Abstract: Novel alkoxy titanium(IV)-chelates are used to modify printing inks based on nitrocellulose or other cellulose ester derivatives. The novel chelates comprise citric acid alkyl esters as chelate formers. They delay, as other titanium chelates do, the well-known catalytic effect of the titanium component in cross-linking reactions. When used in printing inks, the novel titanium chelates and their alcoholic solutions have the advantage that they have an insignificant color of their own, so that they practically do not discolor the printing inks. A further advantage of the novel chelates resides in that they do not enter into alteration effects with antioxidants based on phenol, so that they can also be used for printing inks which are to be applied to polymeric substrates containing such antioxidants without the occurence of discoloration.
Abstract translation: 新型烷氧基钛（IV） - 螯合物用于改性基于硝化纤维素或其它纤维素酯衍生物的印刷油墨。 新型螯合物包括柠檬酸烷基酯作为螯合物。 与其他钛螯合物一样，它们延迟钛组分在交联反应中的众所周知的催化作用。 当用于印刷油墨时，新型钛螯合物及其醇溶液的优点在于它们本身具有无色的颜色，因此它们实际上不会使印刷油墨变色。 新型螯合物的另一个优点在于它们不会以基于苯酚的抗氧化剂引起改变效果，因此它们也可以用于印刷油墨，这些油墨应用于含有这种抗氧化剂的聚合物基材上，而不发生变色。

Abstract: Organic titanium chelates which contain only acetylacetone and triethanolamine as ligands and chelating agents and are soluble in glycol ethers are disclosed. The addition of even a small amount of the glycol ether to these new substances improve the stability of their aqueous solutions in an extraordinary manner. Preferably, solutions of 50 to 80% of these new chelates are used, from which very dilute aqueous solutions, i.e., 1 to 5% of extraordinarily high stability can be made.

Abstract: Disclosed are new zirconic acid esters which contain glycol ether moieties as the ester grouping, and which are chelated with one and up to a maximum of two moles of acetylacetone. The new compounds can also contain up to a maximum of two moles of ester groupings of low alkanols. The new partially chelated zirconic acid esters are characterized by good solubility in water, in which they do not decompose at room temperature. Accordingly, they can also be used in aqueous systems as crosslinking agents or reaction accelerators.
Abstract translation: 公开了含有二醇醚部分作为酯基的新的锆酸酯，它们与1个和多达2个摩尔的乙酰丙酮螯合。 新化合物还可以含有最多2摩尔低级链烷醇的酯基。 新的部分螯合的锆酸酯的特征在于在水中具有良好的溶解性，其中它们在室温下不分解。 因此，它们也可用作水系统中的交联剂或反应促进剂。

Abstract: New titanium chelates containing triethanolamine as chelating agent, plus one or two glycol ether groups bound to the titanium atom are disclosed. Solutions of these new titanium chelates, pure or solved in glycol ether, can be diluted with water such that even 1% aqueous solutions are stable and show no turbidity or precipitation even after several weeks of standing. The new compounds are obtained by the reaction of the known triethanolamine titanates with glycol ethers, followed by distillation of the alcohol that forms, plus the alcohol serving as solvent, if any.
