Do ion tethered functional groups affect IL solvent properties? The case of sulfoxides and sulfones

The covalent incorporation of functional groups - specifically sulfoxide and sulfone - into the cation of imidazolium ionic liquids leads to significant, quantifiable changes in solvent parameters which in turn have important effects on the bulk properties of the materials. The Royal Society of Chemistry 2006.

METHOD FOR THE PRODUCTION OF (METH)ACRYLIC ESTERS

The present invention relates to a process for preparing (meth)acrylates, comprising the transesterification of a low-boiling ester of (meth)acrylic acid with a reactant alcohol in the presence of catalysts, which is characterized in that the transesterification is catalysed by a basic ion exchanger.

Impact of ionic liquid physical properties on lipase activity and stability

Lipase activity and stability was investigated in dialkylimidazolium and pyrrolidinium-based ionic liquids with a variety of anions including hexafluorophosphate, acetate, nitrate, methanesulfonate, trifluoroacetate, and trifluoromethylsulfonate. The initial rate of lipase-catalyzed transesterification of methyl methacrylate in these ionic liquids and several organic solvents was examined as well as the polytransesterification of divinyl adipate and 1,4-butanediol. Free lipase (Candida rugosa) catalyzed the transesterification of methyl methacrylate in 1-butyl-3-methylimidazolium hexafluorophosphate at a rate 1.5 times greater than in hexane. However, no detectable activity was observed in all the hydrophilic ionic liquids studied. Methods of enzyme stabilization including adsorption, PEG-modification, and immobilization in polyurethane foam were ineffective in improving enzymatic activity in the hydrophilic ionic liquids. Polytransesterifications performed in 1-butyl-3-methylimidazolium hexafluorophosphate using Novozym 435 produced polyesters with weight average molecular weights limited to 2900 Da due to precipitation of the polymer. Solvatochromic studies and partition coefficient measurements suggest that ionic liquids are more polar and hydrophilic than organic solvents such as hexane, acetonitrile, and tetrahydrofuran. Stability studies indicate that lipases exhibit greater stability in ionic liquids than in organic solvents including hexane.
