I-Iyopropanol, ekwabizwa ngokuba yi-Iyopropyl Utywala okanye i-2-propanol, lulwelo olungenamibala, olunokutsha olune-odor eqhelekileyo. Yinto esetyenzisiweyo yemichiza esetyenzisiweyo esetyenziswayo efumana izicelo kuluhlu lwamashishini, kubandakanya amayeza, cosmetics, kunye neemveliso zokutya zokutya. Kweli nqaku, siza kuxhomekeka kwigama eliqhelekileyo le-isopropanol kunye nokusebenzisa kwayo kunye neepropathi.

Indlela ye-Iyopropanol Synthesis

 

Ibinzana elithi "Iyoparopanol" libhekisa kwiklasi yemichiza yemichiza enamaqela asebenzayo asebenzayo kunye nemo yemolekyuli njenge-ethanol. Umahluko ulele kwinto yokuba i-Iyopropanol ineqela le-methyl eyongezelelweyo eliqhotyoshelwe kwi-carbon atom ekufuphi neqela le-hydroxyl. Eli qela le-ITHYL olongezelelekileyo linika i-Iyopropanol eyahlukileyo yomzimba kunye neekhemikhali xa kuthelekiswa ne-ethanol.

 

I-Iyopropanol iveliswa mveliso ngeyona ndlela iphambili ngeendlela ezimbini eziphambili: Inkqubo ye-ACEtone-Butanol kunye nenkqubo ye-propleylene. Kwinkqubo ye-Acetone-Butanol, i-Acetone kwaye i-Acetone kwaye i-Butanol iphendulwa phambi kwe-acid catalyst ivelise i-Iyopropanol. Inkqubo ye-proplenene oxide ibandakanya impendulo ye-proplenene ngeoksijini ebusweni be-proplyst ukuba ivelise i-propylene glycol, eguqulwe ibe yiyoparopanol.

 

Enye yezona zinto zixhaphakileyo ze-isopropanol zikumveliso ye-cosmetics kunye neemveliso zononophelo lomntu. Ihlala isetyenziswa njengesinyibilikisi kwezi mveliso ngenxa yomoya wokuzola kunye neepropathi ezingenakucaphukiswa. Ukongeza, ikwasetyenziswa kwimveliso yezicoci zamakhaya, apho iipropathi zawo zentshutshiso zisetyenziswa kakuhle. Kumzi-mveliso wamayeza, i-Ispropanol isetyenziswa njengesinyibilikisi kumalungiselelo amachiza kwaye njengento engafunekiyo ye-synthesis yezinto ezithile zamayeza.

 

Ngapha koko, i-Iyopropanol ikwasetyenziswa kumzi mveliso wokulungisa ukutya njengearhente yencasa kunye nokugcinwa. Ihlala ifumaneka ngokutya okuthe kratya njenge-jams, iijellies, kunye neziselo ezithambileyo ngenxa yokwandisa incasa kunye neshellong shel. Ityhefu esezantsi ye-Iyopropanol ivumela ukuba isetyenziswe ngokukhuselekileyo kwezi zicelo.

 

Ukuqukumbela, i-Isupropanol yinto esetyenziswa ngokubanzi yekhemizi enemizi-mveliso emininzi. Ulwakhiwo lwayo lwemolekyuli olukhethekileyo kunye neepropathi zomzimba zenza ukuba lungenise ngaphakathi kumashishini ahlukeneyo, kubandakanya i-cosmetics, amayeza, kunye nokulungiswa kokutya. Ulwazi ngegama lawo eliqhelekileyo kunye nokusetyenziswa kwayo kubonelela ngokuqonda okungcono kule chiza lemichiza yokutshintsha.
