Enzymatic Polymerization of Phenols in Room Temperature Ionic Liquids.
Soybean peroxidase (SBP) was used to catalyze the polymerization of phenols in room-temperature ionic liquids (RTILs). Phenolic polymers with number average molecular weights ranging from 1200 to 4100 D were obtained depending on the composition of the reaction medium and the nature of the phenol. Specifically, SBP was highly active in methylimidazolium-containing RTILs, including 1-butyl-3-met...
متن کاملRoom Temperature Ionic Liquids
The initial objective of this project was to carry out a fundamental study of the transport characteristics of a variety of gases and organic solutes in room temperature ionic liquids. The goal was to combine information collected from a number of different experimental measurements in order to develop a fundamental understanding of the interactions governing transport in ionic liquids. Measure...
متن کاملDynamic Heterogeneity in Room-Temperature Ionic Liquids
Room temperature ionic liquids (RTILs) are comprised of bulky organic cations and anions (Holbrey & Seddon, 1999; Weingärtner, 2008). Because of the intricate interplay of various interand intramolecular interactions, RTILs have rich dynamical properties and have found diverse applications. In particular, negligible vapor pressure of RTILs makes them a green alternative of conventional organic ...
متن کاملRuthenium(III) chloride catalyzed acylation of alcohols, phenols, and thiols in room temperature ionic liquids.
Ruthenium(III) chloride-catalyzed acylation of a variety of alcohols, phenols, and thiols was achieved in high yields under mild conditions (room temperature) in the ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF(6)]). The ionic liquid and ruthenium catalyst can be recycled at least 10 times. Our system not only solves the basic problem of ruthenium catalyst reuse, but ...
متن کاملElectrochemical Applications of Room - Temperature Ionic Liquids
R3 R2 There is good evidence that the first room-temperature ionic liquid or RTIL was identified and characterized by Walden in 1914, who examined the electrical conductivity of ethylammonium nitrate.1 Thus, it would not be an exaggeration to say that the very beginnings of electrochemistry involved room-temperature ionic liquids! Although once considered to be a curious subset of the general c...
