txhais ntawm tshuaj active extraction . ib txoj kev sib cais uas siv acid-puag chemistry hloov ib qho compound hloov nws cov solubility tso cai rau kev sib cais ntawm ib qho sib tov.

Yog li ntawd, dab tsi yog qhov txawv ntawm ib qho extraction thiab ib tug tshuaj active extraction?

Nws yog ib txoj hauv kev ntawm cais ib qho kev xav tau los ntawm kev sib tov. Kev sib cais nws tus kheej feem ntau yog nyob ntawm polarity qhov sib txawv ntawm lub molecule koj xav nyob rau hauv cais thiab lwm yam khoom ntawm qhov sib tov. Hom no ntawm kev sib cais hu ua a tshuaj active extraction.

Ib yam li ntawd, cov txheej txheem ntawm kev rho tawm yog dab tsi? Kev rho tawm yog a txheej txheem nyob rau hauv uas ib los yog ntau lub Cheebtsam yog cais los ntawm ib tug ua kua los yog cov khoom sib tov, pub (Phase 1), los ntawm cov kua immiscible hnyav (Phase 2). Tom qab ntawd txhawm rau txhawm rau rov tsim cov kuab tshuaj, lwm qhov kev sib cais (piv txwv li distillation) yog qhov kawg.

Ua raws li qhov no hauv kev txiav txim siab, koj yuav ua li cas extractions hauv organic chemistry?

Ib qho kev daws teeb meem uas muaj cov khoom tawg tau muab tso rau hauv qhov funnel thiab ib qho hnyav hnyav ntxiv, uas ua rau ob txheej uas tau shaken ua ke. Nws yog feem ntau rau ib txheej yuav aqueous thiab lwm yam organic kuab tshuaj. Cheebtsam yog " rho tawm "Thaum lawv txav ntawm ib txheej mus rau lwm qhov.

Dab tsi yog hom kev rho tawm?

Peb feem ntau hom ntawm extractions yog: kua / kua, kua / khoom, thiab acid / puag (tseem hu ua ib tug active tshuaj. rho tawm ). Cov piv txwv kas fes thiab tshuaj yej yog ob qho tib si ntawm cov kua / khoom hom nyob rau hauv uas ib tug compound (caffeine) yog cais los ntawm cov khoom sib tov los ntawm kev siv cov kua rho tawm kuab tshuaj (dej).
