  A process for hydrogenating benzenepolycarboxylic acids or a derivatives thereof by bringing one or more benzenepolycarboxylic acids or derivatives thereof into contact with a hydrogen-containing gas is carried out in the presence of a catalyst containing macropores. The catalyst contains, as an active metal, at least one metal of transition group VIII of the Periodic Table alone or together with at least one metal of transition group I or VII of the Periodic Table. Except that hydrogenation of dimethyl terephthalate using a catalyst containing ruthenium as active metal, either alone or together with at least one metal of transition group I, VII or VIII of the Periodic Table, applied to a support having a mean pore diameter of at least 50 nm and a BET surface are of at most 30 m 2 /g, where the active metal is present in an amount of from 0.01 to 30% by weight, based on the total weight of the catalyst, and the ratio of the surface areas of the active metal and the catalyst support is less than 0.05, is excluded. Likewise, hydrogenation of dimethyl terephthalate using a catalyst containing ruthenium as active metal, either alone or together with at least one metal of transition group I, VII or VIII of the Periodic Table, applied to a support with from 10 to 50% pore volume formed by macropores with pore volumes from 50 nm to 10,000 nm, and 50 to 90% pore volume formed by mesopores with pore diameters from 2 to 50 nm, with the pore volumes adding up to 100%, where the active metal is present in an amount of from 0.01 to 30% by weight, based on the total weight of the catalyst, is also excluded. Further, novel hydrogenation products, obtainable by hydrogenating benzenepolycarboxylic acid and derivatives, as well as their use as plasticizers in plastics.

  一种通过使一种或多种苯聚羧酸或其衍生物与含氢气体接触而使苯聚羧酸或其衍生物氢化的工艺是在含有大孔的催化剂存在下进行的。催化剂中至少含有一种元素周期表第八过渡族金属作为活性金属，或至少含有一种元素周期表第一或第七过渡族金属。但使用含有钌作为活性金属的催化剂（单独或与至少一种元素周期表中过渡族 I、VII 或 VIII 金属一起）在平均孔径至少为 50 nm 且 BET 表面积至多为 30 m2 的载体上进行对苯二甲酸二甲酯的氢化，则不在此列。 2 /g，其中活性金属的含量为催化剂总重量的 0.01 至 30%（按重量计），且活性金属与催化剂载体的表面积之比小于 0.05。同样，使用含有作为活性金属的钌的催化剂进行对苯二甲酸二甲酯的氢化，该催化剂可单独使用，也可与元素周期表中过渡族 I、VII 或 VIII 中的至少一种金属一起使用，该催化剂应用于孔体积为 50 纳米至 10,000 纳米的大孔所形成的孔体积为 10%至 50%，孔直径为 2 至 50 纳米的中孔所形成的孔体积为 50%至 90%，孔体积相加达 100%的载体上，其中活性金属的含量为 0.也不包括活性金属含量为 0.01 至 30%（按催化剂总重量计）的催化剂。此外，还包括通过氢化苯聚羧酸及其衍生物而获得的新型氢化产品，以及它们在塑料中作为增塑剂的用途。

  C 9 to C 11 alkyl benzoates are used as plasticisers for polyvinyl chloride in particular in combination with plasticisers such as di-2-ethyl hexyl phthalate, diisononyl phthalate, di-2-propyl heptyl phthalate, diisodecyl phthalate or di-2-ethyl hexyl terephthalate. The use of the C 9 to C 11 alkyl benzoates provides low viscosity low volatility plasticisers, which are fast fusing with lower hot bench gelation temperature and which can be used to reduce the staining problems associated with use of di-2-ethyl hexyl phthalate and diisononyl phthalate. The low viscosity of the C 9 to C 11 alkyl benzoates allows the formulation of solvent free flexible PVC formulations meeting stringent VOC limitations.
