描述

产品介绍 四分子乙醛的环状聚合物。 四聚乙醛在60-65℃保持数天后,大部分转变成三聚乙醛和乙醛,在酸存在下可分解成乙醛,用尿素、碳酸氢钠、氢氧化钾、碳酸钠等碱介质处理可担高其热稳定性3-16倍。
别名 低聚乙醛;2,4,6,8-四甲基-1,3,5,7-四氧杂环辛;密达;蜗牛敌;Acetaldehyde tetramer; 2,4,6,8-tetramethyl-1,3,5,7-tetroxocane; Aldehyde(meta) ; Metacetaldehyde
应用 四聚乙醛是一种神经毒物,对蛞蝓和蜗牛的毒杀途径和胃毒,其触杀作用比胃毒作用更强。用四聚乙醛取代剧霉的砷酸钙、巴黎绿等无机农药,在防治蜗牛和蛞蝓的危害方面起重要作用。
