Calcium trifluoromethansulphonate CAS: 55120-75-7

Calcium trifluoromethanesulfonate (CF3SO3Ca) muaj lub luag haujlwm tseem ceeb hauv kev siv hauv kev lag luam vim nws cov khoom siv tshuaj lom neeg tshwj xeeb thiab kev hloov pauv tau yooj yim. Cov Khoom Calcium trifluoromethanesulfonate feem ntau pom tias yog cov khoom dawb crystalline. Nws qhia txog kev yaj tau zoo hauv cov kuab tshuaj polar xws li dej thiab acetone, thaum tsis yaj hauv cov kuab tshuaj uas tsis yog polar xws li hexane. Cov tshuaj no qhia txog hygroscopic tendencies, yooj yim nqus cov dej noo los ntawm ib puag ncig. Nws tswj kev ruaj khov thermal, khaws nws cov qauv kev ncaj ncees thoob plaws ntau qhov kub thiab txias, uas ua rau nws siv tau zoo hauv cov txheej txheem catalytic. Siv Catalysis: Ib qho kev siv tseem ceeb ntawm calcium trifluoromethanesulfonate yog catalyzing organic synthesis reactions. Ua ib qho tshuaj catalyst muaj zog, nws ua kom cov txheej txheem xws li esterifications, alkylations, thiab rearrangements los ntawm kev ua kom cov substrates zoo nyob rau hauv cov xwm txheej tsis hnyav. Lub peev xwm no yog qhov tseem ceeb hauv kev tsim cov tshuaj, agrochemicals, thiab cov tshuaj tshwj xeeb. Phase-Transfer Catalyst: Ntxiv rau nws lub luag haujlwm ua ib qho acid catalyst, calcium trifluoromethanesulfonate ua haujlwm ua ib qho phase-transfer catalyst. Nws pab txhawb kev hloov pauv ntawm cov tshuaj reactants ntawm cov theem tsis sib xyaw, feem ntau yog aqueous thiab organic, yog li txhim kho kev ua haujlwm ntawm cov tshuaj tiv thaiv thiab cov txiaj ntsig hauv ntau yam kev hloov pauv tshuaj. Cov Khoom Siv Science: Cov tshuaj no pom cov ntawv thov hauv cov khoom siv science, tshwj xeeb tshaj yog hauv kev tsim cov ntaub ntawv tshwj xeeb thiab cov txheej txheem uas nws qhov ruaj khov thiab cov khoom solubility zoo. Kev Tsim Khoom Calcium trifluoromethanesulfonate tuaj yeem tsim los ntawm kev cuam tshuam trifluoromethanesulfonic acid (CF3SO3H) nrog calcium hydroxide (Ca(OH)2). Cov txheej txheem neutralization no ua rau calcium trifluoromethanesulfonate nrog rau dej ua cov khoom seem. Cov khoom tshwm sim tuaj yeem raug ntxuav los ntawm crystallization kom ua tiav cov tshuaj purity siab rau cov ntawv thov kev lag luam. Hauv kev xaus, calcium trifluoromethanesulfonate yog cov tshuaj sib xyaw ua ke tseem ceeb hauv cov organic synthesis, catalysis, thiab cov ntaub ntawv science. Nws cov khoom sib txawv ua cov tshuaj acid catalyst thiab cov neeg sawv cev hloov pauv theem pab txhawb rau kev nce qib ntawm cov thev naus laus zis tshuaj thiab kev txhim kho cov ntaub ntawv siab heev thoob plaws ntau yam kev lag luam.
