摘要
研究了巴豆醛液相氧化合成巴豆酸的工艺条件 实验表明，巴豆醛与过氧乙酸摩尔比为１：１．３，醋酸锰用量为 ２．５％（相对于巴豆醛），过氧乙酸的浓度为１５％，１０℃温度下反应６ｈ，收率达到６０％以上．
Synthesis conditions of crotonic acid by liquid-phase oxidation of crotonaldehyde are studied. Ac- cording to the experimental results, when the molar ratio of crotonaldehyde to peroxyacetic acid is l: l. 3, the amount of Mn(OAc)2 based on crotona1dehyde is 2.5 %, the concentration of peroxyacetic acid solution is l5 %, the reaction temperature is l0℃, and the reaction time is 6h, the yield of product is over 60%.
