    • Described are diester amine adducts of formula (1) wherein R1, R2, R3, R4 are each independently of one another C4-C22alkyl; C2-C22alkenyl; or C5-C7cycloalkyl; X1 and X2 are each independently of the other hydrogen, C1-C4alkyl; C2-C4hydroxyalkyl or C2-C4hydroxyhaloalkyl; Y is a radical of formula (1b); A1 is C2-C3alkylene or 2-hydroxy-n-propylene; X3 is hydrogen; C1-C4alkyl, C2-C4hydroxyalkyl; or C2-C4hydroxyhaloalkyl; (A) is an asymmetrical carbon atom in the R- or S-configuration, wherein, if C1=R, C2=R; C1=S, C2=S; and C1=R; C2=S; m1 is 1 or 2; and n is an integer from 1 to 4; p is 0 or 1; which adducts may be in the form of free bases or ammonium salts. Said compounds are precursors of compounds having good complex-forming properties and are thus able to effectively bind heavy metal ions such as iron, zinc, magnesium or copper ions and to prevent metal-initiated oxidations after enzymatic or chemical cleavage. They have a plurality of uses, for example in foods, beverages, derusting and decalcification baths, as additives in liquids for cooling-water circuits, in personal-care products, as bleaching stabilizers, in cleaning agents and detergents, in the textile industry and also as soft handle agents for organic fibre materials.
    • 描述了式(1)的二酯加合物,其中R 1,R 2,R 3,R 4各自独立地为C 1 -C 22烷基; C 2 -C 22烯基; 或C 5 -C 7环烷基; X 1和X 2各自独立地为另一个氢,C 1 -C 4烷基; C 2 -C 4羟烷基或C 2 -C 4羟基卤代烷基; Y是式(1b)的基团; A1是C2-C3亚烷基或2-羟基 - 正丙烯; X3是氢; C 1 -C 4烷基,C 2 -C 4羟烷基; 或C 2 -C 4羟基卤代烷基; (A)是R-或S-构型中的不对称碳原子,其中如果C1 = R,则C2 = R; C1 = S,C2 = S; 和C1 = R; C2 = S; m1为1或2; n为1〜4的整数。 p为0或1; 哪些加成物可以是游离碱或铵盐的形式。 所述化合物是具有良好的络合物形成性质的化合物的前体,因此能够有效地结合重金属离子如铁,锌,镁或铜离子,并且在酶或化学裂解后防止金属引发的氧化。 它们具有多种用途,例如在食品,饮料,除锈和脱钙浴中,作为用于冷却水回路的液体,个人护理产品中的添加剂,漂白稳定剂,清洁剂和洗涤剂在纺织工业中的用途,以及 也作为有机纤维材料的软处理剂。
