摘要： Integrated process for the production of ter-amyl alkyl ethers which comprises the feeding of a C.sub.5 hydrocarbon stream to an etherification reactor and the recycling of the remaining stream to the same reactor, after treatment in an isomerization section to convert linear pentenes into reactive isoamylenes. An absorption section on molecular sieves is inserted between the etherification reactor and the isomerization section to eliminate inert hydrocarbons, basically i-pentane and n-pentane.
