摘要:
This process for the manufacture of isobutyric anhydride by reacting acetic anhydride with isobutyric acid, distilling the acetic acid generated as it is formed, is characterized in that the reactor is initially loaded with at least a portion of one of the reagents and a portion of the other such that the reagents are in an excess molar ratio relative to the stoichiometry of one of the reagents, and the reaction is carried out while adding the remainder of the reagents as the reaction progresses and according to the place left free in the reactor by the distillation of the acetic acid produced by the reaction, until the desired overall molar ratio of the reagents is reached.

用于通过使乙酸酐与异丁酸反应制备异丁酸酐的方法,蒸馏生成的乙酸,其特征在于反应器最初装载有至少一部分试剂和一部分试剂 其它使得试剂相对于一种试剂的化学计量为过量的摩尔比,并且当反应进行时加入其余试剂并根据反应器中剩余的位置由反应器中的位置进行反应 蒸馏通过反应产生的乙酸,直到达到所需试剂的总摩尔比。
