摘要： The present invention relates to a method for preparing linear alpha-olefins (LAO) by oligomerization of ethylene in the presence of solvent and homogenous catalyst, comprising the steps of: (i) feeding ethylene, solvent and catalyst into an oligomerization reactor, (ii) oligomerizing the ethylene in the reactor, (iii) removing a reactor outlet stream comprising solvent, linear alpha-olefins, ethylene, and catalyst from the reactor via a reactor outlet piping system, (iv) transferring the reactor outlet stream to a catalyst deactivation and removal step, and (v) deactivating and removing the catalyst from the reactor outlet stream, characterized in that at least one organic amine is added into the oligomerization reactor and/or into the reactor outlet piping system.

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.
