摘 要:通过双环戊二烯与环戊二烯的齐聚反应合成了环戊二烯三聚体,考察了催化剂三苯基膦氯化镍(Ni(PPh3)2Cl2)的用量、反应温度、溶剂种类等条件对反应收率的影响,结果表明溶剂种类及反应温度对环戊二烯三聚体的选择性和收率影响显著。溶剂乙腈与环戊二烯(CPD)质量比为5时,摩尔比n(Ni(PPh3)2Cl2)∶n(Zn)∶n(CPD)为0.05∶0.6∶1时在60℃反应8 h,环戊二烯三聚体的收率为83.2%。齐聚法合成环戊二烯三聚体与Diels-Alder法相比,反应温度(60℃)和压力(0.1 MPa)大幅降低,收率显著提高。With a new method of the oligomerization of dicyclopentadiene and clopentadiene,a high density hydrocarbon fuel tri-cyclopentadiene was synthesized with a yield up to 83. 2%. The effects of catalyst amount,temperature,solvent on the reaction of TCPD was studied. Results show that the optimum conditions are the molar ratio of n(Ni(PPh3)2Cl2)∶ n(Zn)∶ n(CPD)=0. 05 ∶ 0. 6 ∶ 1,reaction temperature 60 ℃,and reaction time 8 h. With respect to the Diels-Alder method,the oligomerization method has lower reation temperature and pressure(0. 1 MPa),and higher yield.
