Uhlalutyo olunzulu lweNdawo yokuBilisa ye-Triethylamine
I-Triethylamine (i-TEA ngokufutshane) yinto eqhelekileyo ye-organic compound eyeyeklasi ye-amine yeekhemikhali. Isetyenziswa kakhulu kumashishini amaninzi afana namayeza, izibulali zinambuzane, idayi, izinyibilikisi njalo njalo. Njengekhemikhali esetyenziswa ngokuqhelekileyo, iimpawu ezibonakalayo ze-Triethylamine, ngokukodwa indawo yokubilisa, iiparamitha ezifuna ukuqondwa ngokuchanekileyo kwaye zilawulwe kwiinkqubo ezininzi zeekhemikhali. Kweli phepha, siza kuxubusha inqaku lokubilisa le-triethylamine ngokweenkcukacha, sihlalutye izizathu ze-physicochemical emva kwayo, kunye nokubaluleka kwayo kwizicelo eziphathekayo.
Isishwankathelo sendawo yokubilisa ye-triethylamine
Indawo yokubila ye-triethylamine yi-89.5 ° C (193.1 ° F), iqondo lokushisa elibilisayo kuxinzelelo oluqhelekileyo lwe-atmospheric (1 atm). Iqondo lokubila liqondo lobushushu apho uxinzelelo lomphunga lolwelo lulingana noxinzelelo lwangaphandle, okuthetha ukuba kobu bushushu butshintsha i-triethylamine ukusuka kulwelo ukuya kwimeko yegesi. Iqondo lokubilisa liyipropathi ebalulekileyo ebonakalayo yento kwaye ibalulekile ekuqondeni ukuziphatha kwe-triethylamine phantsi kweemeko ezahlukeneyo.
Izinto ezichaphazela indawo yokubilisa ye-triethylamine
Indawo yokubilisa ye-triethylamine ichaphazeleka kakhulu yisakhiwo sayo se-molecular kunye ne-intermolecular forces. I-Triethylamine yi-amine ye-tertiary ene-molecular structure ine-athomu ye-nitrogen edityaniswe kumaqela amathathu e-ethyl. Ngenxa yokuba kukho iperi enye kuphela yee-electron kwi-athomu yenitrogen kwi-triethylamine molekyuli, akukho lula kwi-triethylamine ukwenza iibhondi ze-hydrogen. Oku kwenza amandla e-intermolecular ye-triethylamine ikakhulu amandla e-van der Waals, abuthathaka kakhulu. Ngenxa yoko, indawo yokubilisa ye-triethylamine iphantsi.
Amatyathanga e-hydrocarbon kwi-molecule ye-triethylamine ayi-hydrophobic, ekwanefuthe kwindawo yayo yokubilisa. I-Triethylamine inobunzima obuphakathi bemolekyuli xa kuthelekiswa nezinye i-amine eziphilayo ezifanayo, ezichaza ngokuyinxenye indawo yayo ephantsi yokubilisa. Ukuhlanganiswa kwesakhiwo se-molecular kunye ne-intermolecular forces ye-triethylamine imisela indawo yayo yokubilisa ye-89.5 ° C. Indawo yokubilisa ye-triethylamine nayo ingumsebenzi wesakhiwo semolekyuli ye-amine.
Ukubaluleka kwendawo yokubilisa ye-triethylamine kwizicelo zoshishino
Kubalulekile ukuqonda nokulawula indawo yokubilisa ye-triethylamine kwinkqubo yokuvelisa imichiza. Ekubeni indawo yokubilisa ye-triethylamine isondele kwi-90 ° C, ukuhlukana okusebenzayo kunye nokucocwa kwe-triethylamine kunokufezekiswa ngokulungelelanisa ubushushu ngexesha lokuphendula kunye nenkqubo yokuhlukana. Ngokomzekelo, ngexesha lokuxutywa kwe-distillation, ukulawula ngokuchanekileyo iqondo lokushisa kufuphi nendawo yokubilisa ye-triethylamine kunokuyahlula ngokufanelekileyo kwezinye iikhompawundi ezinamazinga ahlukeneyo abilayo. Ukwazi indawo ebilayo ye-triethylamine kukwabalulekile ekusebenzeni ngokukhuselekileyo ukuthintela ilahleko eguquguqukayo engeyomfuneko okanye iingozi zokhuseleko ngenxa yobushushu obugqithisileyo.
Ukuqukumbela
I-Triethylamine ineqondo lokubila elingu-89.5°C. Le propati yomzimba imiselwe yi-molecular structure kunye ne-intermolecular forces. Kwishishini lemichiza, ulawulo oluchanekileyo lwendawo yokubilisa ye-triethylamine lubalulekile kwimveliso kunye nokhuseleko. Ukuqonda indawo yokubilisa ye-triethylamine ayincedi kuphela ukunyusa inkqubo yokuvelisa, kodwa inika isikhokelo esibalulekileyo kwimisebenzi ebonakalayo.
