英文摘要将可溶性Ru纳米粒子用于催化苯选择性加氢制备环己烯反应,考察了还原方法对Ru纳米粒子催化活性的影响;并以醇水还原法制备的Ru纳米粒子为催化剂,考察了温度和压力对反应性能的影响.当使用脱硫的苯作为原料时,苯转化率可达30.2%,环己烯选择性达到46.9%.以无水兰尼镍作催化剂,100℃时,环氧环己烷加氢转化率为100%,环己醇选择性为93.2%.从原料苯出发制得环己醇的单程收率可达14%,由此找到一条制备环己醇的新途径.; A new process to prepare cyclohexanol from benzene has been developed by a three-step approach. First, the benzene is selectively hydrogenated to cyclohexene by using soluble Ru nanoparticles as catalyst. Second, the epoxidation of cyclohexene can be achieved by literature methods. Then, in the end, the hydrogenation of cyclohexane oxide was performed by using anhydrous Raney-Ni as catalyst. It was found that in step one and three, the overall yield to produce cylohexanol from benzene reaches 14% under the optimized reaction conditions.; 北京市自然科学基金; SCI(E); 中文核心期刊要目总览(PKU); 中国科技核心期刊(ISTIC); 中国科学引文数据库(CSCD); 1; 1; 251-256; 34
