摘要: A process for the synthesis of zirconium tetra carboxylates is disclosed. To overcome the disadvantageous characteristics of the currently used production process, which include highly corrosive starting substances and products, and complex removal of HCl, ZrCI4 is suspended in an apolar solvent and reacted with the anhydride of an organic acid. The sole products of this reaction are slightly corrosive Zr tetra carboxylate and an organic 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.
