A process for concurrently producing diisopropyl ether and isopropyl ethyl ether from water, ethanol from an independent source, and propylene, has been developed. The product mixture may be used as a high octane number booster due mainly to the presence of the diisopropyl ether and to a lesser extent, the isopropyl ethyl ether. Furthermore, the product mixture, upon blending with gasoline, incorporates a renewable resource into the gasoline since the isopropyl ethyl ether is produced from ethanol. Optionally, the product mixture may be passed through an acid removal zone to remove acid, if present, before being recycled or further processed. A portion of the product mixture is recycled to the reaction zone to increase the conversion of reactants to products. |
