    • PURPOSE: A process for preparing phthalides by hydrogenating phthalic acid anhydrides with hydrogen using suspended Raney-type catalysts are provided which enables easy recovery of catalysts and does not need a large quantity of catalysts and hydrogenation for many hours. CONSTITUTION: Phthalides of general formula (I), in which R1, R2, R3 and R4, independently of one another, designatehydrogen, C1-C4 alkyl or C1-C4 alkoxy, are prepared by hydrogenating phthalic acid anhydrides of general formula (II), in which the groups R1, R2, R3 and R4 have the above meanings, with hydrogen in the presence of suspended Raney-type catalysts in a hydrogenating device by mixing a liquid phase containing the catalyst and the phthalic acid anhydride used and the resultant phthalide and a gaseous phase containing the hydrogenating hydrogen using a mixing device which has a mixing output of at least 50 W/l in the liquid phase.
    • 目的:提供一种通过使用悬浮的阮内型催化剂用氢气氢化邻苯二甲酸酐制备邻苯二甲酸酯的方法,其能够容易地回收催化剂,并且不需要大量的催化剂和氢化许多小时。 构成:通式(I)的酞酸酯,其中R 1,R 2,R 3和R 4彼此独立地表示氢,C 1 -C 4烷基或C 1 -C 4烷氧基,通过氢化通式(II)的邻苯二甲酸酐制备, 其中基团R 1,R 2,R 3和R 4具有上述含义,在氢化装置中,在悬浮的阮内型催化剂存在下,通过混合含有催化剂的液相和所用的邻苯二甲酸酐和所得的苯酞 以及含有氢化氢的气相,其混合装置在液相中具有至少50W / l的混合输出。
