Abstract

Isopropyl alcohol and diisopropyl ether are continuously made by passing a mixture of propylene and water, isopropyl alcohol or a mixture thereof at 275-315 DEG F. and a pressure of 250 to 1500 p.s.i.g. through a bed of a granular catalyst composed of a cross-linked, water-insoluble sulphonated polystyrene resin, and separating the reaction products from unconverted reagents. Preferably the catalyst is a sulphonated resinous copolymer of 80 to 95 per cent by weight of styrene and 20 to 5 per cent of p-divinyl-benzene. The feed mixture may contain, for example, 0.3 to 15 mols. of water, isopropyl alcohol or a mixture thereof per mol. of propylene. If the alcohol is the required product water should be used whereas if the ether is desired isopropyl alcohol is used. If water is used it is desirable that 4 to 10 mols. of water per mol. should be used whereas if isopropyl alcohol is used it is desirable that 0.3 to 5 mols. per mol. of propylene be used plus, optionally, up to 0.5 mols. of water. Feed rates may range from 0.5 to 10 liquid volumes of total feed per volume of catalyst per hour, the higher rates favouring alcohol production. The hydrocarbon feed may be essentially pure propylene or C3 fractions containing 30 to 50 mol. per cent of propylene. In the examples: (a) a hydrocarbon feed consisting of 50 per cent propylene and 5 per cent propane is mixed with water and passed through a bed of granular sulphonated styrene-divinylbenzene resin to give isopropanol with a small amount of di-isopropyl ether; (b) a hydrocarbon feed consisting of 50 per cent propylene and 50 per cent propane is mixed with aqueous isopropyl alcohol and passed through a bed of granulated sulphonated polystyrene catalyst to give diisopropyl ether and some isopropyl alcohol which is recycled.
