    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： The isomerization of C.sub.5 /C.sub.6 n-paraffins to isoparaffins, comprises:a stage (1) of deisopentanizing a charge constituted by a light naphtha,a stage (2) of isomerizing the deisopentanization residue, an adsorption stage (3) carried out by passing the isomerization effluent onto an adsorbent retaining the n-paraffins and alternating with the adsorption stage (3), a desorption stage (4) carried out by lowering the pressure and stripping by means of an isopentane-rich gas flow from the deisopentanization stage.The isomerate freed from the n-paraffins in stage (3) is a product having a high octane number.

    摘要： For co-production of metaxylene and paraxylene from a feedstock (line-4) of hydrocarbons, there is employed a simulated moving bed chromatographic column 5 having at least five zones and which delivers an extract, a raffinate and an intermediate raffinate. The feedstock has an ethylbenzene content of less than 5% by weight, and the chromatographic column comprises at least twenty-five beds, of which at least five beds are in zone 3B. The raffinate is distilled (31) to recover the metaxylene at a purity of at least 99% and orthoxylene. The extract is distilled (7, 10) to recover the paraxylene at a purity of at least 99.6%. The recovered isomers can be synthesized into isophthalic acid and terephthalic acid.
