I-Isopropyl alcohol, eyaziwa nangokuthiisopropanolnoma ukuxubha utshwala, iyisibulala-magciwane esisetshenziswa kakhulu kanye ne-ejenti yokuhlanza. Futhi iyi-reagent evamile yaselabhorethri kanye ne-solvent. Ezimpilweni zansuku zonke, utshwala be-isopropyl buvame ukusetshenziselwa ukuhlanza nokubulala amagciwane ama-Bandaids, okwenza ukusetshenziswa kotshwala be-isopropyl kuvame kakhulu. Kodwa-ke, njengezinye izinto zamakhemikhali, i-isopropyl alcohol nayo izoba nezinguquko kuzakhiwo nokusebenza ngemva kokugcinwa isikhathi eside, futhi ingase ibe yingozi empilweni yomuntu uma isetshenziswa ngemva kokuphelelwa yisikhathi. Ngakho-ke, kuyadingeka ukwazi ukuthi i-isopropyl alcohol izophelelwa yisikhathi.

Ukuze siphendule lo mbuzo, kudingeka sicabangele izici ezimbili: ukuguqulwa kwezakhiwo ze-isopropyl alcohol ngokwayo kanye nomthelela wezinto zangaphandle ekuzinzeni kwayo.

Okokuqala, i-isopropyl alcohol ngokwayo inokungazinzi okuthile ngaphansi kwezimo ezithile, futhi izobhekana nezinguquko zezakhiwo nokusebenza ngemva kokugcinwa isikhathi eside. Isibonelo, i-isopropyl alcohol izobola futhi ilahlekelwe izici zayo zangempela lapho ivezwe ekukhanyeni noma ekushiseni ngaphansi kwezimo ezithile. Ngaphezu kwalokho, ukugcinwa isikhathi eside kungase futhi kuholele ekukhiqizeni izinto eziyingozi ku-isopropyl alcohol, njenge-formaldehyde, i-methanol nezinye izinto, ezingase zibe nomthelela omubi empilweni yomuntu.

Okwesibili, izici zangaphandle ezifana nezinga lokushisa, umswakama nokukhanya kuzophinde kuthinte ukuzinza kwe-isopropyl alcohol. Isibonelo, izinga lokushisa eliphezulu nomswakama kungase kukhuthaze ukubola kwe-isopropyl alcohol, kuyilapho ukukhanya okunamandla kungase kusheshise ukusabela kwayo kwe-oxidation. Lezi zici zingase futhi zinciphise isikhathi sokugcinwa kwe-isopropyl alcohol futhi zithinte ukusebenza kwayo.

Ngokocwaningo olufanele, impilo yeshalofu ye-isopropyl alcohol incike ezintweni eziningi ezifana nokugxilisa ingqondo, izimo zokugcina nokuthi ivaliwe yini. Ngokuvamile, impilo yeshalofu ye-isopropyl alcohol ebhodleleni cishe unyaka owodwa. Kodwa-ke, uma ukuhlushwa kwe-isopropyl alcohol kuphezulu noma ibhodlela lingavalwanga kahle, impilo yalo yeshalofu ingase ibe mfushane. Ngaphezu kwalokho, uma ibhodlela le-isopropyl alcohol livulwa isikhathi eside noma ligcinwe ngaphansi kwezimo ezimbi ezifana nokushisa okuphezulu nomswakama, lingase futhi lifinyeze impilo yalo yeshalofu.

Kafushane, i-isopropyl alcohol izophelelwa yisikhathi ngemva kokugcinwa isikhathi eside noma ngaphansi kwezimo ezimbi. Ngakho-ke, kunconywa ukuthi uyisebenzise kungakapheli unyaka owodwa ngemva kokuyithenga futhi uyigcine endaweni epholile nemnyama ukuze uqinisekise ukuzinza nokusebenza kwayo. Ngaphezu kwalokho, uma uthola ukuthi ukusebenza kwe-isopropyl alcohol kushintsha noma umbala wayo ushintsha ngemva kokugcinwa isikhathi eside, kunconywa ukuthi ungayisebenzisi ukuze ugweme ukulimaza impilo yakho.
