<p>Light olefins are catalytically converted to ethers, e.g., propylene is converted to diisopropyl ether, in a two stage process in which product ether is recycled to a first stage reaction zone to significantly reduce the operating temperature of the olefin hydration/etherification reactions taking place in that zone. Alcohol produced in the first stage reaction zone undergoes conversion in the second stage reaction zone, e.g., by catalytic distillation, to provide additional product ether.</p> |
