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.
