The optimum conditions to synthesizeβ-carboxyethyl organogermanium sesquioxide were established through orthogonal test: the time from beginning to adding sodium hypophosphite was 0.5h; the molar ratio of germanium dioxide, hydrochloric acid and sodium hypophosphite was 1:7.4:1.4; addition reaction time was 1.5h.

用正交试验确定了最佳工艺条件：从反应开始到加次亚磷酸钠的间隔时间0.5h；n：n：n=1 ： 7.4 ： 1.4；加成反应时间1.5h。

The thermodynamics and the dynamics mechanism have been studied.The results show that it is advisable for the HCHO and NaH_2PO_2 as the reduction due to the electrode potential of the reduction is more negative than that of Cu~ 2+ from the analysis of data in thermodynamics.It is advantage for the reaction of electroless copper in the alkaline solution. According to the analysis of Tafel slope of a cathodal polarization curve,...

结果表明：从热力学数据分析看，还原剂的电极电位皆比铜离子负，用甲醛、次亚磷酸钠做还原剂还原Cu2+在热力学上是可行的，在碱性溶液中对化学镀铜反应有利；从阴极极化曲线的Tafel斜率分析看，Cu2+=Cu+步骤为阴极反应的速度控制环节；从镀液的旋转圆盘电极测试结果分析看，电子跃迁步骤H2CO-ad rdsHCOOH+1/2H2+e-为镀液中阳极反应速度的控制性步骤。
