文摘

It was shown in this work that the clathrate hydrates of Hexagonal Structure III, formed in the ternary systems 1-methylpiperazine-help gas-water and iso-amyl alcohol-help gas-water are stable in a wide range of pressures. The decomposition curves of these hydrates were studied for the first time up to the pressures 1 GPa. Ar, Kr, Xe and CHb>4b> were utilized as the help gases. In a number of the systems studied, high pressure phases were revealed that presumably form due to the distortion of the corresponding low pressure hydrate structures.
