Amafutha ayisakhamzimba esibalulekile kubantu. Uma ugwema ngobumpumputhe izakhi zamafutha, kuzodala uchungechunge lwezinkinga ezifana nokungondleki. Ngaphezu kwalokho, izinga lokuqukethwe kwamafutha libuye libe yinkomba ebalulekile yekhwalithi yokudla kanye nenani lokudla okunempilo. Ngakho-ke, ukuzimisela kwamafutha sekuyisikhathi eside kuyinto evamile yokuhlaziya ukudla nokudla. Iamafutha analyzeringanquma ngokunembile okuqukethwe kwamafutha ekudleni. Amafutha angcolile ekudleni athinta ngokuqondile ukusetshenziswa kwawo. Isibonelo, ubhontshisi wesoya onamafutha amaningi aluhlaza asetshenziswa kakhulu ekukhishweni kukawoyela, kanti ukudla okusele kukabhontshisi wesoya kusetshenziswa njengokuphakelayo, njll.; ubhontshisi wesoya okhipha uwoyela ophansi usetshenziswa kakhulu ekucubunguleni ukudla.
.
Indlela ejwayelekile isetshenziswa ukunquma ukuthi kungakanani amafutha aluhlaza ekudleni. Okokuqala, kusetshenziswa ibhodlela elihlala njalo elithola isisindo, bese isampula ezohlolwa ikhishwa nge-ether anhydrous noma i-petroleum ether. Ngemuva kokukhipha, i-ether engamanzi noma i-petroleum ether iyatholwa futhi ihwamuke ibe yomile, bese kudluliswa ibhodlela lokwamukela isisindo njalo. Amafutha aluhlaza okudla abalwa ngokukala ibhodlela elamukelayo ngaphambi nangemuva kokukhipha. Indlela ethuthukisiwe yesampula yesisindo esiqhubekayo + ishubhu lephepha lokuhlunga, bese ucwilisa isampula nge-ether anhydrous noma i-petroleum ether, ngemva kokuqedwa kokukhipha, bese kuba isampula + leshubhu lephepha lokuhlunga ngemva kokukhipha isisindo esiqhubekayo, ngokukala ukuguqulwa kwesisindo sesampula + ishubhu lephepha lokuhlunga ngaphambi nangemva kokukhipha, bala ukudla okungahluziwe. okuqukethwe kwamafutha. Indlela ethuthukisiwe ayikwazi ukunqoba kuphela amaphutha ahlelekile abangelwa ukusetshenziswa kwesikhathi eside kwebhodlela elitholayo, kodwa futhi ithuthukise ukunemba kokuhlaziywa kanye nemiphumela yokunquma, futhi ingathuthukisa ukunemba kokuhlaziywa nokunciphisa izindleko, futhi kufanelekile ukuzimisela kwamafutha angcolile ekudleni.
.
Kuyaqondakala ukuthi le ndlela yokulinganisa yendabuko nayo ingenzeka, kodwa futhi izoletha umsebenzi omningi. Uma ingatholwa ngemitha yamafutha, ilula futhi inembile, futhi kungathiwa iyindlela engcono kakhulu.
Thumela umlayezo wakho kithi:
