Abstract
A process for treating a feedstock containing olefins of 6 carbon atoms per molecule, said olefins being either potentially etherifiable or (directly) etherifiable, wherein isomerization of a portion of the potentially etherifiable olefins is accomplished in part in an isomerization zone, in the presence of an isomerization catalyst that makes it possible to obtain an isomerization effluent which comprises in part etherifiable olefins, and in that, in part, etherification is carried out, in the presence of an etherification catalyst and at least one alcohol that has 1 to 4 carbon atoms per molecule, of a portion of etherifiable olefins that are contained in the feedstock, in a first etherification zone, and in part etherification is carried out of a portion of etherifiable olefins that are contained in said isomerization effluent, in a second etherification zone, in the presence of an etherification catalyst and at least one alcohol that has 1 to 4 carbon atoms per molecule, to optimize the production of ethers.
