Selected Brønsted acidic ionic liquids were tested as homogeneous catalysts for the dehydration of methanol to dimethyl ether. Ionic liquids incorporating an alkanesulfonic acid as a part of the cation, a complex acidic anion, A(2)H, or both, proved to be good catalysts for this process, providing high conversions and selectivities. Homogeneous catalysis in the liquid state represents a novel approach to dimethyl ether synthesis.
选择了一些布朗斯特酸性离子液体作为均相催化剂,用于甲醇脱水制二甲醚。含有烷磺酸作为阳离子一部分、复杂酸性阴离子A(2)H或两者的离子液体被证明是该过程的良好催化剂,提供了高转化率和选择性。液体状态下的均相催化为二甲醚合成提供了一种新方法。
