Trifluoromethanesulfonic anhydride CAS:358-23-6

N-Trifluoromethanesulfonic anhydride (Tf2O) waxaa lagu gartaa qaab-dhismeedkeeda molecular, oo leh laba kooxood oo trifluoromethanesulfonyl (-CF3SO2) ah oo ku xiran atamka oksijiinta. Qaab-dhismeedkani wuxuu siinayaa Tf2O falgal iyo xasillooni gaar ah, taasoo ka dhigaysa falgal la doorbidayo isbeddellada isku-dhafka ah ee adag. Tf2O waxaa badanaa loo maareeyaa sidii dareere cad, midab la'aan ah oo leh dhibic karkaraya oo sare waxayna muujisaa milmi xooggan oo ku jira dareerayaasha dabiiciga ah sida dichloromethane iyo chloroform. Xasilloonideeda xaalado kala duwan, oo ay weheliso aashitada awoodda badan, waxay kor u qaadaysaa faa'iiddeeda isku-dhafka dabiiciga ah ee adag oo u baahan xakameyn sax ah oo ku saabsan xaaladaha falcelinta. Isticmaalka Isku-darka Dabiiciga ah: Tf2O waxay u adeegtaa sidii falgal kala duwan oo ku jira isku-darka dabiiciga ah, gaar ahaan falcelinta u baahan firfircooni koronto oo xooggan. Waxaa si caadi ah loogu isticmaalaa isku-darka alkolada, amines, iyo phenols si loo sameeyo esters, amides, iyo sulfonamides, siday u kala horreeyaan. Awooddani waa mid muhiim u ah horumarinta dhexdhexaadiyeyaasha dawooyinka, kiimikooyinka beeraha, iyo agabyada horumarsan ee leh sifooyin gaar ah. Kiimikada Polymer-ka: Hawsha polymerization-ka, Tf2O waxay sahlaysaa wax ka beddelka silsiladaha polymer-ka iyada oo loo marayo falgallada sulfonation-ka, iyadoo hagaajinaysa milmida polymer-ka, xasilloonida, iyo shaqeynta. Awooddeeda ay ku soo bandhigto kooxaha aashitada sulfonic waxay kor u qaaddaa waxqabadka polymer-ka ee codsiyada warshadaha kala duwan, oo ay ku jiraan dahaarka, xuubka, iyo resins-ka is-weydaarsiga ion-ka. Kiimikooyinka Fiican: Tf2O waxay ku heshaa codsi isku-darka kiimikooyinka fiican sida midabyada, dhexdhexaadiyeyaasha daawada, iyo reagents-ka gaarka ah. Falgalkeeda xulashada ah wuxuu suurtogal ka dhigayaa shaqeynta saxda ah ee molecules-ka dabiiciga ah, oo muhiim u ah kor u qaadista dhaqdhaqaaqa bayoolojiga iyo xasilloonida kiimikada ee alaabada ugu dambeysa. Isku-darka Trifluoromethanesulfonic anhydride waxaa lagu sameeyaa falcelinta trifluoromethanesulfonic acid (TfOH) oo leh acetic anhydride. Hawshani waxay ku lug leedahay ku darista la xakameeyey ee acetic anhydride TfOH xaaladaha aan biyaha lahayn, taasoo horseedaysa sameynta Tf2O iyo acetic acid oo ah wax soo saar ka baxsan. Falcelinta waxay caadi ahaan u baahan tahay xakamaynta heerkulka taxaddar leh iyo jawi aan firfircoonayn si looga hortago falcelinta dhinaca aan loo baahnayn iyo hubinta wax soo saar sare oo Tf2O ah. Farsamooyinka nadiifinta sida kala-soocidda ama soo saarista dareeraha ayaa loo adeegsadaa in lagu kala saaro Tf2O si nadiif ah oo heer sare ah oo ku habboon codsiyada warshadaha. Marka la soo koobo, anhydride-ka trifluoromethanesulfonic waa reagent awood badan oo si ballaaran loogu isticmaalo isku-darka dabiiciga ah, kiimikada polymer-ka, iyo soo saarista kiimikooyinka fiican. Awooddeeda fal-celinta xooggan, xasilloonida, iyo shaqeynta xulashada ah waxay ka dhigaysaa mid aan lagama maarmaan u ah horumarinta teknoolojiyada qaybaha kala duwan ee warshadaha iyo cilmiga sayniska. Isku-darka la xakameeyey iyo codsiga saxda ah ee Tf2O waxay si weyn uga qayb qaataan horumarinta agabyada iyo isku-dhafka cusub oo leh waxqabad iyo shaqo la xoojiyay.
