In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Oxidative and reductive degradation of mixed contaminants by bifunctional aluminum, published in 2006-01-31, which mentions a compound: 542-58-5, Name is 2-Chloroethyl acetate, Molecular C4H7ClO2, COA of Formula: C4H7ClO2.
Transformation of various contaminants including carbon tetrachloride (CT), Me tert-Bu ether (MTBE), trichloroethylene (TCE), and bis(2-chloroethyl) ether (BCEE) using bifunctional aluminum was examined in batch reactors. Reductive degradation was observed only in reactions with CT while MTBE, TCE, and BCEE underwent oxidative pathways. In a batch reactor containing both CT and MTBE, oxidation of MTBE and reduction of CT by bifunctional aluminum took place simultaneously in the presence of oxygen. The MTBE was degraded to tert-Bu formate, tert-Bu alc., acetone, Me acetate, and isobutene while the reduction of CT produced chloroform and dichloromethane. This indicates that bifunctional aluminum has a dual functionality of decomposing both oxidatively and reductively degradable contaminants together. Aluminum metal serves as a reductant while oxygen acts as an oxidant. Oxidizing capacity of bifunctional aluminum, resulted from reductive activation of dioxygen (O2), is dependent on both oxygen level and effectiveness of reductants. It was found that the redox potential of reaction systems can function as a simple indicator to determine the oxidizing capacity of bifunctional aluminum.
