Abstract
A process for production of dialkyl ether by hydration and etherification of olefinic feedstock containing at least one lower alkene by contacting the olefinic feedstock and water in a catalytic reaction zone with porous solid metallosilicate acidic catalyst under olefin hydration and etherification conditions. Improvement is achieved by recovering a first fluid effluent stream from the reaction zone; splitting the first fluid effluent stream into a liquid product recovery stream and a fluid recycle stream; and passing the fluid recycle stream consisting essentially of olefin, alcohol and ether in effluent stream proportions for feeding to the reaction zone along with fresh olefinic feedstock and fresh water, wherein the amount of fluid recycle stream is sufficient to maintain a homogeneous single fluid reaction phase in the reaction zone.
