Morteza Torabi was born in 1995 in Hamedan, Iran. He received his B.Sc. in Applied Chemistry (2017) and M.Sc. in Organic Chemistry (2019) from Bu-Ali Sina University under the supervision of Professor Mohammad Ali Zolfigol. He is currently working towards his Ph.D. under the supervision of Professor Mohammad Ali Zolfigol at Bu-Ali Sina University. His research interest is the design, synthesis ...
Imidazolium ionic liquids (ILs) exhibited a dramatic acceleration effect on the electron transfer from metal complexes such as (C(5)Me(5))(2)Fe(II) and (C(5)Me(5))(2)Co(II) to the oxygen molecule; this acceleration effect can be ascribed to the stabilization of the oxygen radical anions by coordinating with the acidic C2-H of imidazolium ILs.
A range of novel, moisture-stable, Lewis-acidic ionic liquids has been prepared by mixing appropriate molar ratios of MCl2 (M = Zn and/or Sn) and quaternary ammonium salts of formula [Me3NC2H4Y]Cl (Y = OH, Cl, OC(O)Me, OC(O)Ph); the influence of substituent Y and metal M on the physical properties of the melts has been investigated.
in recent years there has been a great deal of attention paid by researchers in investigating ionic liquids (ils) mainly due to the tremendous potential that ionic liquids have in reaction and separation technology. sonic speed is an important thermodynamic property of ionic liquids (ils) and always chosen as a source to determine other properties. a database for the sonic speed of pure ils cre...
Ionic liquids have been employed to deconstruct and fractionate lignocellulosic biomasses because of their capacity to dissolve cellulose. However, there is limited literature reporting the use of ionic liquids in biomass saccharification, which mostly involves the addition of acid or water that conceals the true action of ionic liquid in saccharification. This article assesses the performance ...
n-(diphenylphosphino)triethyl- and tributylammonium salts are introduced as easily prepared, cheap and stable ionic liquids that act as the condensing agent and media for the efficient esterification of acids with alcohols and phenols. this class of ionic liquids is immiscible with the ester products and thus allows simple and easy separation of the desired products from the reaction mixture.
Some mono and di imidazolium-based ionic liquids with dicyanamide were synthesized and characterized. The synthesis of these compoundes were done based on alkylation reaction of N-methylimidazole followed by anion exchange. The structure of novel ionic liquids were identified by using FT-IR, 1HNMR spectroscopies and elemental analysis. Among the synthesized ionic liquids, thermal properties of ...
