Method for one-step method synthesis of stripping hydrotalcite/ hydrotalcite like compound

一种一步法合成剥离水滑石/类水滑石的方法

Abstract

本发明提供了一步法合成剥离水滑石/类水滑石的方法,采用以下步骤:将可溶性二价金属盐和可溶性三价金属盐以及尿素加入到盛放有双氧水溶液的三口烧瓶中,所述的可溶性二价金属盐和可溶性三价金属盐的摩尔比为2:1~5:1,所述的双氧水溶液的质量浓度为1%~30%,将溶液机械搅拌5~30min,将搅拌后的溶液升温至120~150℃,并在此温度下搅拌、冷凝回流反应5~12h,将反应产物过滤并洗涤后干燥处理,即制得剥离水滑石/类水滑石。本发明提供的方法不仅能够在开放体系中安全、简单、高效率的合成,而且可以通过控制双氧水的浓度来调控产品的形貌。
The invention provides a method for one-step method synthesis of stripping hydrotalcite/ hydrotalcite like compound, and the method comprises the following steps: adding a soluble divalent metal salt, a soluble trivalent metal salt and urea to a three mouth flask containing a hydrogen peroxide solution, wherein the mole ratio of soluble divalent metal salt to soluble trivalent metal salt being 2:1 ~ 5:1, and the mass concentration of the hydrogen peroxide solution being 1% ~ 30%; mechanically stirring the solution for 5 ~ 30min, heating the stirred solution to 120 ~ 150 DEG C, stirring for reflux condensation reaction for 5 ~ 12h at 120 ~ 150 DEG C, and filtering, washing and drying a reaction product to obtain the stripping hydrotalcite/ hydrotalcite like compound. The method can be used for safe, simple and efficient synthesis in an open system, and can control the morphology of a product by controlling the concentration of the hydrogen peroxide solution.
