  The present invention relates a method of preparing an organic diester which comprises a first step (1) whom a diolefin and a peracid compound are allowed to react to synthesize a monoepoxide, a second step (2) wherein said synthesized monoepoxide is allowed to react with water and carboxylic acid and a third step (3) where the synthesized compounds are allowed to react with an acid anhydride. The present invention also relates to a method of preparing an organic diester wherein in the second step (2), the molar ratio of water and carboxylic acid added into monoepoxide is more than 2 and not more than 20, to an organic diester preparing method wherein monoepoxide is allowed to react with water in the second step (2) and to a method of preparing an organic diester wherein in the second step (2), water and carboxylic acid are removed from the synthesized product and recycled to be used again in said second step (2). The purpose of the present invention is to provide a method of preparing an organic diester having a good selectivity a producing few impurities and using diolefin as a starting material. In the second step (2), when water and carboxylic acid are recycled and used again, it is possible to reduce the load of dumping water and particularly, when 1, 3-butadiene is used as diolefin, acetic acid is used as carboxylic acid and acetic anhydride is used as an acid anhydride it is also possible to reduce the use amount of acetic acid.

  本发明涉及制备有机二酯的方法，包括第一步（1），在该步骤中，将二烯和过氧化物化合物反应以合成单环氧化物；第二步（2），在该步骤中，将合成的单环氧化物与水和羧酸反应；第三步（3），将合成的化合物与酸酐反应。本发明还涉及一种制备有机二酯的方法，其中在第二步（2）中，加入到单环氧化物中的水和羧酸的摩尔比大于2且不大于20；一种有机二酯制备方法，其中单环氧化物在第二步（2）中与水反应；以及一种制备有机二酯的方法，其中在第二步（2）中，从合成的产物中去除水和羧酸并回收以再次使用。本发明的目的是提供一种制备有机二酯的方法，该方法具有良好的选择性，产生少量杂质，并使用二烯作为起始材料。在第二步（2）中，当水和羧酸被回收并再次使用时，可以减少倾倒水的负担，特别是当1,3-丁二烯被用作二烯，乙酸被用作羧酸，乙酸酐被用作酸酐时，也可以减少乙酸的使用量。

  C4 olefins comprising cis- and trans-butene-2 and butene-1 may be oxidized to their corresponding mono- and diacetates in the presence of acetic acid and an olefin-' activated palladium catalyst under mild conditions. With this catalyst, and depending in part upon the solvent employed, as well as other operating conditions, the formation of linear allylic 1-acetates over the corresponding branched compounds can be favoured in order to increase the yield of the corresponding linear 1,4-diacetates. The latter, in turn, may then be converted, for example, to butanediol by known hydrogenation methods. In a similar manner, isobutylene may be converted to a dialcohol.

  由顺式和反式丁烯-2 和丁烯-1 组成的 C4 烯烃可在乙酸和烯烃活化钯催化剂存在下，在温和条件下氧化成相应的单乙酸酯和二乙酸酯。 使用这种催化剂，并部分取决于所使用的溶剂以及其他操作条件，可以更有利于形成线性烯丙基 1-乙酸酯，而不是相应的支链化合物，以增加相应的线性 1,4-二乙酸酯的产量。 然后，后者可以通过已知的氢化方法转化为丁二醇等。 异丁烯也可以通过类似的方法转化为二元醇。
