Njenge-organic intermediate ebalulekile kanye ne-solvent esetshenziswa kabanzi embonini yamakhemikhali, i-cyclohexanone isetshenziswa kakhulu ezimbonini ezifana ne-resin, i-coating kanye ne-chemical fiber. Ngenxa yezici zayo zokusha, ukuguquguquka kanye nokucasuka, imibuzo ehlukahlukene ivame ukuvela ngesikhathi sokukhiqizwa kwayo, ukugcinwa kwayo, ukuthuthwa kwayo kanye nokusetshenziswa kwayo. Leli phepha lixazulula imibuzo yemboni evame kakhulu futhi linikeza izimpendulo zobungcweti ngokusekelwe ezimpahleni zomzimba nezamakhemikhali kanye nemininingwane yokuphepha, linikeza izinkomba ezisebenzayo kochwepheshe abafanele.
1. Izakhiwo Eziyisisekelo Zomzimba Nezamakhemikhali ze-Cyclohexanone
I-Cyclohexanone (CAS: 108-94-1) inefomula yama-molecule ye-C₆H₁₀O. Ngaphansi kokushisa okuvamile kanye nengcindezi, iwuketshezi olukhanyayo olungenambala kuya koluphuzi olukhanyayo olunephunga elimnandi elikhethekile elifana ne-mint ne-camphor, elicasula lapho liphezulu. Inemingcele eqinile yomzimba kanye neyamakhemikhali: iphuzu lokuncibilika elingu--45°C, iphuzu lokubila elingu-155.6°C, kanye nobuningi obungu-0.9478 g/cm³ ku-20°C. Njengoba ilula kunamanzi, izontanta phezu kwamanzi uma kwenzeka kuvuza. Incibilika kancane emanzini, i-cyclohexanone ixubana nezinyibilikisi eziningi eziphilayo ezifana ne-ethanol, i-ether kanye ne-benzene. Ngephuzu elikhanyayo lendebe elivaliwe elingu-46°C, ihlukaniswa njengoketshezi oluvuthayo lwe-Class B. Umhwamuko wayo ungakha ingxube eqhumayo nomoya, ngomkhawulo wokuqhuma wevolumu ongu-1.1%–9.4%. Ivame ukusha nokuqhuma uma ibhekene namalangabi avulekile, amazinga okushisa aphezulu kanye nama-oxidant anamandla.
2. Ukusetshenziswa Okuyinhloko kwe-Cyclohexanone
I-Cyclohexanone iyinto eluhlaza eyinhloko kubunjiniyela bamakhemikhali obuhle obunezimo eziningi zokusetshenziswa. Ukusetshenziswa kwayo okuyinhloko ukulungiselela i-caprolactam ne-adipic acid, ezicutshungulwa kabanzi ukuze kukhiqizwe i-nylon 6, i-nylon 66 kanye neminye imikhiqizo ye-fiber yamakhemikhali, okwenza kube yinto ebalulekile embonini ye-fiber yezindwangu namakhemikhali. Okwamanje, isebenza njengesinyibilikisi sezimboni esisebenza kahle kakhulu esinokuncibilika okunamandla kwezinto ze-polymer kufaka phakathi i-polyurethane, i-epoxy resin kanye ne-acrylic resin, futhi isetshenziswa kabanzi ekukhiqizeni izembozo, uyinki, izinamathiseli kanye nezinto zokuqeda isikhumba. Ngaphezu kwalokho, ingasetshenziswa ekulungiseleleni ama-antioxidants erabha, izithasiselo ze-organic synthesis kanye ne-intermediates yemithi, futhi ivame ukusetshenziswa ekucubungulweni kwepulasitiki nasekuhlanzweni kwensimbi.
3. Izingozi ze-Cyclohexanone empilweni yabantu
I-Cyclohexanone inobuthi futhi iyacasula, futhi ingangena emzimbeni womuntu ngokuphefumula, ukuthintana kwesikhumba kanye nokumunca ngomlomo. Ukuchayeka isikhathi eside ku-cyclohexanone enokuhlushwa okuncane kuzocasula ulwelwesi lwama-mucous lwamehlo, impumulo kanye nomphimbo, okubangela izimpawu ezifana nokuklebhuka, ukukhwehlela kanye nomphimbo owomile. Ukuthintana kwesikhumba isikhathi eside kuzolimaza ungqimba lwamafutha esikhumba, okuholela ekomeni, ekuqhekekeni, ekuqhekekeni kanye nase-contact dermatitis. Ukuphefumula umhwamuko oqukethe ukuhlushwa okuphezulu kuvimbela uhlelo lwezinzwa oluphakathi, okuholela ezimpawini zokubulala izinzwa ezifana nesiyezi, isicanucanu, ukukhathala nokuhlanza, kanti amacala amakhulu angase ahilele ukudideka, i-hypothermia kanye nokuthuthumela. Ukungenisa ngengozi kuzocasula indlela yokugaya ukudla futhi kulimaze imisebenzi yesibindi kanye nezinso. Ezimweni zomsebenzi, ukuhlushwa okuphezulu okuvunyelwe endaweni yokusebenza kulawulwa ngokuqinile ku-200 mg/m³.
4. Imininingwane Ejwayelekile Yokugcina Nokuthutha i-Cyclohexanone
Ukuze kugcinwe, i-cyclohexanone kufanele igcinwe endaweni yokugcina amakhemikhali ekhethekile epholile, eyomile futhi enomoya omuhle, kude nemithombo yomlilo kanye nemithombo yokushisa. Izinga lokushisa lendawo yokugcina akufanele lidlule ku-30°C, futhi ukukhanya kwelanga okuqondile akuvunyelwe. Izitsha kumele zivalwe kahle ukuze kuvinjelwe ukuguquguquka nokuvuza. Hlanganisa indawo yokugcina nama-oxidants, ama-acids aqinile kanye nezisekelo eziqinile akuvunyelwe. Indawo yokugcina kufanele ifakwe izibani ezingaqhumi, izindawo zokungenisa umoya kanye nezicishamlilo. Ukuze kuthuthwe, i-cyclohexanone kufanele ilethwe ngokuhambisana nezindinganiso zamakhemikhali ayingozi angoketshezi avuthayo. Izimoto zokuthutha kumele zibe nezitifiketi zokuthutha amakhemikhali ayingozi afanelekayo futhi zihlonyiswe ngamadivayisi alwa nama-static, imishini yokulwa nomlilo kanye nezinto zokuvikela eziphuthumayo. Ngesikhathi sokuthutha, ukuchayeka elangeni, ukushayisana okukhulu kanye nokushayisana kufanele kugwenywe. Hlanganisa ukuthutha nokudla nama-oxidants akuvunyelwe. Imisebenzi yokulayisha nokukhulula impahla kumele iphathwe ngobumnene ukuze kuvinjelwe ukuvuza.
5. Ukwelashwa Okuphuthumayo Kokuvuza Kwe-Cyclohexanone Nokuchayeka Ebantwini
Uma kwenzeka ukuthintana nesikhumba, susa izingubo ezingcolile ngokushesha bese ugeza isikhumba esithintekile kahle ngamanzi amaningi ahlanzekile agelezayo okungenani imizuzu eyi-15. Uma uthintana namehlo, vula amehlo bese uhlanza amehlo njalo ngamanzi ahlanzekile noma usawoti ojwayelekile ngaphambi kokufuna ukwelashwa ngesikhathi esifanele. Uma kwenzeka uphefumula, suka endaweni engcolile uye emoyeni omusha ngokushesha. Nikeza usizo lwe-oxygen ezinkingeni zokuphefumula, futhi wenze ukuphefumula okwenziwe ngokushesha ukuze uphefumule ngaphambi kokwelashwa. Uma kwenzeka ukuvuza, susa abasebenzi abangabalulekile ngokushesha, hlukanisa indawo evuzayo bese usika yonke imithombo yomlilo ukuze uvimbele amalangabi avulekile kanye nogesi ongashintshi. Ukuvuza endaweni encane kungamuncwa ngesihlabathi noma i-activated carbon. Uma kwenzeka ukuvuza okukhulu, yakha imisele yokuvimba, qoqa uketshezi oluvuzayo ukuze lubuyiselwe noma ulunikeze izikhungo zobungcweti ukuze zilahlwe. Ukukhishwa ngqo emanzini nasezindleleni zokuhambisa indle akuvunyelwe ngokuphelele.
6. Izinyathelo Zokuqapha Ngomsebenzi Wansuku Zonke We-Cyclohexanone
Abaqhubi kumele bathole ukuqeqeshwa kobungcweti futhi balandele ngokuqinile izimfuneko zokusebenza. Imishini yokuzivikela yomuntu siqu ehlanganisa izibuko, amagilavu enjoloba amelana ne-solvent kanye nezifihla-buso zegesi kumele zigqokwe kulo lonke umsebenzi. Indawo yokusebenza kumele igcine umoya ungena ngokuphelele, futhi ukubhema, ukudla nokuphuza akuvunyelwe ukuqeda izingozi zomlilo ezingaba khona. Yonke imishini yokukhiqiza kumele isebenze ivaliwe, futhi amapayipi nama-valve kufanele ahlolwe njalo ukuze kuvinjelwe ukuvuza. Ngemva komsebenzi, abaqhubi kumele bahlanze izandla nobuso kahle futhi bashintshe izingubo zomsebenzi, futhi akufanele bagqoke izingubo zomsebenzi ezingcolile ezindaweni zokuhlala. Ngaphezu kwalokho, izimpawu zesexwayiso kumele zibekwe endaweni yokusebenza, zihlonyiswe ngezindawo zokuhlanza eziphuthumayo kanye nemishini yokucima umlilo, futhi kufanele kwenziwe ukuvivinya okuphuthumayo njalo.
