The effect of methanol on the stability of clathrate hydrates

Abstract

From the effect of added methanol on the decomposition temperatures of the clathrate hydrates of ethylene oxide and tetrahydrofuran, it was recently reported that methanol can be readily enclathrated in hydrates of both structure I and II. Dielectric and nmr studies of these two hydrates prepared in the presence of methanol do not support this conclusion. It is shown thermodynamically that the original measurements may be interpreted without the need for incorporation of methanol in the hydrates formed.
