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.
描述了公式(1)中的二酯胺加合物,其中R1、R2、R3、R4各自独立地为C4-C22烷基;C2-C22烯基;或C5-C7环烷基;X1和X2各自独立地为氢、C1-C4烷基;C2-C4羟基烷基或C2-C4羟基卤代烷基;Y为公式(1b)的基团;A1为C2-C3烷基或2-羟基-n-丙烷基;X3为氢、C1-C4烷基、C2-C4羟基烷基;或C2-C4羟基卤代烷基;(A)为R-或S-构型的不对称碳原子,其中,如果C1=R,C2=R;C1=S,C2=S;和C1=R;C2=S;m1为1或2;n为1到4的整数;p为0或1;这些加合物可以是自由碱或铵盐的形式。所述化合物是具有良好络合性能的化合物的前体,因此能够有效地结合重金属离子,如铁、锌、镁或铜离子,并能够防止酶解或化学解离后金属引发的氧化反应。它们具有多种用途,例如在食品、饮料、除锈和脱钙浴中,作为冷却水循环液体的添加剂,在个人护理产品中,作为漂白稳定剂,在清洁剂和洗涤剂中,在纺织工业中,以及作为有机纤维材料的柔软处理剂。
