    • PURPOSE: Provided is a separation method of methyl pyrazine from an aqueous solution by introducing an entrainer instead of applying salting-out separation method, thereby increasing separation efficiency. CONSTITUTION: The separation method of methyl pyrazine from an aqueous solution obtained from the dehydration-dehydrogenation of 1,2-propylene glycol and ethylene amine is characterized by selectively using an entrainer instead of salting-out separation method which involves anhydrous soda as a salting-out agent. Therefore, the separation efficiency of methyl pyrazine from water can be increased.
    • 目的:提供通过引入夹带剂而不是施加盐析分离方法从水溶液中分离甲基吡嗪的分离方法,从而提高分离效率。 构成:从1,2-丙二醇和乙烯胺的脱水脱氢得到的水溶液中甲基吡嗪的分离方法的特征在于选择性地使用夹带剂代替盐析分离方法,该方法涉及无水苏打作为盐析 - 代理人 因此,甲基吡嗪从水中的分离效率可以提高。

    • PURPOSE: Provided is a process for regenerating an iron-palladium solid catalyst by an air-calcinating, the iron-palladium solid catalyst is used in a process for preparing cyclohexanol and cyclohexanone by a selective oxidation of cyclohexane. CONSTITUTION: The process for regenerating the iron-palladium solid catalyst comprises the steps of: recovering the iron-palladium solid catalyst from the process of the selective oxidation of the cyclohexane; precalcinating the used iron-palladium solid catalyst under a hydrogen atmosphere at a temperature of 100 to 150 °C; air-calcinating the precalcinated iron-palladium solid catalyst at a temperature of 100 to 150 °C.
    • 目的:提供通过空气煅烧再生铁 - 钯固体催化剂的方法,铁 - 钯固体催化剂用于通过选择性氧化环己烷制备环己醇和环己酮的方法。 构成:再生铁 - 钯固体催化剂的方法包括以下步骤:从环己烷的选择性氧化过程中回收铁 - 钯固体催化剂; 在氢气氛下,在100〜150℃的温度下,预先使用铁 - 钯固体催化剂; 在100〜150℃的温度下对煅烧后的铁 - 钯固体催化剂进行空气煅烧。
