Njengomthetho ojwayelekile, i-acetone iwumkhiqizo ovame kakhulu futhi obalulekile otholakala ku-distillation yamalahle. Esikhathini esedlule, yayisetshenziswa kakhulu njengempahla eluhlaza yokukhiqiza i-cellulose acetate, i-polyester namanye ama-polymers. Eminyakeni yamuva nje, ngokuthuthuka kobuchwepheshe kanye nokushintshwa kwesakhiwo sempahla eluhlaza, ukusetshenziswa kwe-acetone nakho kuye kwandiswa ngokuqhubekayo. Ngaphezu kokusetshenziswa njengento eluhlaza yokukhiqiza ama-polymers, ingasetshenziswa futhi njenge-solvent esebenza kahle kakhulu kanye ne-ejenti yokuhlanza.
Okokuqala, ngokombono wokukhiqiza, impahla eluhlaza yokukhiqiza i-acetone ngamalahle, uwoyela negesi yemvelo. E-China, amalahle ayimpahla eluhlaza eyinhloko yokukhiqiza i-acetone. Inqubo yokukhiqiza i-acetone iwukuba i-distillate amalahle ekushiseni okuphezulu nezimo zokucindezela okukhulu, ukukhipha nokucwenga umkhiqizo ngemva kokufiphala kokuqala nokuhlukaniswa kwengxube.
Okwesibili, ngokombono wesicelo, i-acetone isetshenziswa kabanzi emkhakheni wezokwelapha, udayi, izindwangu, ukuphrinta nezinye izimboni. Emkhakheni wezokwelapha, i-acetone isetshenziswa ngokuyinhloko njenge-solvent yokukhipha izithako ezisebenzayo ezitshalweni zemvelo nasezilwaneni. Emasimini e-dyestuffs kanye nezindwangu, i-acetone isetshenziswa njenge-ejenti yokuhlanza ukususa amafutha kanye ne-wax ezindwangu. Emkhakheni wokunyathelisa, i-acetone isetshenziselwa ukuncibilikisa oyinki bokuphrinta futhi isuse amafutha kanye ne-wax kumapuleti okuphrinta.
Okokugcina, ngokombono wesidingo semakethe, ngokuthuthuka komnotho waseChina kanye nokushintsha kwesakhiwo sempahla eluhlaza, isidingo se-acetone sikhula njalo. Njengamanje, isidingo saseChina se-acetone sifika kuqala emhlabeni, sibalwa ngaphezu kwama-50% engqikithi yomhlaba wonke. Izizathu eziyinhloko ukuthi i-China inezinsiza zamalahle ezicebile kanye nesidingo esikhulu sama-polymers ezindaweni zokuhamba nezokwakha.
Ukufingqa, i-acetone iyinto evamile kodwa ebalulekile yamakhemikhali. E-China, ngenxa yemithombo yayo ecebile yamalahle kanye nesidingo esikhulu sama-polymer emikhakheni ehlukahlukene, i-acetone isiphenduke enye yezinto ezibalulekile zamakhemikhali ezinamathemba amahle emakethe.
