ABSTRACT:
A water-free mixture of isopropyl alcohol, diisopropyl alcohol, diisopropyl ether and by-products is made by the catalytic hydration of propylene in the gaseous phase at temperatures of 140.degree.-170.degree.C under pressures of 25-40 atmospheres gauge. A water-to-propylene molar ratio of 0.1 to 0.25:1 is maintained in the hydration reaction. The crude product from the hydration reaction is dehydrated or dewatered in two columns without using a foreign withdrawing agent. Instead, diiosopropyl ether formed in the process itself is utilized as the withdrawing agent which is subsequently added to the water-free mixture together with additionally formed by-products. The water-free mixture formed according to the process can be used directly as an additive to gasoline fuel for motor vehicles.
