Catalytic dehydration of methanol

The catalytic dehydration of methanol (ME) to form dimethyl ether (DME) and water was earried out over an ion exehange eatalyst [K. Klusacek, Collection Czech. Chem. Commun.,49, 170(1984)]. The packed bed was initially filled with nitrogen and at r = 0 a feed of pure methanol vapor entered the reactor at 413 K, 100 kPa, and 0.2 cmVs. The following partial pressures were recorded at the exit to the differentialreaetor containing 1.0 g of catalyst in 4.5 cm of reactor volume.
