Tetramethylammoniumchloride CAS:1112-67-0

Tetramethylammonium chloride (TMAC) waxay ka heshaa codsi ballaaran oo ku saabsan isku-darka dabiiciga ah sida kicinta wareejinta-wajiga, taasoo awood u siinaysa wareejinta hufan ee ion-yada u dhexeeya marxaladaha kala duwan iyo kor u qaadida falcelinta kiimikada ee kala duwan. Isku-darkani wuxuu si gaar ah qiimo ugu leeyahay hababka ku lug leh alkylation-ka nucleophiles iyo diyaarinta isku-dhafka ammonium ee quaternary, halkaas oo ay sahlayso wareejinta wakiilada alkylating inta u dhaxaysa dareerayaasha aan la missili karin, taasoo horseedaysa heerarka falcelinta oo la xoojiyay iyo wax-soo-saarka wax-soo-saarka oo la hagaajiyay. Marka laga soo tago doorkeeda kicinta wareejinta-wajiga, tetramethylammonium chloride waxaa loo isticmaalaa isku-darka tetramethylammonium hydroxide, oo ah fal-gal muhiim ah oo ku jira kiimikada dabiiciga ah. Tetramethylammonium hydroxide waxaa badanaa loo isticmaalaa saldhig xooggan oo loogu talagalay fal-celinno kala duwan, oo ay ku jiraan hababka ka-saarista iyo tirtiridda, taasoo ka dhigaysa TMAC mid muhiim u ah soo saarista kiimikadan qiimaha leh. Intaa waxaa dheer, tetramethylammonium chloride waxay u adeegtaa sidii isha cations-ka tetramethylammonium ee dareeraha ionic, kuwaas oo loo isticmaalo sidii dareere deegaanka u fiican oo ku jira habab badan oo kiimiko ah. Dareerahan ionic-ka ah waxay heleen dareen ku saabsan sifooyinkooda gaarka ah, sida isbeddel yar iyo xasillooni heerkul sare, TMAC-na waxay gacan ka geysataa isku-darka iyo codsigooda dhinacyo kala duwan oo ay ku jiraan katalisyada, kiimikada elektaroonigga ah, iyo sayniska agabka. Intaa waxaa dheer, TMAC waxaa loo isticmaalaa diyaarinta resins-ka is-weydaarsiga ion-ka, halkaas oo ay u shaqeyso sidii wakiil is-weydaarsi si loo beddelo qaab-dhismeedka iyo sifooyinka matrix-ka resin-ka, taasoo suurtogalinaysa hababka kala-soocidda iyo nadiifinta hufan ee warshadaha kala duwan. Awooddeeda ay ku soo bandhigi karto kooxaha ammonium-ka ee quarternary laf-dhabarta resin-ka waxay kor u qaadaysaa waxqabadka iyo xulashada agabkan codsiyada sida daaweynta biyaha, soo saarista dawooyinka, iyo nadiifinta kiimikada. Marka la soo koobo, tetramethylammonium chloride waxay door muhiim ah ka ciyaartaa isku-darka dabiiciga ah, katalisyada, iyo cilmi-baarista kiimikada sida katalisyada wareejinta marxaladda, horudhaca tetramethylammonium hydroxide, qayb ka mid ah dareerayaasha ionic, iyo wakiilka is-weydaarsiga ion-ka. Codsiyada kala duwan waxay gacan ka geystaan ​​​​horumarinta hababka kiimikada ee kala duwan iyo horumarinta agabyada cusub ee warshadaha badan.
