Supercritical carbon dioxide yog tsis -} polar moleculic zoo li cov tshuaj nrog cov khoom hnyav loj.
Los ntawm kev ntxiv cov cosvent, lub solubility ntawm supercritical c ... tuaj yeem txhim kho, ua rau nws kom zoo dua yaj cov tshuaj Polar.
Piv txwv li, thaum rho cov nroj tsuagTseem Ceeb Roj, Flavonoids, Tag nrho saponins ntawm panaxisseng, thiab lwm yam, ethanol tuaj yeem txhim kho cov tshuaj tiv thaiv tau zoo.
Cov Cafolents nquag
Cawv
Xws li ethanol, isopropanol, etorropanol, etcharanol, ethanol yog ib qho uas nquag siv cov tshuaj tiv thaiv carbon dioxide rau cov tshuaj tsw qab. Piv txwv li, thaum rho tawm qee hom qoob loo polar los ntawm cov nroj tsuag, ntxiv qhov tsim nyog ntawm ethanol tuaj yeem nce cov kev rho tawm. IsoPropanol tseem qhia tau zoo hauv qee cov qauv.
Lwm cov kuab tshuaj organic
Xws li acetone, thiab lwm yam. Acetone muaj solubility zoo thiab volatility, txhim kho cov pa roj carbon dioxide zoo, txhim kho cov nyhuv tawm ntawm cov tshuaj yeeb zoo.
