Ukuhlaziywa kwemakethe kwakamuva kugqamisa ukuthi i-cyclohexanone, ikhemikhali ebalulekile ephathelene namakhemikhali e-organic, iyaqhubeka nokugcina isidingo esizinzile somhlaba wonke, njengoba ukusetshenziswa kwayo kukhula emikhakheni eminingi yezimboni—okusekela ukukhula emikhakheni esukela kuma-polymer kuya kumakhemikhali akhethekile.
Njengoketshezi olungenambala kuya kophuzi olukhanyayo olunephunga elifana ne-mint nelifana ne-acetone, i-cyclohexanone idunyiswa ngendima yayo emibili njengesithako esisebenza kahle kanye nesakhiwo esiyinhloko sokwenziwa kwamakhemikhali. Ukusetshenziswa kwayo okuvelele kakhulu kusekukhiqizweni kwe-adipic acid kanye ne-caprolactam, ama-monomer amabili abalulekile ekukhiqizeni i-nylon 6 kanye ne-nylon 66. Lawa ma-nylon asetshenziswa kabanzi ezindwangu, epulasitikini lobunjiniyela bezimoto, nasezintweni zokupakisha, okudala isidingo esiqhubekayo se-cyclohexanone phakathi kokukhula okuqhubekayo embonini yezindwangu zomhlaba kanye nezimoto.
Ngaphandle kokwenziwa kwe-polymer, amandla amahle kakhulu okuncibilikisa e-cyclohexanone aqinise isikhundla sayo emkhakheni wezingubo nopende. Incibilikisa ngempumelelo ama-resins, ama-cellulose esters, kanye nama-polymer ahlukahlukene, ithuthukisa ukugeleza, ukulinganisa, kanye nezakhiwo zokomisa zezakhiwo zokugqoka—okwenza kube yisithako esisetshenziswa kakhulu sezingubo zokugqoka zezimboni, ukuqeda ukhuni, kanye nopende wokuhlobisa. Idatha yemakethe ikhombisa ukuthi isidingo esivela embonini yezingubo zokugqoka sikhule kancane kancane, ikakhulukazi emazweni asafufusa lapho ukuthuthukiswa kwengqalasizinda kanye nokuhlala kwamadolobha kuqhuba ukusetshenziswa okuphezulu kwezingubo zokwakha nezezimboni.
Izimboni zemithi kanye nezibulala-zinambuzane nazo zinegalelo ekudingweni kwe-cyclohexanone, njengoba isebenza njengesihluthulelo esiyinhloko ekuhlanganisweni kwezithako ezithile zemithi ezisebenzayo (ama-API) kanye namakhemikhali ezolimo. Ngaphezu kwalokho, indima yayo ekusetshenzisweni kabusha kwerabha kanye nokucubungula ipulasitiki—lapho isiza khona ekuthambiseni nasekuguquleni izinto zerabha kanye nepulasitiki—iye yanda eminyakeni yamuva nje, ihambisana nemikhuba yomhlaba wonke yemikhuba yomnotho ojikelezayo.
Ngokombono wokuhlinzeka, izifunda ezinkulu zokukhiqiza ziyaqhubeka nokwenza ngcono izinqubo zokukhiqiza ukuze zilinganisele ukusebenza kahle kanye nokusimama. Intuthuko kwezobuchwepheshe be-catalytic oxidation yokukhiqizwa kwe-cyclohexanone ayithuthukisanga nje amazinga okukhiqiza kodwa futhi inciphise ukusetshenziswa kwamandla kanye nomthelela wezemvelo, ibhekana nokukhathazeka okukhulayo emhlabeni jikelele mayelana nezinyathelo zekhabhoni ekukhiqizweni kwamakhemikhali.
Uma sibheka phambili, ochwepheshe bemboni balindele ukuthi isidingo se-cyclohexanone sizohlala siqinile. Ukwanda okuqhubekayo kwemakethe ye-nylon, kanye nezidingo ezikhulayo ezivela emikhakheni yokukhiqiza yamakhemikhali akhethekile kanye neyoluhlaza, kulindeleke ukuthi kusekele ukukhula okuqhubekayo. Okwamanje, ukuguquguquka kwezindleko zezinto zokusetshenziswa kanye nokuguquguquka kweketanga lokuhlinzekwa kwesifunda kungabangela izinselele zesikhashana, kodwa umbono wesikhathi eside walesi sikhemikhali esiguquguqukayo uhlala umuhle, uqhutshwa yindima yaso engenakuphikiswa ezinkethweni ezibalulekile zenani lezimboni.
