Abstract
This invention concerns a process and an apparatus for producing ether and the use of a dimerised reaction product as the olefinic feedstock in etherification. According to the present process alcohol and C.sub.8-C.sub.12 olefin(s) are fed to a first reaction zone (21-25) comprising at least one reactor, the olefin(s) and alcohol are subjected to an etherification reaction in the presence of an acidic catalyst. The effluent from the first reaction zone (21-25) is fed to a fractionation zone (26). From the fractionation zone (26) is withdrawn a side-flow which is conducted either back to the first reaction zone (21-25) or to a second reaction zone. The effluent of the first reaction zone (21-25) or the second reaction zone is circulated back to the fractionation zone (26), and the ether is recovered from the fractionation zone (26).
