설명

일반 설명

3-Pentanone is a 3-alkanone. It undergoes deprotonation on reaction with lithium diisopropylamide (LDA) in THF (solvent) to afford E enolate while the same reaction in THF/HMPT (HMPT = hexamethylphosphoric triamide, THF = tetrahydrofuran) solvent system affords Z enolate. It is widely used as a tracer for planar laser-induced fluorescence (PLIF) studies. Its electron-diffraction patterns and fluorescence quantum yields have been evaluated.
3-Pentanone is a diethyl ketone, which can be obtained as a major product of the condensation of propanol over ceria-zirconia mixed oxides catalyst, Ce_xZr_1-xO₂.

애플리케이션

3-Pentanone may be used to evaluate excess molar volumes of its binary mixtures with 1-chloroalkanes at 298.15K and atmospheric pressure.
