Nke mbụ, kedu usoro eji eme acetone?Enwere ọtụtụ ụzọ isi mepụta acetone, n'ime nke a na-ahụkarị bụ oxidation catalytic nke propylene.Usoro a na-eji ikuku dị ka oxidant, ma na-eji ihe mkpali kwesịrị ekwesị iji gbanwee propylene n'ime acetone na hydrogen peroxide.Nhazi mmeghachi omume bụ nke a:

CH3CH=CH2 + 3/2O2→CH3COCH3 + H2O2

Ihe na-akpali akpali nke a na-eji na mmeghachi omume a na-abụkarị oxide nke titanium dioxide na-akwado na ụgbọelu inert dị ka.γ- Al2O3.Ụdị ihe nkedo a nwere ezigbo ọrụ na selectivity maka ntughari nke propylene na acetone.Na mgbakwunye, ụfọdụ ụzọ ndị ọzọ na-agụnye mmepụta nke acetone site dehydrogenation nke isopropanol, mmepụta nke acetone site hydrolysis nke acrolein, wdg.

Kedu ihe kemịkalụ na-eme acetone?Na usoro mmepụta nke acetone, a na-eji propylene eme ihe dị ka ihe eji eme ihe, a na-ejikwa ikuku dị ka oxidant.Ihe na-akpali akpali nke a na-eji na usoro a bụ titanium dioxide na-akwado yaγ- Al2O3.Na mgbakwunye, iji nweta acetone dị ọcha dị elu, mgbe mmeghachi omume ahụ gasịrị, a na-achọkarị nkewa na usoro nchacha dị ka distillation na ndozi iji wepụ ihe ndị ọzọ adịghị ọcha na ngwaahịa mmeghachi omume.
