• 方法一:其制备方法是在催化剂磷酸三乙酯的存在下，使乙酸在700℃左右热裂解，脱水生成乙烯酮，净化的乙烯酮气体在吸收塔内二聚化生成双乙烯酮。若温度过高，已生成的双乙烯酮会发生高聚生成多聚乙烯酮，同时在乙酸热裂解过程中必须加入阻聚剂氨气以免乙烯酮分解。其工艺是乙酸经气化器(在约40 kPa下)气化，在乙酸蒸气中加入乙酸投料量的0.3％的磷酸三乙酯，然后经预热器加热至反应温度，迅速通过裂解

• 用途一:作为有机合成试剂,用于制备农药、
• 蒸气密度:2.9 (vs air)
• 方法二:工业上乙酸制取双烯酮，也可用丙酮、乙酐、乙酸酯为原料进行热分解。丙酮热分解法可用于小规模生产，这种方法由于副产甲烷，得到的乙烯酮气体的纯度低，同时要除去残留的丙酮也比较困难。冰醋酸在磷酸三乙酯存在下，于750-780℃裂解得乙烯酮，再于8-10℃聚合生成双乙烯酮。
