Kev rho tawm cov khoom los ntawm cov khoom khib nyiab lossis kua raws li kev siv SCFs hauv kev lag luam. Qhov zoo ntawm kev siv sub thiab supercritical kua nyob rau hauv tunability ntawm hnyav zog. … Supercritical fluids yog solvents rau yav tom ntej.
Vim li cas cov kua dej supercritical yog cov kuab tshuaj zoo?
Lub peev xwm ntawm supercritical CO2 ua kom yaj mus rau hauv cov polar organic hnyav thiab nthuav qhov ntim ntawm cov kuab tshuaj 10 npaug txo qhov solubility ntawm yaj tebchaw thiab pib nag lossis daus ntawm yav tas los yaj hais nyob rau hauv lub expanded hnyav.
Puas yog cov kua dej supercritical yog cov kuab tshuaj?
Supercritical fluids muaj solvent power zoo ib yam li lub teeb hydrocarbon rau feem ntau cov kuab tshuaj . Txawm li cas los xij, cov tshuaj fluorinated feem ntau yog soluble ntau dua hauv scCO2 dua li hauv hydrocarbons; Qhov no nce solubility yog ib qho tseem ceeb rau polymerization. Solublity nce nrog nce ceev (piv txwv li nrog nce siab).
Cov kua dej supercritical hloov pauv yog dab tsi?
Lawv yog siv los hloov cov kuab tshuaj organic hauv ntau qhov kev lag luam thiab cov txheej txheem kuaj. Cov pa roj carbon dioxide thiab dej yog cov kua dej ntau tshaj plaws; lawv feem ntau siv rau decaffeination thiab tsim hluav taws xob, feem.
Vim li cas cov kua dej supercritical tseem ceeb?
Ib qho ntawm cov khoom tseem ceeb ntawmsupercritical fluids yog lawv lub peev xwm los ua cov kuab tshuaj. Solubility nyob rau hauv cov kua supercritical zoo li nce nrog qhov ceev ntawm cov kua (ntawm qhov kub thiab txias). Txij li qhov ceev nce nrog siab, solubility nyhav nce nrog siab.
