Indawo yokubilisa ye-cyclohexane: uhlalutyo olunzulu kunye nezicelo
I-Cyclohexane iyikhompawundi ebalulekileyo esetyenziswa ngokubanzi kwishishini lemichiza kunye neempawu zayo ezibonakalayo zinempembelelo enkulu kwimveliso yemveliso. Phakathi kwabo, indawo yokubilisa ye-cyclohexane yiparameter ephambili, ebalulekileyo kuyilo kunye nokuphucula iinkqubo ezininzi. Kulo phepha, indawo yokubilisa ye-cyclohexane iya kuhlalutywa ngokubanzi, kwaye ubudlelwane bayo kunye nezinye izinto kunye nokubaluleka kwayo kwizicelo eziphathekayo ziya kuxoxwa.
Ulwazi olusisiseko kwindawo yokubilisa ye-cyclohexane
I-Cyclohexane yi-saturated cyclic hydrocarbon ene-chemical formula C6H12. Indawo yokubilisa kwayo kuxinzelelo lwe-atmospheric yi-80.74 ° C. Eli qondo lobushushu lisezantsi ngokwentelekiso lenza kube lula ukulawula ukutshintshwa kwesigaba phakathi kolwelo kunye negesi ye-cyclohexane. Le propati ibaluleke kakhulu kwimveliso yeekhemikhali, ngakumbi xa iinkqubo ezifana ne-distillation kunye nokwahlula kubandakanyeka. Ukuqonda indawo yokubilisa ye-cyclohexane kunokunceda ukwenza ngcono izixhobo zokusebenza kunye neemeko zokusebenza kwiinkqubo ezinxulumeneyo.
Ubudlelwane phakathi kwendawo yokubilisa kunye nesakhiwo semolekyuli ye-cyclohexane
Indawo yokubilisa ye-cyclohexane ichaphazeleka kakhulu kwisakhiwo sayo se-molecular. I-molecule ye-Cyclohexane inee-athom ze-carbon ezintandathu kunye ne-athom ye-hydrogen ezilishumi elinambini, ebonisa isakhiwo se-ring hexagonal esizinzileyo. Ngenxa yokuba kukho amandla e-van der Waals kuphela phakathi kweemolekyuli, i-cyclohexane inendawo yokubila esezantsi kuneemolekyuli ezininzi zepolar. Xa kuthelekiswa neekhompawundi zayo ezifanayo ngokwesakhiwo, indalo ye-cyclohexane ye-nonpolar iphumela kwindawo yokubila esezantsi kunobunzima obufanayo bealkanes tyeyini elithe ngqo. Ngoko ke, indawo yokubilisa ye-cyclohexane iba yinto ekufuneka ithathelwe ingqalelo xa usenza ukhetho lwe-solvent okanye ukusetha iimeko zokuphendula.
Ukubaluleka kwendawo yokubilisa ye-cyclohexane kwizicelo zoshishino
Indawo yokubilisa ye-cyclohexane idlala indima ebalulekileyo kwiinkqubo ezahlukeneyo zeekhemikhali. Ngokomzekelo, kwiinkqubo ze-petrochemical hydro-refining, i-cyclohexane idla ngokusetyenziswa njenge-solvent okanye ephakathi, kwaye ulwazi lwendawo yokubilisa lunokunceda ukwandisa ubushushu bokuphendula kunye neemeko zoxinzelelo. Kwi-high performance liquid chromatography (HPLC), i-cyclohexane idla ngokusetyenziswa njengenxalenye yesigaba esihambayo ngenxa yendawo yokubilisa ephantsi kunye nokunyibilika okulungileyo, ukuqinisekisa ukuba i-solvent ikhupha ngokukhawuleza ngaphandle kokuphazamisa inkqubo yokwahlula.
Iingqwalasela zokusiNgqongileyo kunye noKhuseleko kwiNdawo yokuBilisa yeCyclohexane
Enyanisweni, ulwazi lwendawo yokubilisa ye-cyclohexane nayo ibalulekile kwimveliso ekhuselekileyo. Ngenxa yeqondo eliphantsi lokubilisa kunye nokuguquguquka, ngakumbi kumaqondo okushisa aphezulu, i-cyclohexane idinga ingqalelo ekhethekileyo ukulawula ukuxinwa kwayo komphunga ukwenzela ukukhusela ukuqhuma okanye umlilo. Inkqubo efanelekileyo yokungenisa umoya kufuneka ifakwe kwisityalo kunye nezixhobo ezifanelekileyo zokubona ukuqinisekisa ukuba umphunga we-cyclohexane awugqithisi umda wokhuseleko.
Isishwankathelo
Indawo yokubilisa ye-cyclohexane yiparameter ebalulekileyo engakwazi ukunyanzeliswa kwimveliso yeekhemikhali kunye nemisebenzi yokulinga. Ukuqonda okucacileyo kwendawo yokubilisa kwayo kwenza uyilo olungcono lwenkqubo kunye nokuphucula, kwaye kunceda ukuqinisekisa ukhuseleko kwinkqubo yokuvelisa. Kwizicelo zeekhemikhali ezizayo, kunye nenkqubela phambili eqhubekayo yeteknoloji, uphando kunye nokuqonda indawo yokubilisa ye-cyclohexane iya kuba nzulu ngakumbi, ukukhuthaza ukuveliswa kwemveliso yeekhemikhali ngokufanelekileyo kunye nokukhuselekileyo.
