Thaum lub sijhawm rho tawm, cov txheej txheem organic feem ntau yog nyob rau sab saum toj thiab cov txheej txheem dej yog nyob hauv qab hauv qhov sib cais. Muab ib qho piv txwv tshwj xeeb ntawm cov kuab tshuaj organic uas, thaum siv thaum lub sijhawm rho tawm, yuav yog txheej hauv qab, yuam cov aqueous mus rau saum.
Dab tsi yog txheej txheej organic hauv kev rho tawm?
Nyob rau hauv cov txheej txheem no, cov khoom organic yog cais los ntawm inorganic tshuaj. Cov organic khoom yuav soluble hauv cov organic hnyav(organic txheej) thaum cov tshuaj inorganic yuav soluble hauv dej (aqueous txheej).
Koj paub li cas txheej twg yog cov organic hauv kev rho tawm?
Kev piav qhia: Saib lub rooj ntawm tus swb dhau los. Nyob rau sab laug sib cais funnel, aqueous txheej nyob rau hauv qab, txhais tau tias cov organic txheej yuav tsum tsawg dua cov dej. Nyob rau hauv txoj cai sib cais funnel, txheej aqueous yog nyob rau sab saum toj, txhais tau tias cov organic txheej yuav tsum ntom dua dej.
Dab tsi mus rau hauv cov txheej txheem organic?
Muaj cov organic txheej, uas yog insoluble hauv dej thiab pib muaj tag nrho koj cov tebchaw uas koj yuav nws thiaj li sib cais. Cov txheej txheem organic kuj muaj solvent (CH2Cl2 lossis ether) uas yog insoluble hauv dej. Yog li cov organic txheej=Compounds peb tab tom sim cais + insoluble hnyav.
Puas yog txheej organic ib txwm nyob saum?
Ob txheej yogfeem ntau hu ua aqueous theem thiab theem organic. … Rau cov kuab tshuaj sib zog dua dej (piv txwv li, qhov ceev < 1),cov txheej txheem organic yuav nyob rau sab saum toj ntawm qhov sib cais, qhov hnyav dua dej (qhov ntom > 1) yuav tog rau hauv hauv qab (Daim duab 1).
