Abstract
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.
