摘　　要：以二氧化锗为原料,通过还原、加成、水解获得了β-羧乙基锗倍半氧化物。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为0.5h;n(二氧化锗)∶n(浓盐酸)∶n(次亚磷酸钠)=1∶7.4∶1.4;加成反应时间1.5h。此工艺使产率达到69.7%。通过Ge-132的红外光谱对产品进行了鉴定。βcarboxyethyl organogermanium sesquioxide(Ge-132) was synthesized from germanium dioxide through deoxidization,addition,and hydrolysis. The optimum conditions of the synthesis of βcarboxyethyl organogermanium sesquioxide were obtained through orthogonal test: the time from beginning to adding sodium hypophosphite is 0.5 h; the molar ratio of Germanium dioxide, hydrochloric acid and sodium hypophosphite is 1∶7.4∶1.4; and the reaction time of addition is 1.5 h. The yield is 69.7%. IR spectra was also used to identify the product.
