Propylene Carbonate Synthesis txheej txheem thiab nruj impurity tswj rau roj teeb -Qib khoom

High-Propylene Carbonate zoo yog tsim los ntawm kev sib xyaw ua ke thiab ntau-theem purification txheej txheem. Cov cuab yeej siv technology thiab impurity tswj system ncaj qha txiav txim siab cov khoom purity thiab daim ntawv thov kev ua tau zoo, tshwj xeeb tshaj yog rau cov roj teeb - cov khoom qib nrog ultra- cov kev xav tau zoo.

 

Cov txheej txheem tseem ceeb ntawm propylene Carbonate txais yuav propylene oxide carbonylation synthesis txoj kev. propylene oxide thiab carbon dioxide yog siv los ua cov khoom siv raw, thiab siab -cov khoom siv hluav taws xob tau ntxiv rau kaw- cov tshuaj tiv thaiv kab mob nyob rau hauv qhov kub thiab txias. Cov txheej txheem no muaj cov tshuaj tiv thaiv kev ua haujlwm siab, tsawg los ntawm - cov khoom, thiab cov khoom lag luam ruaj khov yooj yim purity, uas yog cov txheej txheem kev tsim ntsuab ntsuab hauv kev lag luam.

 

Tom qab cov khoom lag luam raug tsim tawm, nws yuav tsum tau ua ntau yam -stage distillation, dehydration, thiab impurity tshem tawm kev kho mob. Cov khoom lag luam ib txwm muaj- qib cov khoom lag luam tsuas yog xav tau yooj yim distillation, thaum lub roj teeb - qibPropylene Carbonateyuav tsum tau ultra-kev kho kom raug, molecular sieve dehydration, thiab hlau ion pom. Ntau cov txheej txheem purification zoo tshem tawm cov kab ya raws, acidic tshuaj, thiab hnyav hlau impurities.

 

Cov ntsiab lus tswj tau zoo muaj xws li cov ntsiab lus noo noo, acidity tus nqi, chromaticity, thiab hlau ion residue. Roj teeb- cov khoom qib yuav tsum muaj cov dej noo hauv qab 10ppm thiab xoom hnyav hlau ions, uas tuaj yeem ua kom muaj kev nyab xeeb thiab kev ruaj ntseg ntawm lithium roj teeb electrolyte. Txhua batch ntawm cov khoom yuav raug kuaj nruj me ntsis thiab nrog rau cov ntaub ntawv COA ua ntej xa khoom.

 

Kev paub ntau lawm technology thiab nruj impurity tswj system ua rau Suav Propylene Carbonate cov khoom los tuav ib tug tseem ceeb txoj hauj lwm nyob rau hauv lub ntiaj teb no siab -kawg lag luam. Nws tau dhau los ua cov khoom lag luam nyiam rau txawv teb chaws tshiab zog thiab hluav taws xob tsim lag luam.
