Ukuze unciphise amanzi okungcola bese ukhuphula izinga lokuguqulwa kwemikhiqizo, izikhungo zokucwaninga zesayensi ezifuywayo ezisetshenziswayo zenqubo yasekhaya, kepha zithola imiphumela yemvelo ekhona, kepha kukhona ukukhethwa okuphezulu kwe-organ solvents, { Indlela ye-Solvent . Izindlela ezikhona zokukhishwa ze-solvent zifaka indlela ye-solvent crystallization, indlela yokususa i-distillation-uketshezi, indlela yokukhishwa eqinile, indlela yokukhipha uketshezi, ubuchwepheshe obungafani ne- .
Njengamanje, izixazululo ze-organic zingase zikhethe i-toluene, i-carbon dilelfide, aniline, i-benzene nokunye ku-.
Kusetshenziswa i-casbon disbent njenge-solvent, ukulawulwa kwezindleko nokulawulwa kokuphepha kuyizinkinga ezivelele . yize ikhwalithi ingahlangabezana nezidingo zomhlaba wonke, ukuphepha kudinga ukwenziwa ngcono ngenxa yokuvuselelwa kwekhabhoni .
Lapho i-aniline isetshenziswa njenge-solvent, i-aniline incane kancane emanzini, okuholela ekukhuphukeni kwenani le-aniline lekhambi, elingalungile ukukhiqizwa .}
Kusetshenziswa i-benzene ne-toluene njenge-solvents, i-solubility ye-resin incane, ubumsulwa bomkhiqizo m buyathinteka, futhi ukuguquguquka kwe-solvent kubhekwa futhi kuqhume, futhi kubangela ukulimala kwe-solvent emoyeni, kodwa futhi kubangela ukulimala ku imvelo yasemkhathini .
