Taw qhia
Sulfur trioxide-triethylamine complex (Sulfur trioxide-triethylamine complex) yog cov organic sulfur compound. Nws cov tshuaj formula yog (C2H5)3N · SO3. Lub complex muaj cov khoom nram qab no:
1. Cov qauv kev ruaj ntseg: Lub complex yog khoom ntawm chav tsev kub thiab muaj kev ruaj ntseg zoo.
2. catalyst: lub complex feem ntau yog siv los ua ib qho catalyst rau acylation, esterification, amidation thiab lwm yam kev cuam tshuam hauv cov organic synthesis.
3. Kev ua haujlwm siab: Sulfur trioxide-triethylamine complex yog ib pab pawg neeg muaj zog sulfate, uas tuaj yeem ua rau muaj kev cuam tshuam ntau yam hauv cov organic synthesis.
4. hnyav ntawm ionic kua: Sulfur trioxide-triethylamine complex yuav siv tau raws li hnyav ntawm ionic kua nyob rau hauv ib co tshuaj, muab zoo catalytic ib puag ncig.
Txoj kev npaj ntawm lub complex yog raws li nram no:
1. Direct mixing method: ncaj qha sib tov sulfur trioxide thiab triethylamine nyob rau hauv ib tug tej yam molar piv, do thiab react nyob rau hauv ib tug tsim nyog kub, thiab thaum kawg tau sulfur trioxide-triethylamine complex.
2. txoj kev sedimentation: thawj sulfur trioxide thiab triethylamine yog yaj nyob rau hauv cov kuab tshuaj uas tsim nyog, cov kuab tshuaj feem ntau yog carbon chloride los yog benzene. Lub complex yog tam sim no nyob rau hauv kev daws nyob rau hauv daim ntawv ntawm ib tug tov theem thiab yog sib cais thiab purified los ntawm kev daws.
Hais txog kev nyab xeeb cov ntaub ntawv:
1. Sulfur trioxide-triethylamine complex yog corrosive thiab irritating rau ntawm daim tawv nqaij thiab ob lub qhov muag. Hnav cov hnab looj tes tiv thaiv, tsom iav thiab tshuaj tiv thaiv khaub ncaws thaum ua haujlwm.
2. Lub compound tuaj yeem tsim cov pa roj carbon monoxide hauv qhov kub thiab txias. Kev ceev faj yuav tsum tau them rau qhov cua txias thiab tsis txhob sib cuag nrog cov khoom siv hluav taws xob.
3. Thaum lub sij hawm cia thiab siv, Sulfur trioxide-triethylamine complex yuav tsum raug cais tawm ntawm dej, oxygen thiab lwm yam oxidants kom tsis txhob muaj kev kub ntxhov.
Ua ntej ua ib qho kev sim ua haujlwm, thov nco ntsoov nkag siab txog qhov xwm txheej thiab cov ntaub ntawv kev nyab xeeb ntawm qhov sib xyaw kom meej, thiab ua raws li cov txheej txheem kev khiav hauj lwm thiab kev ntsuas kev nyab xeeb.
