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).

Dab tsi yog equidistant los ntawm peb sab ntawm daim duab peb sab?
Lub ntsiab lus uas sib npaug rau txhua sab ntawm daim duab peb sab yog hu ua incenter: Ib qho nruab nrab yog ib qho kab uas muaj ib qho ntawm nws qhov kawg ntawm lub vertex ntawm daim duab peb sab thiab lwm qhov kawg ntawm qhov nruab nrab ntawm sab opposite lub vertex. Peb qhov nruab nrab ntawm ib daim duab peb sab sib ntsib hauv centroid
Peb txhais li cas los ntawm ecology?
Txhua yam kab mob, tsis hais lawv qhov loj me, lawv hom, lossis lawv nyob qhov twg, yuav tsum muaj kev cuam tshuam nrog lwm cov kab mob hauv lawv cov 'neighborhood' thiab nrog lawv ib puag ncig kom muaj sia nyob. Ecology yog kev tshawb fawb txog kev sib cuam tshuam ntawm cov kab mob thiab lawv ib puag ncig
Vim li cas nws thiaj li hais tias lub Orthocenter ntawm daim duab peb sab obtuse yuav tsum nyob rau sab nraud ntawm daim duab peb sab?
Nws hloov tawm tias tag nrho peb qhov siab ib txwm sib tshuam ntawm tib lub ntsiab lus - lub npe hu ua orthocenter ntawm daim duab peb sab. Lub orthocenter tsis yog ib txwm nyob hauv daim duab peb sab. Yog tias daim duab peb sab yog obtuse, nws yuav nyob sab nraud. Txhawm rau ua kom qhov no tshwm sim cov kab qhov siab yuav tsum tau txuas ntxiv kom lawv hla
Vim li cas nws yog ib lub tswv yim zoo los cawm tag nrho cov txheej txheem ntawm koj cov extraction kom txog thaum kawg ntawm kev sim?
Kev ua yuam kev thaum lub sijhawm rho tawm (piv txwv li nqa nrog cov txheej txheem tsis raug), tuaj yeem daws tau yog tias cov kev daws tsis tau muab tso rau hauv lub thawv pov tseg! Cov khaubncaws sab nraud povtseg yuav tsum tau txais kev cawmdim kom txog thaum tom qab evaporation vim hais tias cov khoom xav tau yuav tsis soluble heev hauv cov kuab tshuaj siv
Txhais tau li cas los txhais ib daim duab peb sab?
Kev txhais lus. Kev txhais lus yog ib qho kev hloov pauv uas tshwm sim thaum ib daim duab tau txav los ntawm ib qho chaw mus rau lwm qhov chaw yam tsis tau hloov nws qhov loj, duab lossis kev taw qhia. Txhawm rau txhais cov ntsiab lus P (x, y), ib chav nyob sab xis thiab b units, siv P'(x + a, y + b)
