辛酸亚锡制备

以脂肪族羧酸盐和锡的盐类或氧化物为原料，进行合成制得；也可用有机酸酐和锡的氧化物合成。
（1）氯化亚锡的预处理　在装有机械搅拌、温度计、回流冷凝器的三口烧瓶中加入氯化亚锡、少量锡粒和浓盐酸，加热到135～140℃，回流约90min后，加水稀释到1.2mol/L，备用。
（2）氧化亚锡的制备　搅拌下将2.5mol/L的氢氧化钠水溶液滴入预处理毕的氯化亚锡水溶液中，即有白色固体生成。控制反应液最终pH值为8～9，煮沸约20min后，白色固体转化为褐色固体———无水氧化亚锡，过滤，沸水洗涤数次，即得成品。
（3）辛酸亚锡的制备　在装有机械搅拌、温度计、回流冷凝器的500mL三口烧瓶中，加入200mL异辛酸和63.4g氧化亚锡，在氮气保护下，搅拌加热到140℃，反应90min后过滤除去未反应的氧化亚锡，再减压蒸馏除去水和未反应的异辛酸，得辛酸亚锡。
