Sonopropanol, eyaziwa nangokuthi2-propapol, uketshezi olungenamibala nangobala ngephunga elinamandla. Kuyinto evame ukusetshenziswa kwe-organic solvent. Ngenxa yezakhiwo zayo ezihlukile zamakhemikhali, zisetshenziswa kabanzi emikhakheni yezokwelapha, izimonyo, izimbobo kanye nama-solvents. Kodwa-ke, yini okufanele icatshangwe lapho uthenga i-isopropanol?

Qondisisa izindinganiso ezifunwayo kanye nekhwalithi:

Ngaphambi kokuthenga isopropanol, kubalulekile ukuba nokuqonda okucacile kwesidingo sakho bese unquma amazinga ekhwalithi we-isopropanol ethengiwe. Lokhu kungakusiza uqonde kangcono umkhiqizo owufunayo futhi uvikele ukuthenga imikhiqizo engalungile.

Khetha umthengisi ohlonishwayo:

Lapho ukhetha umthengisi, kubalulekile ukuqinisekisa ukuthi bangumthengisi osemthethweni. Ngokuvamile, imininingwane ethembekile yomthengisi ingatholakala ezinhlanganweni zezinhlobo zezimboni noma kumapulatifomu akwa-inthanethi aziwa kahle.

Intengo akuyona ukuphela kwento okufanele ucabangele:

Lapho uthengasowopropanol, intengo akufanele kube yiyona kuphela ukucatshangelwa. Ikhwalithi nensizakalo kubalulekile ngokulinganayo. Imikhiqizo enezintengo eziphansi akuyona ukukhetha okuhle kakhulu, ngakho-ke ukucatshangelwa ngokucophelela kuyadingeka.

Naka ukupakisha nokugcina:

Lapho uthenga i-sopropanol, kubalulekile ukubheka ukuthi ngabe indawo yokufaka nokugcina isitoreji kufanelekile. Ngisho nekhwalithi ephezulu ye-isopropanol ingaba nekhwalithi yayo isekelwe uma ingagcinwa kahle.

Ekuphetheni, kunezici eziningi okufanele zicatshangelwe lapho uthenga i-isopropanol. Amakhasimende kufanele abukeze ngokucophelela amazinga asezingeni, ukupakisha, nokugcina imvelo yomkhiqizo, bese ukhetha umthengisi ohlonishwayo ukuze aqinisekise ukuthenga okugculisayo.
