AMMONIUM TRIFLUOROACETATE CAS: 3336-58-1

Ammonium trifluoroacetate (ATA) yog ib qho tshuaj sib xyaw ua ke uas muaj cov khoom siv tshuaj sib txawv uas ua rau nws tseem ceeb hauv ntau yam kev siv hauv kev lag luam. Cov Khoom ATA yog tus cwj pwm los ntawm nws cov qauv molecular, suav nrog ammonium cation (NH4 +) thiab trifluoroacetate anion (CF3COO-). Qhov kev sib xyaw ua ke no ua rau cov khoom siv crystalline uas yaj tau hauv dej nrog kev ruaj khov siab nyob rau hauv cov xwm txheej ib txwm muaj. ATA qhia txog kev hloov pauv tsawg thiab kev yaj siab hauv cov kuab tshuaj polar xws li dej thiab acetone, ua rau nws tsim nyog rau cov ntawv thov uas tswj kev tso tawm lossis kev yaj yog qhov zoo. Nws cov tshuaj ruaj khov thiab tsis xeb pab txhawb rau nws txoj kev tuav thiab siv kev nyab xeeb hauv ntau yam txheej txheem tshuaj. Siv Organic Synthesis: ATA ua haujlwm ua tus neeg ua ntej ntau yam hauv kev tsim cov organic, pab txhawb kev qhia txog trifluoromethyl pawg rau hauv cov organic molecules. Lub peev xwm no yog qhov tseem ceeb hauv kev tshuaj lom neeg rau kev tsim cov tshuaj fluorinated nrog kev ua haujlwm zoo dua thiab hauv cov ntaub ntawv tshawb fawb rau kev hloov kho cov khoom nto thiab txhim kho cov khoom siv ruaj khov. Catalyst: ATA ua haujlwm ua tus catalyst hauv ntau yam tshuaj tiv thaiv, tshwj xeeb tshaj yog cov uas muaj cov txheej txheem esterification thiab amidation. Ua ib qho catalyst precursor, ATA txhim kho kev ua haujlwm ntawm cov tshuaj tiv thaiv thiab kev xaiv, ua rau nws muaj txiaj ntsig zoo hauv kev tsim tshuaj lom neeg hauv kev lag luam thiab kev tshawb fawb hauv chaw kuaj mob. Cov khoom ntxiv hauv Cov Txheej Txheem Kev Lag Luam: ATA yog siv ua ib qho khoom ntxiv hauv cov txheej txheem kev lag luam xws li electroplating thiab kev kho saum npoo hlau, qhov twg nws lub peev xwm los tsim cov khoom sib xyaw ruaj khov nrog cov hlau ions txhim kho cov txheej txheem ua haujlwm zoo thiab cov khoom zoo. Nws kuj pom daim ntawv thov hauv kev zas xim textiles thiab hauv kev tsim cov tshuaj tshwj xeeb vim nws sib xws nrog ntau yam tshuaj lom neeg. Kev Tsim Khoom Ammonium trifluoroacetate yog tsim los ntawm kev ua kom tsis muaj zog trifluoroacetic acid (CF3COOH) nrog ammonium hydroxide (NH4OH) nyob rau hauv cov xwm txheej tswj hwm. Cov tshuaj tiv thaiv ua rau ATA ua cov khoom siv crystalline uas yaj tau hauv dej, uas tuaj yeem ua kom huv los ntawm recrystallization kom ua tiav qhov huv siab uas haum rau kev siv hauv kev lag luam. Cov txheej txheem tsim khoom yooj yim thiab kev muaj cov khoom siv raw pab txhawb rau nws cov nqi tsim nyog thiab kev siv dav dav thoob plaws ntau yam kev lag luam. Hauv kev xaus, ammonium trifluoroacetate yog ib qho tshuaj sib xyaw ua ke nrog cov ntawv thov tseem ceeb hauv kev tsim cov organic, catalysis, thiab cov txheej txheem kev lag luam. Nws cov khoom siv tshuaj lom neeg tshwj xeeb thiab qhov ruaj khov ua rau nws tseem ceeb rau kev txhim kho cov tshuaj tiv thaiv, hloov kho cov khoom siv, thiab txhim kho cov thev naus laus zis tshiab thoob plaws ntau yam kev lag luam thiab kev tshawb fawb.
