waxay hagi kartaa kobaca kiristaalo zeolite, taasoo horseedaysa samaynta qalab leh sifooyin la rabo sida aagga sare ee sare, cabbirka daloolka kontoroolka, iyo xasilloonida kuleylka.
Intaa waxa dheer, TBAI waxa loo adeegsaday samaynta agabka isku-dhafan, halkaas oo ay u shaqeyso sidii isku xidhaha ama xasiliye u dhexeeya qaybo kala duwan.Qalabkan isku-dhafan ayaa inta badan soo bandhiga farsamooyinka farsamada, indhaha, ama korantada oo la xoojiyey marka loo eego qaybahooda gaarka ah.TBAI waxay samayn kartaa xidhidh isuduwidda xooggan oo leh ion bir ah ama qaybo kale oo organic ah, taas oo u oggolaanaysa isku-dubarid agabyo leh hawlo ku habboon.Qalabkani waxay leeyihiin codsiyo suurtagal ah meelaha sida dareemayaasha, kaydinta tamarta, iyo kicinta.
Kala-duwanaanshaha TBAI way dhaafsiisan tahay codsiyadeeda tooska ah ee catalysis iyo sayniska maadiga.Waxa kale oo loo istcimaalay sidii korantada taageerta ee nidaamyada korantada, sida dareeraha falcelinta organic, iyo sida wakiilka doping ee isku dhafka polymers-ka.Hantideeda gaarka ah, sida milanka sare, viscosity hoose, iyo conductivity ion wanaagsan, waxay ka dhigaysaa doorasho ku haboon codsiyadan kala duwan.
Gabagabadii,Tetrabutylammonium iodide (TBAI)waa iskudhis helay waxtarka cajiibka ah ee dhinacyada catalysis iyo cilmiga maadiga.Awooddeeda in ay u dhaqmaan sidii kicinta isbeddellada organic iyo ka qayb qaadashada horumarinta alaabta cusub ayaa ka dhigaysa qalab qiimo leh oo loogu talagalay farmashiyeyaasha iyo saynisyahannada qalabka si isku mid ah.Iyadoo cilmi-baarayaashu ay sii wadaan sahaminta awoodda TBAI, waxaan filan karnaa inaan aragno horumar dheeraad ah oo ku saabsan qaybaha kala duwan ee kimistariga iyo sayniska alaabta.
