    摘要： The formation of hydrocarbon hydrates can be inhibited or mitigated by contacting a a mixture comprising water and hydrate-forming guest molecules under gas hydrate forming conditions with a quaternary ammonium hydroxide QOH or a quaternary ammonium compound QA, in which A is not a halogen atom. The QOH or QA may be prepared reacting a quaternary ammonium halide QX with a metal hydroxide M(OH)x, or with a metal salt MA, in an alcohol solvent to form a quaternary ammonium hydroxide QOH, or a quaternary ammonium compound of formula QA, and metal halide MX. Optionally, the quaternary ammonium hydroxide QOH may be reacted with an organic or inorganic acid AH which is different from a hydrogen halide to form the quaternary ammonium compound QA. The metal halide MX may be removed by phase separation after addition of water or of a water/solvent mixture, or by filtration.
