Decomposition of ethylene

WebMajor industrial reactions of ethylene include in order of scale: 1) polymerization, 2) oxidation, 3) halogenation and hydrohalogenation, 4) alkylation, 5) hydration, 6) oligomerization, and 7) hydroformylation. Webdepolymerisation and decomposition of many polymers occurs in near-critical water. This allows one to use near-critical water to convert used polymeric materials into useful chemicals.
