Production of aromatic compounds from fish residues

A pathway for synthesis of halobenzene via olefin metathesis of fish oils

Abstract

Six-membered ring compound 1,4-cyclohexadiene (1,4-CHD) was synthesized from fish oil containing EPA and DHA. The 1,4-CHD was then converted to bromobenzene by bromination followed by dehydrobromination. The use of a phase transfer catalyst was effective in the dehydrobromination, and no heating was required in all processes. Fish oil is a potential natural resource, and this study is aimed for a way to biomass shifts in the organic chemical industry
