    摘要： A process for the preparation of a tertiary alkyl ether, in particular methyl tert. amyl ether (MTAE), is described which comprises reacting, in a reaction section, a charge constituted by a mixture of C.sub.5 hydrocarbons, including reactive isopentenes, with an aliphatic monoalcohol in excess, such as methanol, ethanol, propanol or isopropanol, and collecting in the bottom of a fractionation section the corresponding pure tert. alkyl ether. The head effluent, after condensation, is subdivided into a liquid reflux and a distillate. The process is further characterized by providing a finishing reactor for the reflux, or for the reflux + distillate effluent prior to the subdivision thereof, or two finishing reactors are provided, one for the reflux and the other for the distillate, along with the possibility of injecting aliphatic monoalcohol upstream of each finishing reactor.

    摘要： 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.

    摘要： An enhanced ether production process from an olefinic cut containing at least one iso-olefin and from an alcohol comprises a stage of removal of the acetonitrile present in the hydrocarbon feed by liquid-liquid extraction, the extraction solvent being a non-aqueous ionic liquid of general formula Q+A−, wherein Q+ is an ammonium, phosphonium and/or sulfonium cation, and A− an anion likely to form a liquid salt with said cation. Advantageously, the method according to the invention generally allows the amount of water at the etherification reactor inlet to be divided by at least two and thus the purity of the ether produced to be improved.

    摘要： A process for carrying out a reaction on an organic feed, for example dimerization, co-dimerization, oligomerization or metathesis of olefins, as described in which the catalyst is a catalytic metal compound dissolved in a non-aqueous ionic medium which is not or is only slightly miscible with hydrocarbons. The reaction is carried out in a system comprising at least two treatment loops each comprising at least one reaction zone and at least one zone for separating the organic and polar phases between which the polar medium containing the catalytic metal compound, and the organic phase circulate. Fresh polar phase is injected into the second loop and used polar phase is eliminated from the first loop. The hydrocarbon to be transformed is injected into the first loop and the products are withdrawn from the second loop. The invention also concerns a unit for carrying out the process.
