The present invention relates to a mixture comprising diesters of the formula (I) where R1 to R8═H or alkyl group having from 1 to 6 carbon atoms, where the R1 to R8 radicals may be the same or different, which is characterized in that at least two different diesters I are present in the mixture, said diesters differing in the structure of at least one of the carboxylic acid radicals C8H17COO present, to a process for preparing diesters of an isosorbide derivative of the formula I, in which a hexahydric alcohol and/or a monoanhydro or dianhydro derivative of the alcohol is esterified with a mixture of at least two different carboxylic acids of the empirical formula C8H17COOH, and to the use of these mixtures in paints, inks or coatings, in plastisols, adhesives or adhesive components, in sealants, as plasticizers in polymers or polymer components, as solvents, as lubricant oil components and as assistants in metal processing, and also PVC compositions or plastisols comprising PVC and from 5 to 250 parts by mass of the mixture per 100 parts by mass of PVC.
本发明涉及一种混合物,其中包括式(I)的二酯,其中R1到R8═H或具有1至6个碳原子的烷基,其中R1到R8基团可以相同也可以不同,其特征在于至少存在两种不同的二酯I在混合物中,所述二酯在C8H17COO羧基中的至少一个结构不同,以制备式I的异山梨醇衍生物的二酯的方法为特征,其中通过将六羟基醇和/或醇的单缩水或双缩水衍生物与至少两种不同的经验式为C8H17COOH的羧酸混合物酯化,以及在涂料、油墨或涂层中使用这些混合物,在塑料溶胶、粘合剂或粘合剂组分中使用这些混合物,在密封剂中使用这些混合物,在聚合物或聚合物组分中作为增塑剂,在溶剂中使用这些混合物,在润滑油组分中使用这些混合物以及在金属加工助剂中使用这些混合物,还包括PVC组合物或PVC溶胶,其中每100份PVC中含有5至250份混合物。
