摘要

摘要采用有机合成方法制备了纯丙二醛。第一步，丙二醛钠盐经1,1,3,3-四甲基氧基丙烷酸水解得到，甲醇/醚重结晶纯化。第二步，丙二醛钠盐与溶解在乙醚中的气态盐酸在- 40℃下反应合成丙二醛。最后，丙二醛在低于0°C的温度下通过泵送提纯，并通过升华提取。

Malonaldehyde Synthesis

Abstract Pure malonaldehyde is obtained by organic synthesis. In the first step, malonaldehyde sodium salt is obtained by 1,1,3,3-tetramethoxypropane acidic hydrolysis and purified by recrystallization in methanol/ether. In the second step, malonaldehyde is synthesized by reaction between malonaldehyde sodium salt and gaseous hydrochloric acid dissolved in ether at − 40 °C. Finally, malonaldehyde is purified by pumping at temperatures less than 0 °C and extracted by sublimation.

期刊介绍： Synthetic Communications presents communications describing new methods, reagents, and other synthetic work pertaining to organic chemistry with sufficient experimental detail to permit reported reactions to be repeated by a chemist reasonably skilled in the art. In addition, the Journal features short, focused review articles discussing topics within its remit of synthetic organic chemistry.
