Ukuhlaziywa Okuningiliziwe Kwephuzu Elibilisayo le-Triethylamine
I-Triethylamine (i-TEA ngamafuphi) iyinhlanganisela evamile ye-organic eyingxenye ye-amine yamakhemikhali. Isetshenziswa kabanzi ezimbonini eziningi ezifana nemithi, izibulala-zinambuzane, odayi, izinyibilikisi nokunye. Njengekhemikhali evame ukusetshenziswa, izici ezibonakalayo ze-Triethylamine, ikakhulukazi iphuzu layo elibilisayo, ziyimingcele edinga ukuqondwa ngokunembile futhi ilawulwe ezinkambisweni eziningi zamakhemikhali. Kuleli phepha, sizoxoxa ngephuzu elibilayo le-triethylamine ngokuningiliziwe, sihlaziye izizathu ze-physicochemical ngemuva kwalo, nokubaluleka kwalo ekusetshenzisweni okungokoqobo.
Uhlolojikelele lwephuzu lokubilisa le-triethylamine
Iphuzu elibilayo le-triethylamine lingu-89.5°C (193.1°F), okuyizinga lokushisa elibilayo elinomfutho womoya ojwayelekile (1 atm). Iphuzu elibilisayo izinga lokushisa lapho umfutho we-vapor woketshezi ulingana nokucindezela kwangaphandle, okusho ukuthi kuleli zinga lokushisa i-triethylamine iyashintsha isuka esimweni esiwuketshezi iye esimweni segesi. Iphuzu lokubilisa liyimpahla ebalulekile ebonakalayo yento futhi libalulekile ekuqondeni ukuziphatha kwe-triethylamine ngaphansi kwezimo ezihlukahlukene.
Izinto ezithinta indawo yokubilisa ye-triethylamine
Iphuzu elibilayo le-triethylamine lithonywa kakhulu ukwakheka kwamangqamuzana namandla e-intermolecular. I-Triethylamine iyi-amine ephakeme ukwakheka kwayo kwamangqamuzana aqukethe i-athomu ye-nitrogen exhunywe kumaqembu amathathu e-ethyl. Ngenxa yokuthi kunepheya elilodwa kuphela lama-electron ku-athomu ye-nitrogen ku-molecule ye-triethylamine, akulula nge-triethylamine ukwakha ibhondi ye-hydrogen. Lokhu kwenza amandla e-intermolecular e-triethylamine ikakhulukazi amandla e-van der Waals, abuthakathaka ngokuqhathaniswa. Ngenxa yalokho, iphuzu lokubilisa le-triethylamine liphansi kakhulu.
Amaketanga e-hydrocarbon ku-molecule ye-triethylamine ayi-hydrophobic ngandlela-thile, nayo enomthelela endaweni yayo yokubilisa. I-Triethylamine inesisindo esimaphakathi se-molecular uma iqhathaniswa namanye ama-amine aphilayo afanayo, achaza kancane iphuzu layo eliphansi lokubilisa. Inhlanganisela yesakhiwo samangqamuzana namandla e-intermolecular e-triethylamine inquma indawo yayo yokubilisa engu-89.5°C. Iphuzu elibilayo le-triethylamine liphinde libe umsebenzi wesakhiwo samangqamuzana e-amine.
Ukubaluleka kwephuzu lokubilisa le-triethylamine ekusetshenzisweni kwezimboni
Kubalulekile ukuqonda nokulawula iphuzu elibilisayo le-triethylamine ohlelweni lokukhiqiza amakhemikhali. Njengoba iphuzu lokubilisa le-triethylamine lisondele ku-90 ° C, ukuhlukaniswa okuphumelelayo nokuhlanzwa kwe-triethylamine kungafinyelelwa ngokulungisa izinga lokushisa ngesikhathi sokusabela kanye nenqubo yokuhlukanisa. Isibonelo, ngesikhathi sokukhishwa kwe-distillation, ukulawula ngokunembile izinga lokushisa eduze nendawo yokubilisa ye-triethylamine kungayihlukanisa ngokuphumelelayo kwezinye izinhlanganisela ezinamaphoyinti ahlukene abilayo. Ukwazi indawo yokubilisa ye-triethylamine nakho kubalulekile ekusebenzeni okuphephile ukuze kugwenywe ukulahlekelwa okuguquguqukayo okungadingekile noma izingozi zokuphepha ngenxa yamazinga okushisa angaphezu kwamandla.
Isiphetho
I-Triethylamine inephuzu lokubila elingu-89.5°C. Le mpahla ebonakalayo inqunywa isakhiwo sayo samangqamuzana namandla e-intermolecular. Embonini yamakhemikhali, ukulawulwa okunembile kwendawo yokubilisa ye-triethylamine kubalulekile ekukhiqizeni nasekuphepheni. Ukuqonda iphuzu lokubilisa le-triethylamine akusizi nje kuphela ukukhulisa inqubo yokukhiqiza, kodwa futhi kunikeza isiqondiso esibalulekile ekusebenzeni okungokoqobo.
