Comparison of the nuclear magnetic resonance and infrared spectroscopic methods for the quantitative analysis of polydimethylsiloxane

Autor: I. K. O'neill, H. J. Prosser, M. A. Pringuer

Publikováno v: The Journal of pharmacy and pharmacology. 27(4)

A method based on nuclear magnetic resonance spectroscopy is described for the quantitative determination of polydimethylsiloxane (PMS) in a variety of pharmaceutical preparations. An extraction procedure using deuterochloroform within the sample tub

Quantitative13C NMR analysis of mixtures of 2,4-di-isocyanatotoluene and 2,6-di-isocyanatotoluene

Autor: I. K. O'Neill, M. A. Pringuer

Publikováno v: Organic Magnetic Resonance. 6:398-399

Some isomeric mixtures, such as the toluene di-iso-cyanates, may be quantitatively analysed by measurement of peak heights of a 13C FT-NMR spectrum without the use of gated decoupling or the addition of paramagnetics.
