摘要： A catalyst for the carbonylation of dimethyl ether to methyl acetate. The catalyst comprises a zeolite, such as a mordenite zeolite, at least one Group IB metal, such as copper, and/or at least one Group VIII metal, such as iron, and at least one Group IIB metal, such as zinc. Such a catalyst with combined metals provides enhanced catalytic activity, improved stability, and improved selectivity to methyl acetate, and does not require a halogen promoter, as compared to a metal-free or copper only zeolite.

摘要翻译： 用于将二甲醚羰基化成乙酸甲酯的催化剂。 催化剂包括沸石，例如丝光沸石，至少一种IB族金属如铜，和/或至少一种第Ⅷ族金属，如铁，和至少一种IIB族金属，如锌。 与无金属或仅含铜的沸石相比，这种具有组合金属的催化剂提供增强的催化活性，改进的稳定性和对乙酸甲酯的改善的选择性，并且不需要卤素促进剂。
