研究了常压下甲醇脱氢制甲酸甲酯的膜催化反应．采用离子交换法制备的铜复合膜在１６０～２６０℃表现出较高的反应活性，２４０℃时甲醇转化率和甲酸甲酯收率分别为５７３％和５００％，而相应固定床反应器的甲醇转化率和甲酸甲酯收率分别为４３１％和３６９％．铜钯复合膜反应器能使反应选择分离同时进行，但产物甲酸甲酯的总收率不及铜复合膜．还对铜复合膜的制备条件作了初步探讨． Membrane catalysis of methanol dehydrogenation to methyl formate at atmospheric pressure was studied. The copper composite membranes prepared by ion exchange showed high reactivity at 160-260 ℃. The methanol conversion and methyl formate yield were 573% and 500% respectively at 240 ℃, while the corresponding fixed bed The methanol conversion and methyl formate yield of the reactor were 431% and 369%, respectively. Copper  palladium composite membrane reactor reaction-selective separation can be carried out simultaneously, but the total yield of methyl formate than the copper composite membrane. The preparation conditions of copper composite film were also discussed.
