    摘要： The present invention provides a process, which includes: contacting at least one C4-hydrocarbon stream which includes isobutene with methanol over at least one acid catalyst and preparing methyl tert-butyl ether (MTBE) and a substantially isobutene-free C4-hydrocarbon mixture; wherein in a first stage in one or more first reactors, the isobutene reacts with the methanol over an acid catalyst to form an equilibrium mixture which includes MTBE, remaining isobutene and methanol; the equilibrium mixture is fed to a second stage which includes a reactive distillation column; and in the reactive distillation column, the remaining isobutene reacts with methanol over an acid ion exchange resin to form MTBE; wherein the reactive distillation column is operated at a pressure ranging from 3 to 15 bar abs., a reaction zone temperature ranging from 55° C. to 75° C., and a reflux ratio of less than 1. The present invention also provides a method of making gasoline, which includes the above process and contacting the MTBE with a fuel.

    摘要： The invention is a method for processing a mixture containing water, 3-methyl-1-butene and at least one other methylbutene. The method comprises primary distillation of the mixture, giving a gaseous primary overhead product containing methylbutene and water and a water-free primary bottom product containing 3-methyl-1-butene; condensation of the gaseous primary overhead product so as to give a condensate comprising a liquid aqueous phase and a liquid organic phase; separation of the condensate into a liquid aqueous phase and a liquid organic phase; discharge of the liquid aqueous phase; recirculation of the organic phase to the primary distillation; and finally secondary distillation of the water-free primary bottom product from the primary distillation so as to give a secondary overhead product comprising 3-methyl-1-butene and a secondary bottom product. The secondary overhead product obtained has a purity which enables it to be used directly as monomer or comonomer for preparing polymers or copolymers.
