Ii-fat analyzericola into eqinileyo phambi kokutsalwa ukwandisa indawo yoqhagamshelwano oluqinileyo. Emva koko, faka into eqinileyo kwisikhwama sephepha lokucoca kwaye uyibeke kwi-extractor. Isiphelo esisezantsi se-extractor sixhunyiwe kwi-flask ephantsi ejikelezayo equkethe i-solvent leaching (i-ether anhydrous okanye i-petroleum ether, njl.), kwaye i-condenser ye-reflux ixhunyiwe kuyo.
Iflaski engqukuva esezantsi iyafudunyezwa ukwenza isinyibilikisi sibile. Umphunga ukhuphuka ngombhobho wokudibanisa kwaye ungene kwi-condenser. Emva kokuba icutshiwe, ithontsizela kwi-extractor. Isinyibilikisi sidibana nesiqina ukuze sitsalwe. Xa inqanaba le-solvent kwi-extractor lifikelela kwinqanaba eliphezulu le-siphon , I-solvent equkethe i-extract iphinda ifakwe kwi-flask, ngaloo ndlela ikhupha inxalenye yento. Emva koko i-solvent ye-leaching kwi-flask ejikelezayo ephantsi iyaqhubeka i-evaporate, i-condense, i-leaching, kunye ne-reflux, kwaye iphinda le nkqubo, ukuze into eqinileyo ikhutshwe ngokuqhubekayo yi-solvent leaching ecocekileyo, kwaye into ekhutshiweyo iphuculwe kwi-flask.
Ukukhutshwa kwe-Liquid-solid kusebenzisa i-solvents ukufezekisa injongo yokukhupha kunye nokwahlula ngokusebenzisa i-solvents ene-solubility enkulu kumacandelo afunekayo kumxube oqinileyo kunye ne-solubility encinci yokungcola.
USiphon: Ulwakhiwo lwe-tubular olujikiweyo olumilise u-U.
I-Siphon isiphumo: I-Siphon yi-hydrodynamic phenomenon esebenzisa umahluko kwinqanaba lolwelo ukwenza amandla, anokufunxa ulwelo ngaphandle koncedo lwempompo. Emva kokuba i-liquid kwindawo ephezulu igcwalise i-siphon, i-liquid kwi-container iya kuqhubeka iphuma kwindawo ephantsi nge-siphon. Ngaphantsi kwesi sakhiwo, umahluko woxinzelelo lwamanzi phakathi kweziphelo ezimbini zombhobho unokutyhala ulwelo kwindawo ephezulu kwaye ukhuphe kwelinye icala.
Amafutha akrwada: Emva kokuba isampulu itsalwe nge-ether eneanhydrous okanye i-petroleum ether kunye nezinye izinyibilikisi, into efunyenwe ngokukhupha umphunga kwi-solvent ibizwa ngokuba ngamafutha okanye akrwada kuhlalutyo lokutya. Ngenxa yokuba ngaphezu kwamafutha, iqulethe i-pigments kunye neoli eguqukayo, i-wax, i-resins kunye nezinye izinto.
Thumela umyalezo wakho kuthi:
