Description

General description

Acetone-d₆ (CD₃COCD₃, Hexadeuteroacetone) is the hexadeuterated form of acetone, in which all hydrogen atoms in acetone molecule have been replaced by deuterium (D) atoms. It is a standard purity solvent for NMR (Nuclear Magnetic Resonance) analyses. Absorption spectra of CD₃COCD₃ samples cooled in molecular jet (jet-cooled) have been evaluated in the range of 51000-54000cm^-1. Collision of its molecular ions with a perdeuterated surface (C₂₀D₄₁ SAu) was investigated by ion-surface collision spectroscopy. The Infrared and Raman spectra of acetone-d₆ have been analyzed. It undergoes H-²H exchange reaction with acetone d₀ to afford acetone d₁ and d₅.

Application

Acetone-d₆ may be used as a deuterated solvent in the ¹H NMR spectral studies of iodine containing radiopaque poly(methacrylate)copolymers. It may also be used as a source of deuterium atoms in the synthesis of labelled sterols.
