Metal salts of organic acids complexed with &bgr;-diketone compounds are multifunctional complexes useful in the formulation of stabilizers for halogenated resins. These complexes may be used jointly with other low toxicity intermediates, such as zinc or magnesium intermediates, to form effective stabilizers that are non-toxic and exhibit better performance than other known stabilizers, including those containing toxic heavy metals such as cadmium or lead. The complex is prepared utilizing a Claisen condensation reaction and precipitation with water and heptane.
与&bgr;-二酮化合物络合的有机酸
金属盐是一种多功能络合物,可用于配制卤化
树脂的稳定剂。这些络合物可与其他低毒性中间体(如
锌或
镁中间体)联合使用,形成无毒且性能优于其他已知稳定剂(包括含有
镉或
铅等有毒重
金属的稳定剂)的有效稳定剂。该复合物是利用克莱森缩合反应和
水及
庚烷沉淀制备的。
