Cyclodimerization Of 1,3-Pentadiene With Homogeneous Nickel Catalyst, Morteza Soltani
Cyclodimerization Of 1,3-Pentadiene With Homogeneous Nickel Catalyst, Morteza Soltani
Retrospective Theses and Dissertations
Piperylene concentrate is a complex mixture of 5-carbon unsaturated hydrocarbons obtained as by-products when naptha or gas oils are cracked. The major component in this mixture is 1,3-pentadiene. The cyclodimerization of 1,3-pentadience in piperylene concentrate by using a nickel catalyst was studied. Various types of ligands were used in the preparation of the nickel catalyst. The effect of each ligand on activity of the catalyst in dimerization of diene, on conversion, and on yield of reaction were investigated. The effect of reaction conditions, such as temperature, pressure, and reaction time, on conversion of monomer, yield of dimer, and selectivity of …
