I-acetoneluhlobo lwesimo se-solganic, esisetyenziswa ngokubanzi kumashishini ahlukeneyo. Inkqubo yayo yemveliso inzima kakhulu kwaye ifuna iintlobo ezahlukeneyo zokuphendula kunye nokucamngca. Kweli nqaku, siya kuhlalutya inkqubo yokuvelisa ye-acetone evela kwizixhobo eziluhlaza kwiimveliso.

 

Okokuqala, izinto ezingafunekiyo zeAcetone yi-Benzene, efunyanwa kwioyile okanye ye-Coal Tar. I-Bengezene iphinda iphinde iphendulwe kunye ne-Steam kwiqondo lobushushu eliphezulu kunye ne-reactor-uxinzelelo oluphezulu ukuvelisa umxube we-cyclohexane kunye ne-Benzene. Le ndlela yokuphendula kufuneka yenziwe kwiqondo lokushisa eliphezulu lama-300 degrees Celsius kunye noxinzelelo oluphezulu lwe-3000 psi.

 

Emva kokuphendula, umxube ufumaneka phantsi kwaye wahlukaniswe ngamacandelo amabini: umaleko weoyile ngaphezulu kunye nomgca wamanzi ezantsi. Umaleko weoyile uqukethe i-cyclohexane, Benzene kunye nezinye izinto, ekufuneka zenziwe ngokwamanqanaba aphantsi okufumana i-cyclohexane ecocekileyo.

 

Kwelinye icala, umaleko wamanzi uqukethe i-acetic acid kunye ne-cyclohexungXanol, ekwabalulekile kwezinto ezibalulekileyo zokuveliswa kwe-acetone. Kweli nyathelo, i-acetic acid kunye ne-cycloheXanol yahlulwe omnye komnye ngediliya.

 

Emva koko, i-acetic acid kunye ne-cycloheXanol ixutywe ne-sulfuric acid egxile kwi-aced ukuba ivelise ubunzima obuqulathe i-acetone. Oku kuphendula kufuneka kwenziwe kwiqondo lokushisa eliphezulu le-120 degrees Celsius kunye noxinzelelo oluphezulu lwe-200 psi.

 

Okokugqibela, ubunzima bokuphendula bahlukaniswe nomxube we-distration, kwaye i-acetone ecocekileyo ifunyenwe ephezulu kwikholamu. Eli nyathelo lisusa ukungcola okushiyekileyo njengamanzi kunye ne-acetic acid, iqinisekisa ukuba i-acetone idibana nemigangatho yemveliso.

 

Ukuqukumbela, inkqubo yemveliso ye-acetone inzima kwaye ifuna iqondo lobushushu elingqongqo, uxinzelelo kunye namanyathelo okucoca ukufumana iimveliso ezisemgangathweni. Ukongeza, izinto ezibukhali ze-bebene zifumaneka kwioyile okanye kwi-Coal Tar, enefuthe elithile kwindalo esingqongileyo. Ke ngoko, kufuneka sikhethe iindlela ezizinzileyo sokuvelisa i-wacetone kwaye sinciphise ifuthe kwindalo esingqongileyo kangangoko kunokwenzeka.
