Acetone ndi chosungunulira chomwe chimagwiritsidwa ntchito kwambiri ndi mafakitale osiyanasiyana, kuphatikiza utoto, zomatira, ndi zamagetsi. Mowa wa Isopropyl ndiwonso wosungunulira wamba womwe umagwiritsidwa ntchito m'njira zingapo zopangira. Munkhaniyi, tiwona ngati acetone ingapangidwe kuchokera ku mowa wa isopropyl.
Njira yayikulu yosinthira mowa wa isopropyl kukhala acetone ndi kudzera munjira yotchedwa oxidation. Izi zimaphatikizapo kuchitapo kanthu ndi mowa ndi okosijeni, monga okosijeni kapena peroxide, kuti usinthe kukhala ketone yake yofananira. Pankhani ya mowa wa isopropyl, ketone yomwe imayambitsa ndi acetone.
Kuti muchite izi, mowa wa isopropyl umasakanizidwa ndi mpweya wa inert monga nayitrogeni kapena argon pamaso pa chothandizira. Chothandizira chomwe chimagwiritsidwa ntchito pochita izi nthawi zambiri chimakhala oxide yachitsulo, monga manganese dioxide kapena cobalt (II) oxide. Zomwezo zimaloledwa kupitiliza kutentha ndi kupsinjika.
Ubwino wina waukulu wogwiritsa ntchito mowa wa isopropyl ngati poyambira kupanga acetone ndikuti ndiwotsika mtengo poyerekeza ndi njira zina zopangira acetone. Kuonjezera apo, ndondomekoyi sikutanthauza kugwiritsa ntchito ma reagents othamanga kwambiri kapena mankhwala oopsa, zomwe zimapangitsa kuti zikhale zotetezeka komanso zotetezeka.
Komabe, palinso zovuta zina zokhudzana ndi njirayi. Chimodzi mwazovuta zazikulu ndikuti njirayi imafunikira kutentha kwambiri komanso kupanikizika, ndikupangitsa kuti ikhale yopatsa mphamvu. Kuonjezera apo, chothandizira chomwe chimagwiritsidwa ntchito pochitapo kanthu chingafunikire kusinthidwa nthawi ndi nthawi kapena kusinthidwa, zomwe zingapangitse mtengo wonse wa ndondomekoyi.
Pomaliza, ndizotheka kupanga acetone kuchokera ku mowa wa isopropyl kudzera munjira yotchedwa oxidation. Ngakhale kuti njirayi ili ndi ubwino wake, monga kugwiritsa ntchito zipangizo zoyambira zotsika mtengo komanso zosafunikira zotulutsa mphamvu kapena mankhwala owopsa, ilinso ndi zovuta zina. Zovuta zazikuluzikulu ndizofunika mphamvu zambiri komanso kufunikira kosinthira nthawi ndi nthawi kapena kukonzanso chothandizira. Chifukwa chake, poganizira kupanga acetone, ndikofunikira kuganizira mtengo wonse, kukhudzidwa kwa chilengedwe, komanso kuthekera kwaukadaulo kwa njira iliyonse musanapange chisankho panjira yoyenera kwambiri yopanga.
