摘要:采用浸演法制备了负载型Ru-Y/TO2催化剂,并考察了其ぞ和、啃加、应中的催化性能。结果表
明,负载型Ru-Y/"TiO2催化剂对萜烯树脂加氢反应具有较高的催化
50℃点气压力4MPa,反应时
间6h,制得了无色或没色萜烯树脂,加氢反应前、后萜烯树脂的色共可内、以上,且催化剂稳定性较好,循
环使用5次后,其催化萜烯树脂加氢反应前后的色差仍高于75。合的色或浅色萜烯树脂具有无毒、稳
定和抗老化等特性,可广泛应用于塑料、油墨、涂料、貓合剂、电
食品工和医药材料等领域。

Abstract: The supported Ru-y/Ti ysts wa prepared by impregnation and characterized by XRD and SEM. The catalytic ac
tivity on the hydrogenat on of ene re colorless terpene resin was explored. The results indicated that, the hydrogenation of
terpene resin exhibited hig
ivity under the optimal reaction conditions as: terpene resin 1.000 g, 2.5%RU-2.5%Y/Tio
0.040 g, n-hexane 2 ml 0 MPA, 6color-dif erence of terpene resin was up to 82. 7%before and after hydrogenation. Mo-
reover, the products were conven htly eparated from the catalyst by simple decantation, and the catalyst could be reused five
times, the color-dif erence of erpd esin is higher 75% before and after hydrogenation. The decolorized terpene resins might be
used as plastics, ting inks, paining, adhesive, electronie prodcts, food processing and health goods because it was innoc
stable and agile tant
