A method for inhibiting formation of hydrocarbon hydrates in mixtures of water and a hydrate-forming guest molecule involves adding an ion pair to the mixtures in an amount effective to inhibit formation of the hydrocarbon hydrates under conditions otherwise effective to form the hydrocarbon hydrates in the absence of the ion pair. In one non-limiting embodiment of the invention the ion pair includes a cationic component that may be a quaternary ammonium compound or an onium compound and a non-cationic counter-ion component that could be an anionic compound, a non-ionic compound and/or an amphoteric compound. Two specific, suitable non-cationic counter-ion components include sodium dodecyl sulfate and ammonium alkyl ether sulfate.
一种抑制在水和形成水合物的客体分子的混合物中形成碳氢化合物水合物的方法是在混合物中加入离子对,加入量应能有效地抑制碳氢化合物水合物的形成,否则在没有离子对的条件下会有效地形成碳氢化合物水合物。在本发明的一个非限制性实施方案中,离子对包括阳离子成分(可以是季铵化合物或鎓化合物)和非阳离子反离子成分(可以是阴离子化合物、非离子化合物和/或两性化合物)。两种特定的、合适的非阳离子反离子成分包括十二烷基硫酸钠和烷基醚硫酸铵。
