Trifluoromethanesulfonic anhydride CAS:358-23-6

N-Trifluoromethanesulfonic anhydride (Tf2O) inoratidzwa nemaumbirwo ayo emamorekuru, ine mapoka maviri etrifluoromethanesulfonyl (-CF3SO2) akabatana neatomu yeokisijeni. Kugadziriswa uku kunoita kuti Tf2O iite reactivity uye kugadzikana, zvichiita kuti ive reagent inofarirwa mukuchinja kwakaoma kwekugadzira. Tf2O inowanzo shandiswa semvura yakajeka, isina ruvara ine poindi yakawanda yekufashaira uye inoratidza kunyungudika kwakasimba muzvinhu zvinonyungudutsa zvakaita sedichloromethane nechloroform. Kugadzikana kwayo mumamiriro akasiyana-siyana, pamwe chete neacidity yayo ine simba, inowedzera kushanda kwayo mukugadzirwa kwakaoma kweorganic kunoda kutonga kwakaringana pamusoro pemamiriro ekuita. Mashandisirwo eOrganic Synthesis: Tf2O inoshanda sereagent inoshanda zvakasiyana-siyana mukugadzirwa kweorganic, kunyanya mukuita kunoda kushanda kwakasimba kweelectrophilic. Inowanzo shandiswa mu acylation yealcohols, amines, uye phenols kugadzira esters, amides, uye sulfonamides, zvichiteerana. Kugona uku kwakakosha pakugadzirwa kwemishonga yepakati, agrochemicals, uye zvinhu zvepamusoro zvine hunhu hwakagadzirirwa. Kemikari yePolymer: Mumaitiro epolymerization, Tf2O inobatsira kushandurwa kwemacheni epolymer kuburikidza nekuita kwesulfonation, kuvandudza kunyungudika kwepolymer, kugadzikana, uye mashandiro. Kugona kwayo kuunza mapoka esulfonic acid kunowedzera mashandiro epolymer mumashandisirwo akasiyana-siyana emaindasitiri, kusanganisira machira, mamembrane, uye maion exchange resins. Makemikari Akanaka: Tf2O inowana kushandiswa mukugadzirwa kwemakemikari akanaka akadai sedhayi, mishonga yepakati, uye ma reagents akakosha. Kugadziriswa kwayo kwekusarudza kunoita kuti mamorekuru eorganic ashande nemazvo, zvakakosha pakusimudzira basa rezvebhayoloji uye kugadzikana kwemakemikari muzvigadzirwa zvekupedzisira. Kugadzirwa kweTrifluoromethanesulfonic anhydride inogadzirwa kuburikidza nekuita kwetrifluoromethanesulfonic acid (TfOH) neacetic anhydride. Maitiro aya anosanganisira kuwedzerwa kweacetic anhydride kuTfOH pasi pemamiriro emvura, zvichitungamira pakuumbwa kweTf2O neacetic acid sechinhu chimwe. Kuita uku kunowanzo da kutarisirwa kwekupisa nekungwarira uye mhepo isina kusimba kudzivirira maitiro asina kufanira uye kuve nechokwadi chekuti Tf2O inobereka zvakawanda. Nzira dzekuchenesa dzakadai sekudistilla kana kubvisa solvent dzinoshandiswa kuparadzanisa Tf2O yakachena kwazvo yakakodzera kushandiswa mumaindasitiri. Muchidimbu, trifluoromethanesulfonic anhydride isimba rinoshandiswa zvakanyanya mukugadzirwa kwezvinhu zvakasikwa, polymer chemistry, uye kugadzirwa kwemakemikari akanaka. Kushanda kwayo nesimba, kugadzikana, uye kugona kwayo kusarudza mashandiro kunoita kuti ive yakakosha mukusimudzira matekinoroji muzvikamu zvakasiyana-siyana zvemaindasitiri nesainzi. Kugadzirwa kwakadzorwa uye kushandiswa kwakarurama kweTf2O kunobatsira zvikuru mukuvandudzwa kwezvinhu zvitsva uye makemikari ane mashandiro akawedzerwa uye mashandiro.
