Ishishini lamachiza licandelo elibalulekileyo uqoqosho lwehlabathi, elinoxanduva lokuvelisa iziyobisi ezindisa ubomi kunye nokunciphisa ukubandezeleka. Kweli shishini, iicomputer ezahlukeneyo kunye neekhemikhali zisetyenziswa ekuvelisweni kweziyobisi, kubandakanya ne-acetone. I-Acetone yikhemikhali eguquguqukayo efumana ukusetyenziswa okuninzi kumzi-mveliso wamachiza, kubandakanya nesinyibilikisi kunye nokuveliswa kweendlela ezahlukeneyo. Kweli nqaku, siza kuphonononga indima yei-acetonekumzi-mveliso wamayeza.

Kutheni i-acettone ingekho semthethweni

 

I-Acetone yi-alling engenabala, i-willile i-odor eqhelekileyo. Ingalunganga ngamanzi kwaye inyibilikiswe kwiinyibiliki ezininzi zezinto eziphilayo. Ngenxa yepropathi yayo yomzimba kunye nekhemikhali, i-acetone ifumana izicelo ezininzi kumashishini ahlukeneyo, kubandakanya amayeza.

 

Kumzi-mveliso wamayeza, i-acetone isetyenziswa njengesinyibilikisi. Inokunyibilikisa zombini izithintelo zepollar kunye ne-polar, zenza ukuba kubekho i-solvent efanelekileyo yoluhlu olubanzi lweefom zamayeza. I-Acetone esezantsi kakhulu kwaye iipropathi ezingenantlonelo zikwenza ukuba lukhethe ukhetho olubalaseleyo lokusetyenziswa kumalungiselelo amachiza.

 

Ngaphandle kokusetyenziswa kwayo njengesinyibilikisi, i-acetone ikwasebenziwe kwimveliso yeendlela ezahlukeneyo kumzi-mveliso wamachiza. Umzekelo, isetyenziswa kwi-synthesis yamaqhosha, ephakathi kwimveliso yamachiza ahlukeneyo. Ukusetyenziswa kwe-acetone kwezi zinto zinceda ukufumana amakhontshi afunekayo ngococeko oluphezulu kunye nesivuno.

 

Ngaphaya koko, i-acetone ikwasetyenziswa ekukhuthazeni izithako ezisebenzayo kwimithombo yendalo. Le nkqubo ibandakanya ukutyeshelwa kwesithako esisebenzayo kwi-acetone, emva koko icociwe kwaye igxile ukufumana iqula elicocekileyo. Le ndlela isetyenziswa ngokubanzi ekukhokeleni kwee-alkaloids, i-flavonoids, kunye nezinye izinto ze-biouses ezivela kwizityalo nakumayeza.

 

Kufanelekile ukukhankanya ukuba i-acetone ayisiyo kuphela i-selvent esetyenziswe kumzi-mveliso wamachiza. Ezinye izinyibilikisi eziqhelekileyo zibandakanya i-ethanol, i-methanol, kunye ne-Iyopropanol. Isinyibilifikethe ngasinye sinepropathi yayo eyahlukileyo kunye nezibonelelo, ezimisela ukufaneleka kwayo kwizicelo ezithile.

 

Ukuqukumbela, i-acetone idlala indima ebalulekileyo kumzi-mveliso wamachiza. Ukusetyenziswa kwayo njengesinyibilikisi kunye nokuveliswa kweenqobo ezahlukeneyo eziqinisekisa ukuvelisa iziyobisi ngokufanelekileyo kunye nexabiso lendleko. Iipropathi zayo zomzimba kunye nekhemikhali, ezidityaniswe netyhefu eziphantsi kakhulu zetyhefu, zenza ukuba kuthathe ukhetho oluhle kakhulu lokusetyenziswa kwifomu yamayeza. Njengoko ishishini lamayeza liyaqhubeka nokuphuhlisa kunye nokuphuhlisa amachiza amatsha, imfuno ye-acetone iya kuhlala iphezulu.
