Iridium Catalyst for Dehydrogenative Dimerization of Ethylene to Yield 1,3-Butadiene Schematic diagram of the catalytic dehydrogenative dimerization of ethylene to butadieneInvention Summary: 1,3-Butadiene is a chemical building block, most notably known for the production of synthetic elastomers and polymers. Traditionally, 1,3-butadiene is produced as a byproduct of naphtha cracking for ethylene production. Due to new sources, ethylene...

Synthesis of p-Xylene by Dehydroaromatization of 3-Methyleneheptane obtained from Ethylene Invention Summary:p-Xylene is mostly produced from cracking of naphtha, but there is a need for new and cost-effective methods for the production. Indeed, conventional p-xylene synthesis requires toluene separation from refinery gasoline streams; performing a disproportionation reaction to yield a benzene fraction and a mixed xylene fraction; and finally...
