| 范存良; 杨忠保; 徐佩若(上海石油化工股份有限公司化工研究所; 华东理工大学化工学院) |
| 摘 要：研究了异戊二烯在两种金属催化作用下均相线性二聚生成月桂烯的影响因素 ,得到优惠工艺条件 :反应温度 13℃ ,催化剂∶异戊二烯 (mol/mol) =0 .0 5∶1 0 ,胺∶异戊二烯(mol/mol) =0 .0 7∶1.0。对加入失活剂的反应液进行蒸馏处理 ,常压下回收溶剂和未反应的异戊二烯 ,含量分别大于 98%和 96% ;在减压条件下分离出月桂烯 ,含量大于 90 %。回收的溶剂和异戊二烯可以再利用 ,月桂烯的总收率大于 4 0 % ,异戊二烯直接二聚合成月桂烯工艺简单 ,便于放大 |

| Abstract：The selective linear dimerization of isoprene to formate myrcene in a single phase catalyst solution prepared by mixing two metals, amine, solvent and a small content of isoprene was studied. The optimum conditions of the dimerization of isoprene were obtained∶t=13℃, the amount of catalyst was n(cat)∶m(IP)=0.05∶1.0, molar ratio of amine to isoprene was 0.07∶1.0. Myrcene, unreacted isoprene and solvent were separated form reactant by conventional distillations, the contents of recovered isoprene, solvent and... |
