Synthesis of Mono and Polyolefins

Most of these come from heterogeneous catalytic processes. 

A demand for very high purity 1-butene as a comonomer in polyethylene production has created renewed interest in this application of alkene 

Multi-ton quantities of 1,5-hexadiene have been manufactured in alkene metathesis semi-works units and the process has been studied in a small specialty olefin pilot plant by the Phillips Company. Feedstocks for this process are the commerically available butadiene derivatives (1,5-cyclooc-tadiene and 1,5,9-cyclododecatriene). The use of excess ethylene and a
