Abstract
A low temperature, low pressure process for the production of alcohol by the hydration of olefins. The olefin is contacted with a sulfonated ion-exchange resin in the presence of water and glycol diethyl solvent to hydrate said olefin, preferably propylene, and form from the olefin the corresponding aliphatic, monohydric alcohol. The solvent, a key and novel feature of the invention, at reaction conditions forms two liquid phases, a glycol diether phase and a water phase. The alcohol forms predominanty in the glycol diether phase and to a lesser extent in the water phase, with the products, inclusive of by product either, being distributed between the two phases. The glycol diethyl phase effectively displaces the equilibrium toward higher alcohol production, and the ether by product suppresses the equilibrium and minimizes formation of the ether product.
