摘要： The invention relates to a novel process for the synthesis of zirconium carboxylates. In order to overcome the disadvantageous characteristics of the currently used production process (highly corrosive starting substances and products, complex removal of HCI), it is proposed to suspend ZrCI4 in an apolar solvent and react it with the anhydride of an acid. The sole products to arise are the slightly corrosive Zr carboxylate and an acid chloride, which is a valuable basic chemical in the chemicals and pharmaceuticals industry. The reactors required for the synthesis need not necessarily consist of glass and/or enamel, but may instead be manufactured from stainless steel, which is cheaper. Apparatuses for the removal and treatment of hydrochloric acid are not necessary.

摘要： The invention concerns a method and device for removing particles, in particular soot particles, from exhaust gases produced by internal-combustion engines. The invention calls for the particles to be electrostatically charged by an electrode (4). The particles or particle agglomerates are trapped by a fine-mesh metal filter (5). The conducting material (5a), preferably a sintered ferritic metal, of which the filter (5) is made can also be used as a collecting electrode. A high voltage (6) is applied (7, 10) to the electrodes. At intervals, preferably at regular intervals, an electric current is passed (11, 12) through the filter (5), causing the filter material (5a) to heat up to a temperature above the ignition temperature of the particles. The preferred shape of the filter surface is a cylinder, truncated cone and/or cone.

摘要： A process for flushing an oligomerization reactor is described, including flushing the oligomerization reactor with a flushing medium comprising C6 linear alpha olefins, C8 linear alpha olefins, C10 linear alpha olefins, or a combination including at least one of the foregoing, to provide a purge stream comprising the C6 linear alpha olefins, C8 linear alpha olefins, C10 linear alpha olefins, or a combination including at least one of the foregoing, and a polymer byproduct of an oligomerization reaction. A process for the oligomerization of an olefin is also described, wherein the process includes oligomerizing the olefin in the reactor to form a reaction product stream comprising linear alpha olefins, and subsequently flushing the oligomerization reactor according to the process disclosed herein.
