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９９２ ％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。
Deuteroacetaldehyde (C D3 C D O) is one of the important intermediates in the synthesis of deuterated polystyrene (D P S), a solid target material for the synthesis of inertial confinement fusion (I C F). Calcium hydroxide (Ca C2) and heavy water (D2 O) as raw materials, the multi-step liquid solid, gas liquid chemical reactions, the synthesis of deuterated acetaldehyde deacidification rate of 99 2%. The synthesis process of deuterated acetaldehyde and its deuteration rate were introduced, and the main synthetic process parameters were also discussed.
