WebJan 1, 2012 · Using δ13C values determined for ethene and for chlorinated ethenes at a contaminated field site undergoing bioremediation, this study demonstrates how CSIA of ethene can be used to reduce uncertainty and risk at a site by distinguishing between actual mass balance deficits during reductive dechlorination and apparent lack of mass balance … WebDirect chlorination of ethylene is generally conducted in Hquid EDC in a bubble column reactor. Ethylene and chlorine dissolve in the Hquid phase and combine in a homogeneous catalytic reaction to form EDC. Under typical process conditions, the reaction rate is controlled by mass transfer, with absorption of ethylene as the limiting factor (77). WebIn this reaction, ethane is reacted with diatomic chlorine, a halogen. The reaction between an alkane and an elemental halogen, such as fluorine, chlorine, or bromine, is a substitution reaction. A substitution reaction is a type of reaction where a part of a molecule is removed and replaced with something else. dr nasra nj
