【摘要】 氘代乙醛（ Ｃ Ｄ３ Ｃ Ｄ Ｏ）是合成惯性约束聚变（ Ｉ Ｃ Ｆ）固体靶材料氘代聚苯乙烯（ Ｄ Ｐ Ｓ）的重要中间体之一。以电石（ Ｃａ Ｃ２）及重水（ Ｄ２ Ｏ）为原料，经多步液固、气液化学反应，合成氘代率达９９２ ％的氘代乙醛。介绍了氘代乙醛的合成工艺及其氘代率的表征方法，并对主要合成工艺参数等进行了探讨。更多还原

【Abstract】 Perdeuterated acetaldehyde is one of the intermediates for the synthesis of perdeuterated polystyrene which is the material of inertial confinement fusion (ICF) solid targets. Calcium carbide and heavy water are used as the main reactants, through a series of liquid solid and gas liquid reactions, perdeuterated acetaldehyde (the deuterium isotopic content is more than 99 %) has been synthesized. This paper describes the synthesis procedures and deuterium isotopic content characterization method,some of the process parameters have been discussed also.更多还原
