    • A process for producing a hydrogenation product of aromatic carboxylic acid which comprises continuously producing the hydrogenation product of aromatic carboxylic acid by hydrogenating an aromatic carboxylic acid having a melting point of 250° C. or higher in a solvent in the presence of a solid catalyst, wherein the hydrogenation is conducted in a condition such that substantially the entire amount of the aromatic carboxylic acid of a raw material is dissolved in the solvent by recycling a portion of a reaction liquid taken out of a reactor into the reactor. An aromatic carboxylic acid having a high melting point and hardly soluble in solvents can be hydrogenated at a suitable reaction temperature in accordance with a continuous process without using a great amount of a solvent and the reaction product of the object compound can be produced very efficiently.
    • 一种芳族羧酸的氢化产物的制造方法,其特征在于,在固体催化剂存在下,通过在溶剂中氢化熔点为250℃以上的芳香族羧酸,连续制造芳香族羧酸的氢化物, 其特征在于,氢化反应是将从反应器中取出的反应液的一部分再循环到反应器中,将原料的芳香族羧酸的总量全部溶解在溶剂中的方式进行。 可以在不使用大量溶剂的情况下,根据连续方法在合适的反应温度下氢化不溶于溶剂的高熔点,并且可以非常有效地制备目标化合物的反应产物。
