| 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... |
