摘要： Conventional regenerative adsorptive methods for the purification of waters of organic constituents are limited in their application, when owing to a low content of organic water constituents the loading of the adsorbers is so low that the condensed water vapor desorbate no longer has a tendency to form two phases, or when the organic components are readily water-soluble and thus, following desorption with water vapor, can be separated only with difficulty out of the condensed desorbate. The process of the invention improves the tendency toward phase separation by cycling back the aqueous phase of the desorbate onto a loaded adsorber prior to its desorption in order to increase the loading and reduce, through additional supply of external heat, the required amount of water vapor for desorption. The present process is particularly useful for purification of industrial process waters or ground water.

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.

摘要： A process for the removal of ethers and/or PAH's from water, such as contaminated groundwater, is provided that proceeds by initially separating off solid constituents and then adsorbing ethers and polycyclic aromatic hydrocarbons to an adsorber resin, then, as needed, desorbing the adsorbed compounds with steam and regenerating the adsorber resin with an acid, to provide purification of highly polluted groundwater to such a substantial extent that the groundwater can be added to flowing surface waters without problem, and, if desired, used as cooling water or, after further biological purification, as drinking water.

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： The invention describes a process for preparing acetone starting from acetyl-coenzyme A comprising process steps A. enzymatic conversion of acetyl-CoA into acetoacetyl-CoA B. enzymatic conversion of acetoacetyl-CoA into acetoacetate and CoA and C. decarboxylation of acetoacetate to acetone and CO2, which is characterized in that the coenzyme A is not transferred in process step B to an acceptor molecule. In addition, process step B is surprisingly catalyzed by enzymes of the classes of acyl-CoA thioesterase, acyl-CoA synthetase or acyl-CoA thiokinase.A completely novel metabolic pathway is concerned, because the enzymatic hydrolysis of acetoacetyl-CoA without simultaneous transfer of CoA to a receptor molecule has never previously been described for any microbial enzyme.
