I-acetoneNgaba lulwelo olungenabala, oluguqukayo olusetyenziswa ngokubanzi kwimveliso nangobomi bemihla ngemihla. Luhlobo lomzimba weKetone nge-molecular formiula c3h6o. I-acetone yinto enokutsha ngendlela ebilayo ye-56.11°C kunye nendawo yokunyibilika ye--94.99°C. Inephunga eliqaqambileyo elicaphukisayo kwaye liguquguquka kakhulu. Inyibiliza emanzini, ether, notywala, kodwa hayi emanzini. Sisixhobo esisebenzayo esibonakalayo kwishishini lekhemikhali, elinokusetyenziselwa ukuvelisa imichiza eyahlukeneyo, kwaye ikwasetyenziswa njengesinyibilikisi, isicoci, njl njl.

Zithini izithako zeAcetone? Nangona i-acetone yinxalenye yemichiza ecocekileyo, inkqubo yayo yemveliso ibandakanya uninzi lokuphendula. Makhe siqwalasele ukwakhiwa kwe-acetone ukusuka kwinkqubo yayo yemveliso.

Okokuqala, zithini iindlela zokwenza i-acetone? Zininzi iindlela zokuvelisa i-acetone, phakathi kweyona ixhaphakileyo yeyona ixhaphakileyo i-propylene ye-proplene. Le nkqubo isebenzisa umoya njenge-oxidant, kwaye isebenzise eyona nto ifanelekileyo yokuguqula i-propleyne ibe yi-acetone kunye ne-hydrogen peroxide. Indlela yokuphendula imi ngolu hlobo lulandelayo:

Ch3ct = ch2 + 3 / 2o2→Ch3coch3 + h2o2

I-Catalyst isetyenziswe kule mpendulo ihlala i-oxidey ye-titanium dioxide ixhaswe kwi-Inert ithwaxwa kwiγ-Al2o3. Olu hlobo lokuthambisa lunemisebenzi elungileyo kunye nokukhetha ukuguqulwa kwe-proplene ukuya kwi-acetone. Ukongeza, ezinye iindlela zibandakanya ukuveliswa kwe-acetone ngokuphumelela kwe-isopropanol, ukuveliswa kwe-acetone yi-hydrolysis ye-hrolein, njl.

Ke zeziphi iikhemikhali ezenza i-acetone? Kwinkqubo yemveliso ye-acetone, i-propylene isetyenziswa njengezixhobo eziluhlaza, kwaye umoya usetyenziswa njengokhosa. I-Catalyst esetyenzisiweyo kule nkqubo ihlala i-Titanium Dioxide ixhasweγ-Al2o3. Ukongeza, ukuze ufumane i-Acetone ePhezulu, emva kokuphendula, ukwahlula kunye namanyathelo okuCoca efana nokuphatha kunye nokulungiswa kuyafuneka ukususa ezinye izinto ezenzekayo kwimveliso yokuphendula.

Ukongeza, ukuze ufumane i-Acetone ePhezulu, ukwahlukana nokuCoca izicwangciso ezinjengokuphazamiseka kunye nokulungiswa kuyafuneka ukususa ezinye izinto zokungcola. Ukongeza, ukwenzela ukukhusela indalo kunye nempilo yabantu, amanyathelo afanelekileyo onyango kufuneka athathwe kwinkqubo yemveliso ukunciphisa ungcoliseko kunye nokukhutshwa.

Ngamafutshane, inkqubo yemveliso ye-acetone ibandakanya izinto ezininzi zokuphendula kunye namanyathelo, kodwa ezona zinto ziphambili ze-prow kunye ne-oxidant zisebenza kunye nomoya ngokwahlukeneyo. Ukongeza, i-titanium dioxide ixhasweγ-U -l2o3 uhlala usetyenziswa njengokukhulisa ukukhuthaza inkqubo yokuphendula. Ekugqibeleni, emva kokwahlukana nokucoca amanyathelo njengokuphazamiseka nokulungiswa, i-acetone ephezulu inokufumaneka ukuze isetyenziswe kwizicelo ezahlukeneyo.
