Abstract: 采用SRNA-4非晶态合金催化剂对双环戊二烯(DCPD)进行了加氢反应考察,研究了搅拌速度、温度、压力和催化剂浓度各条件对双环戊二烯加氢反应的影响.结果表明DCPD加氢反应为连串反应,中间产物主要为9,10-二氢双环戊二烯(9,10-DHDCPD)和少量1,2-二氢双环戊二烯(1,2-DHDCPD);DCPD易于加氢生成中间产物9,10-DHDCPD,其继续加氢为四氢双环戊二烯(endo-THDCPD)需要较为剧烈的条件.DCPD加氢过程选用两段法,第一段为温度110℃,第二段为130℃,压力均为1.5MPa,催化剂浓度1.18%.非晶态合金(催化剂)对DCPD的加氢反应活性明显高于Raney Ni,可进行1、2位加氢反应生成1,2-DHDCPD,并且催化剂用量少,反应温度和反应压力低,反应时间短,生成副产物少.
