摘要： Isobutene is prepared by dissociating tert-butanol into isobutene and water over an acid ion-exchange resin arranged as a fixed bed in at least one reactor at a temperature of from 80 to 150° C. and at a pressure of from 5 to 25 bar to obtain a reaction mixture, separating the reaction mixture into isobutene, a by-product, water and at least one mixture of undissociated tert-butanol and water. The reactor is operated pseudo-isothermally, with a temperature difference between inflowing and outflowing streams of less than 15 K.

摘要： Polluted groundwater is purified by separating off solids and adsorbing dissolved organic compounds to an adsorber resin. The adsorbed organic compounds are desorbed using steam and the adsorber resin is regenerated using an acid and an oxygen-containing gas. The process makes it possible to separate aromatic and halogenated hydrocarbons off of heavily polluted groundwater to the extent that the groundwater can be added to flowing surface water without reservation. The purified water can, if appropriate, be used as cooling water, or after further biological purification, as drinking water.
