Abstract
The article presents the synthesis of several cyclic alcohol sulfosuccinates and the study results of their influence on the kineticsof methane hydrate formation in high-pressure autoclaves. The effect of the structure of the tested compounds on foaming, induction time, and water-to-hydrate conversion is considered in comparison with sodium dodecyl sulfate. The process of obtaining the substances used is presented in detail. It was found that an increase in the size of the cycloalkyl fragment from C5 to C7 leads to some acceleration of the nucleation and growth of methane hydrate. In contrast, the transition to a cycle containing eight carbon atoms decreasesthe promoting effect. It is shown that the impact of the synthesized compounds on accelerating the formation of gas hydratesis comparable to that for sodium dodecyl sulfate. At the same time, the proposed reagents possess better performance characteristics (do not contribute to foaming).
