Usage

General Description

trans-1,2-Dichloroethylene is a chemical compound with the molecular formula C2H2Cl2. It is a colorless liquid with a sharp, sweet odor, and is used primarily as an intermediate in the production of other organic chemicals. It is also used as a solvent and as a component in some household products. trans-1,2-Dichloroethylene is considered a hazardous substance, as it can cause irritation to the skin, eyes, and respiratory system upon exposure. It is also classified as a potential carcinogen and is regulated in terms of its use, handling, and disposal to minimize environmental and health risks.

Reductive capacity of natural reductants

The reductive capacities of soil minerals and Silawa soil for Cr(VI) and chlorinated ethylenes were determined and characterized to understand in situ treatment using these natural reductions. The reductive capacity of soil minerals for Cr(VI) was 3-16 times greater than that for tetrachloroethylene (PCE), indicating that Cr(VI) is more susceptible to the reduction by soil minerals than PCE. Green rust (GRSO4) showed the greatest reductive capacity for Cr(VI) and PCE followed by magnetite, pyrite, biotite, montmorillonite, and vermiculite. The major transformation product in pyrite and GRSO4 suspensions was acetylene rather than dichloroethylene (DCE) and vinyl chloride (VC). For VC degradation, ethylene was the main transformation product with a low concentration of ethane observed. Fe(II) content in soil minerals was directly proportional to the reductive capacity of soil minerals for Cr(VI) and PCE, suggesting that Fe(II) content is an important factor that significantly affects reductive transformations of target contaminants in natural systems.

Method for recovering trans-1,2-dichloroethene

Describes a method for recovering trans-1,2-dichloroethene from a liquid feed composition comprising both the cis- and trans-isomers of 1,2-dichloroethene and contaminating amounts of other chlorinated hydrocarbons, e.g., lower alkyl chlorinated hydrocarbons, such as C1-C2 chlorinated hydrocarbons. In one of the described methods, the liquid feed composition is introduced into a first distillation column 10 wherein the stereoisomers and chlorinated hydrocarbons more volatile than the stereoisomers are removed as overhead 12 and charged to a second distillation column 20. In column 20, the stereoisomers are separated from the more volatile chlorinated hydrocarbons, and a bottoms fraction 24 comprising the stereoisomers are charged to a reaction distillation column 30 wherein the cis-isomer, is isomerized to the trans-isomer in the liquid phase and in the presence of an organic free-radical initiator, e.g., an azonitrile initiator. Substantially pure trans-1;2-dichloroethene is recovered as overhead 32 from reaction distillation column 30.
