    • PURPOSE: A method for preparing the hydrogenation product of an aromatic carbonic acid is provided to obtain the hydrogenation product with a high melting point and of being insoluble in solvent effectively without using a large amount of a solvent and at a suitable reaction temperature. CONSTITUTION: The method comprises the step of hydrogenating an aromatic carbonic acid with a melting point of 250 deg.C or more in a solvent in the presence of a solid catalyst to prepare the hydrogenation product of an aromatic carbonic acid continuously, wherein some ejected from a reactor is re-circulated into the reactor, thereby allowing the hydrogenation to be carried out in the state that the aromatic carbonic acid is practically dissolved in the solvent. Preferably the slurry obtained by dissolving the aromatic carbonic acid into the solvent is supplied into the reactor continuously. Preferably the aromatic carbonic acid is dicarbonic acid.
    • 目的:提供一种制备芳族碳酸氢化产物的方法,以获得高熔点的氢化产物,并且在不使用大量溶剂的情况下并且在合适的反应温度下不能溶解。 方案:该方法包括在固体催化剂存在下,在溶剂中,在250℃或更高的熔点下氢化芳族碳酸的步骤,以连续地制备芳族碳酸的氢化产物,其中一些从 将反应器再循环到反应器中,从而使芳烃碳酸实际上溶解在溶剂中进行氢化。 优选将通过将芳族碳酸溶解到溶剂中获得的浆料连续地供入反应器。 优选芳族碳酸是二碳酸。
