General description

Ethylene (ET), a simple olefin, is an important synthetic reagent. It is also a plant hormone[1] that regulates various physiological and developmental processes, such as ripening of fruit, abscission, senescence and responses to wounding in plants.[2] Pd(II) and Ni(II)-based catalysts are reported to catalyze the polymerization of ET to afford high molecular weight polymers.[3] Mechanism of Diels-Alder Reaction of 1,3-butadiene with ET has been investigated.[4] Diels-Alder reaction between butadiene and ET, via concerted and the stepwise mechanisms has been investigated by ab initio MO methods.[5] 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.[6] The utility of microsized spent tea leaf powder (MSTLP) as an ethylene adsorbent has been investigated.[7]

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.[8]
