What does vinyl chloride degrade?

Under aerobic conditions, vinyl chloride was readily degraded, with greater than 99% of the labeled material being degraded after 108 days and approximately 65% being mineralized to 14CO2.

What are the breakdown products of TCE?

The spontaneous degradation of trichloroethylene epoxide can produce as many as four products: dichloroacetate, carbon monoxide, glyoxylate, and formate.

What does PCE degrade into?

The degradation process for PCE is generally PCE→TCE→cis-1,2-DCE (with the possibility of minor amounts of trans-1,2-DCE and 1,1-DCE)→VC→ethene. At each step, different types of degradation are possible.

How do you remove PCE from groundwater?

Remediating Groundwater Technologies for cleaning up PCE-contaminated groundwater include pump and treat, in situ bioremediation using injection of reducing compounds to promote bacterial breakdown of the chlorinated compounds, chemical oxidation, permeable reactive barriers (PRBs), and air sparging/SVE.

What is abiotic degradation?

Abiotic Degradation: It is a prominent process that mainly occurs under the influences of hydrolysis and photolysis. Hydrolysis: Hydrolytic reactions is the reaction of water with another chemical compound to form two or more products involving usually splitting the other compound.

What are the daughter products of PCE?

The primary daughter products include trichloroethylene (TCE), cis-1,2-dichloroethylene (cis-DCE), trans-1,2-dichloroethylene (trans-DCE), and vinyl chloride (VC). The daughter products can be as dangerous to human health and the environment as PCE (in some cases, more dangerous).

Does PCE degrade to TCE?

PCE, for example, though strictly non-biodegradable under aerobic conditions, can be microbially transformed to TCE, cis-dichloroethylene (cDCE), vinyl chloride (VC), and ethene in a highly reducing ground water environment.

How do you remove TCE from water?

Treatment options are available to remove trichloroethylene from well water. The most commonly used option is granular activated carbon filtration. 1 Options include central treatment (at the well or at entry to home) or a point-of-use device (kitchen sink filter).

How do you dispose of Perchloroethylene?

Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber; Contaminated packaging: Dispose of as unused product. Sigma-Aldrich; Safety Data Sheet for Tetrachloroethylene. Product Number: 371696, Version 4.11 (Revision Date 06/28/2017).

What products have vinyl chloride?

Vinyl chloride is an intermediate in the production of PVC plastic used in a wide range of products including pipes, wire and cable coatings, packaging materials, upholstery for automobiles and furniture, wall and floor coverings, flooring, backing for carpet, house wares, automotive parts, medical devices, and …
