  The present invention relates to an ionic liquid compound that inhibits a formation of a gas hydrate. The compound of the present invention changes an equilibrium temperature and pressure of a gas hydrate in small quantity into a lower temperature and/or a higher pressure, and simultaneously retards the formation of the gas hydrate under the same environment. Thus, the compound of the present invention is used in oil and natural gas industries to effectively inhibit or delay the formation of the gas hydrate under the condition having a low temperature and a high pressure.

  We report the concept of combining ionic liquids (ILs) with polymer inhibitors to more effectively inhibit methane hydrate formation. The new inhibitors extended the induction time and decreased the growth rate of the hydrate. It was found that the presence of a hydroxyl group on IL provided the most powerful inhibition effect by forming hydrogen bonds between IL and water molecules.

  我们报告了将离子液体 (IL) 与聚合物抑制剂相结合以更有效地抑制甲烷水合物形成的概念。新的抑制剂延长了诱导时间并降低了水合物的增长速度。研究发现，离子液体上羟基的存在通过在离子液体和水分子之间形成氢键，产生了最强大的抑制效果。
