Description

General description

Tetrahydrofuran-d₈ (THF-d₈), a deuterated derivative of tetrahydrofuran, is a standard purity solvent suitable for routine NMR analyses (conducted at ambient temperatures where quality is less critical). It participates as a solvent in an intermolecular proton exchange reaction between methanol and acetic acid. Kinetics of this reaction has been studied by ′H NMR line shape analysis. Infrared spectral studies of THF and THF-d₈ have been investigated in the range of 10 and 300cm^-1.

Tetrahydrofuran-d₈ may be used as a solvent in the synthesis of deuteriotris[bis(trimethylsilyl)amido]thorium and deuteriotris[bis(trimethylsiiyl)amido]uranium.
