Cyclohexane: Chibelesyo chakupanga zintu antoomwe azibelesyo zyamakemikalu zyakupanga kabotu
Zibeela Zipati Zyakubelesya
Mumakwebo aamakemikalu, cyclohexane nchintu chibelesyegwa loko chikonzya kunyonyoona zintu zyiingi, zilimbuli ma resin, ma wax, mafuta, antoomwe a raba. Chiindi chiingi chibelesyegwa mukupanga raba, nsinga zyakupanga, azintu zyapulasitiki kugwasya kumwaya akunyonyoona zintu zipangwa, ikusumpula bubotu bwakupanga. Kuyungizya waawo, cyclohexane ibelesyegwa mbuli chintu chigwisya mukwaandaanya akusalazya zintu zipona, ikapati mumakemikalu mabotu amumisamu.
Mumakwebo aakuvwumba ama ingi, cyclohexane ibelesyegwa mbuli musamu uutanyonganyi busena nkaambo ulakonzya kunywika kabotu akuzungaana. Ilakonzya kufwambaana kunyonyoona zibeela zya resin zili muma coating amu ingi, mpawo kuvwuuma kwayo kuli akati-akati kulagwasya kupanga chivwumbyo chili kabotu, ikucheesya zisyango zya solvent. Bulowa busyoonto bwa cyclohexane bupa kuti itobelezye milawu miyumu yabusena, akupa kuti ibe nzila mbotu yakubelesya misamu iikola.
Mumakwebo aanunkilizyo azyakulya, tununkilizyo tulimbuli ether twa cyclohexane tupa kuti ube chintu chiyandikana loko. Chiindi chiingi chibelesegwa kusanganya mafuta aayandikana, mbuli mafwuta aa citrus, mint, alimwi atununkilizyo twamaluba, abelesyegwa kapati mumafuta aanunkilila, zintu zyakulisakatizya, alimwi azintu zipa kuti zyakulya zifwefweme. Kuyungizya waawo, cyclohexane ilakonzya kubelesegwa mbuli chintu chakuyungizya muzyakulya mukupanga maswiiti, zyakunywa, azintu zyakujika, ikuyungizya tununkilizyo twachilengwaleza kuzintu.
Mumakwebo aamisamu, cyclohexane ilakonzya kubelesegwa mbuli chintu chakusanzya akugwisya. ilakonzya kunyonyoona kabotu misamu iikola, ikugwasya kuti kube kusanduka kwamakemikalu akusalazya. Kuyungizya waawo, cyclohexane ilakonzya kubelesegwa mukubamba misamu, mbuli mafuta, makkilimu, ama suppositories, kugwasya misamu kuti imwaike akunjila kabotu.
Mumakwebo aa polymer, cyclohexane nchintu chiyandikana loko mukupanga nayiloni (polyamide). Ilasandulwa kuba cyclohexanol kwiinda mukubelesya nzila ya catalytic hydrogenation, eeyo mpawo isandulwa kuba adipic acid a caprolactam. Eezyi zintu nzintu ziyandisi kapati mukupanga nylon 6 a nylon 66. Nylon ilabelesyegwa kapati mumakwebo aazisani, myootokala, minchina, alimwi amakkampani akaambo kakuyuma kwayo, kutabola, alimwi akukazya kupya.

Mubufwaafwi
Alubo akusumpuka kwabusongo, nzila yakupanga cyclohexane ilazumanana kuyaambele. Kupanga cyclohexane kwamazubaano kubelesya nzila zibeleka kabotu zya catalytic hydrogenation kuchitila kuti kutabi kupanga zintu zimwi akusumpula kubelesya zintu. Kuyungizya waawo, kubelesya alimwi akubelesya alimwi musamu wa cyclohexane kuli mukucitwa, akucesya ntenda zyakwe kubusena.
Muchi chifwiifwi, cyclohexane, mbuli chintu chiyandikana loko chakupanga misamu, chilabelesyegwa munzila zyiingi mukupanga zintu. Tachigwasyi buyo kuchita obotu mukupanga zintu alubo chigwasya kukwabilila busena akusumpula zintu zitamani. Kakuli kuyaambele kwabusongo, nzila zyakubelesya cyclohexane ziyooba zipati.
