  The invention relates to a process for the preparation of adipic acid from adipic acid alkyl ester comprising: - subjecting an adipic acid alkyl ester to a hydrolysis reaction in the presence of water, at conditions of temperature and time suitable to form a hydrolysate comprising adipic acid; and - optionally recovering adipic acid from said hydrolysate, characterized in that the hydrolysis reaction is carried out in the initial presence of adipic acid, and further to adipic acid obtained by the process. The invention also relates to the use of adipic acid as an acid catalyst in the hydrolysis of adipic acid alkyl ester. The process may advantageously be carried out in the absence of a mineral acid or a heterogeneous catalyst. The adipic acid produces with the process may be low in metals and/or sulphates.

  本发明涉及一种从脂肪族酸二元酯制备己二酸的过程，包括：- 在水的存在下，使脂肪族酸二元酯发生水解反应，以适宜的温度和时间形成包含己二酸的水解产物；- 可选地从所述水解产物中回收己二酸，其特征在于在脂肪族酸的初始存在下进行水解反应，并进一步获得己二酸。本发明还涉及将己二酸用作脂肪族酸二元酯水解反应中的酸催化剂。该过程可以在缺乏矿酸或非均相催化剂的情况下优势地进行。通过该过程生产的己二酸可能含有较少的金属和/或硫酸盐。
