摘要:

Trimethylsilyl ethers are shown to give sharp p. m. r. signals at τ 9.8-9.9 and to have distinct chemical shifts. The technique is useful for determining the number of hydroxyl groups in a molecule. Because each trimethylsilyl group consists of nine protons strong signals are obtained from small amounts of sample. The method is thus suitable for analyzing eluates collected by gas-liquid chromatography.
