General description
Ethylene (ET), a simple olefin, is an important synthetic reagent. It is also a plant hormone that regulates various physiological and developmental processes, such as ripening of fruit, abscission, senescence and responses to wounding in plants. Pd(II) and Ni(II)-based catalysts are reported to catalyze the polymerization of ET to afford high molecular weight polymers. Mechanism of Diels-Alder Reaction of 1,3-butadiene with ET has been investigated. Diels-Alder reaction between butadiene and ET, via concerted and the stepwise mechanisms has been investigated by ab initio MO methods. Dehydration of algae-produced ethanol to ET in the presence of nanoscale catalyst HZSM-5 (protonated Zeolite Socony Mobil-5) shows promising results in replacing fossil fuel methods for the industrial production of ET. The utility of microsized spent tea leaf powder (MSTLP) as an ethylene adsorbent has been investigated.
Application
Ethylene was used in the preparation of polyethylene (PE), by polymerization in the presence of titanium complexes having F(s) or CF3(s) containing phenoxy-imine chelate ligands.
