Qhov sib txawv ntawm qhov sib sib zog nqus eutectic cov kuab tshuaj thiab cov kua ionic yog qhov sib sib zog nqus eutectic cov kuab tshuaj yog tsim los ntawm Lewis los yog Bronsted acids thiab hauv paus, whereas ionic kua tsim los ntawm tej ntsev.
Ob qhov sib sib zog nqus eutectic cov kuab tshuaj thiab cov kua ionic yog cov kua hauv cov dej sib xyaw uas peb tuaj yeem soj ntsuam ob qho tib si cations thiab anions. Ob lub xeev ionic no txawv ntawm ib leeg raws li lub hauv paus ntawm ions uas ua rau cov khoom sib tov.
Dab tsi yog Deep Eutectic Solvents?
Cov kuab tshuaj sib sib zog nqus eutectic yog cov khoom sib xyaw tsim los ntawm Lewis lossis Bronsted acids thiab cov hauv paus. Cov no yog cov kuab tshuaj eutectic, lub ntsiab lus homogenous sib xyaw ntawm cov khoom uas tuaj yeem yaj los yog khov ntawm ib qho kub (Qhov kub no feem ntau qis dua qhov melting point ntawm ib qho ntawm cov khoom hauv qhov sib tov). Feem ntau, cov kuab tshuaj sib sib zog nqus eutectic muaj ntau hom anionic thiab cationic hom.
Ntau hom Deep Eutectic Solvents
Muaj ntau hom sib sib zog nqus eutectic kuab tshuaj uas peb categorize raws li ionic hnyav zog uas yog tshwj xeeb rau cov kuab tshuaj. Thawj tiam ntawm cov kuab tshuaj no yog qhov sib xyaw ntawm quaternary ammonium ntsev. Cov kuab tshuaj no muaj cov neeg pub nyiaj hydrogen, xws li. amines thiab carboxylic acids. Peb tuaj yeem txheeb xyuas 4 hom sib sib zog nqus eutectic hnyav: hom I, hom II, hom III, thiab hom IV. Ntawm cov plaub hom no, hom I tob eutectic cov kuab tshuaj muaj quaternary ammonium ntsev nrog rau cov hlau chloride. Yog li, cov kuab tshuaj no kuj suav nrog ntau yam chlorometallate ionic kua. Hom II sib sib zog nqus eutectic cov kuab tshuaj muaj cov hlau chloride hydrate nrog rau quaternary ammonium ntsev. Qhov thib peb yog hom III sib sib zog nqus eutectic hnyav, qhov twg muaj quaternary ammonium ntsev nrog rau cov nyiaj pub dawb hydrogen. Thaum kawg, hom IV sib sib zog nqus eutectic cov kuab tshuaj muaj hlau chloride hydrate thiab hydrogen daim ntawv cog lus pub dawb (tsis muaj quaternary ammonium ntsev). Cov hom kev sib sib zog nqus eutectic cov kuab tshuaj no yog qhov tseem ceeb vim tias cov kuab tshuaj no tuaj yeem tsim cov cationic hlau complexes, uas ua kom ob txheej nyob ze rau ntawm electrode nto uas muaj cov hlau ion concentration.
Piv rau cov organic tebchaw tsis muaj zog, cov kuab tshuaj sib sib zog nqus muaj qhov vapor siab heev. Yog li ntawd, cov kuab tshuaj no feem ntau yog flammable. Ntxiv mus, cov kuab tshuaj no muaj viscosity siab uas tuaj yeem cuam tshuam kev lag luam siv vim tias cov kuab tshuaj no yuav tsis yooj yim ntws hauv cov txheej txheem ntws.
Ionic Liquids yog dab tsi?
Ionic kua yog ntsev hauv lub xeev ua kua. Feem ntau, cov kua ionic feem ntau yog ua los ntawm ions tshwj tsis yog rau qee cov kua dej ionic xws li dej, uas muaj cov hluav taws xob tsis zoo. Muaj qee qhov sib txawv ntawm cov kua ionic, uas suav nrog cov kua electrolytes, ionic melts, ionic kua, fused ntsev, kua ntsev, thiab ionic iav.
Muaj ntau daim ntawv thov ntawm cov kua ionic, uas suav nrog siv lawv ua cov kuab tshuaj muaj zog thiab ua electrolytes. Cov hom kua dej no muaj txiaj ntsig zoo hauv kev tsim cov roj teeb hluav taws xob thiab tseem muaj txiaj ntsig zoo hauv kev tsim cov sealant vim tias qhov vapor siab tsawg heev.
Cov ntsev uas tuaj yeem ua rau yaj yam tsis muaj decomposition lossis vaporization feem ntau muab cov kua ionic. Hauv qhov sib piv, thaum peb txias cov kua ionic, peb tuaj yeem tau txais cov khoom ionic uas yog crystalline lossis glassy. Qhov no tshwm sim vim yog lub zog ntawm ionic bonds hauv ionic solids / kua, uas ua rau cov kua ionic kom muaj zog lattice siab.
Dab tsi yog qhov zoo sib xws ntawm Deep Eutectic Solvents thiab Ionic Liquids?
- Deep eutectic solvents thiab ionic kua yog kua xeev.
- Ob leeg yog sib xyaw ntawm anions thiab cations.
Qhov txawv ntawm Deep Eutectic Solvents thiab Ionic Liquids yog dab tsi?
Ob qhov sib sib zog nqus eutectic cov kuab tshuaj thiab cov kua ionic yog cov kua hauv cov dej sib xyaw uas peb tuaj yeem soj ntsuam ob qho tib si cations thiab anions. Qhov sib txawv ntawm qhov sib sib zog nqus eutectic kuab tshuaj thiab cov kua ionic yog qhov sib sib zog nqus eutectic cov kuab tshuaj yog tsim los ntawm Lewis los yog Bronsted acids thiab cov hauv paus, whereas ionic kua tsim los ntawm tej ntsev.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm qhov sib sib zog nqus eutectic cov kuab tshuaj thiab cov kua ionic.
Summary – Deep Eutectic Solvents vs Ionic Liquids
Ob qhov sib sib zog nqus eutectic cov kuab tshuaj thiab cov kua ionic yog cov kua hauv cov dej sib xyaw uas peb tuaj yeem soj ntsuam ob qho tib si cations thiab anions. Qhov sib txawv ntawm qhov sib sib zog nqus eutectic kuab tshuaj thiab cov kua ionic yog qhov sib sib zog nqus eutectic cov kuab tshuaj yog tsim los ntawm Lewis los yog Bronsted acids thiab cov hauv paus, whereas ionic kua tsim los ntawm tej ntsev.
