詳細

詳細

2-Butanone is a ketone. Physical properties of the solutions of 1-n-butyl-3-methylimidazolium tetrafluoroborate (ionic liquid) in various organic solvents (acetonitrile, dichloromethane, 2-butanone and N,N-dimethylformamide) has been studied. Viscosity and density of these mixtures were evaluated at 298.15K.

アプリケーション

2-Butanone (Methyl ethyl ketone) may be employed as solvent for the methylation agent [¹¹C]methyl trifluoromethanesulfonate ([¹¹C]CH₃OTf), during the completely automated radiosynthesis of 2-(4-N-[¹¹C]methylaminophenyl)-6-hydroxybenzothiazole ([¹¹C]PIB). It may be used in the synthesis of nanocontainer composed of 6 bowl-shaped cavitands. In the nanocontainer, cavitands were joined by 12 -CH=N-CH₂CH₂-N=CH- linkers.
