Method for the preparation of dialkyl ethers.

摘要

A method for producing dialkyl ethers comprising feeding a stream containing a C1 to C4 alcohol to a distillation column reactor into a feed zone, contacting the stream with a fixed bed zeolite prepared as a distillation structure to form the corresponding dialkyl ether and water, and concurrently fractionating the ether product from the water and unreacted materials wherein the improvement is the addition of a small amount of hydrogen to the reaction zone to inhibit catalyst fouling and substantially increasing the catalyst life and activity.
