2022年4月28日 · Chlorinated solvents are organic compounds generally constructed of a simple hydrocarbon chain (typically one to three carbon atoms in length). They can be divided into three categories based on their structural characteristics: chlorinated methanes, chlorinated ethanes and chlorinated ethenes.

Organochlorine chemistry is concerned with the properties of organochlorine compounds, or organochlorides, organic compounds that contain one or more carbon–chlorine bonds. [1] The chloroalkane class ( alkanes with one or more hydrogens substituted by chlorine) includes common examples.

2022年10月14日 · Chlorinated solvents, also known as organochlorines, are chemicals primarily used as raw materials in the production of other products. They may be produced as byproducts or intermediates in the synthesis of other chlorinated materials.

Compared to other organic solvents, chlorinated organics exhibit unique chemical properties such as high solvency, non-flammability, low boiling point, and high vapor density. Chlorinated organics are remarkably stable, noncorrosive to most metals, and have low rates of evaporation and low vapor pressures.

2020年12月22日 · Chlorinated solvents were once, and in many places are still, ubiquitous in chemistry laboratories. This review explores the properties that led to such widespread use, why there is now an increasing drive to minimize usage, and what alternatives are currently available.

2014年10月1日 · Chlorinated volatile organic compounds (Cl-VOCs), including polychloromethanes, polychloroethanes and polychloroethylenes, are widely used as solvents, degreasing agents and a variety of commercial products.

Chlorinated solvents, such as methylene chloride, PCE, and TCE are some of the most commonly identified organic chemicals in groundwater found at EPA Superfund sites (USGS, 2006).

Raw (untreated) water may contain a large number of compounds that can react with chlorine species, including inorganic reducing agents (H 2 S, SO 3 2−, NO 2−, Fe 2+ and Mn 2+, which are oxidized to, for example, SO 4 2−, NO 3−, Fe 3+ and MnO 2), ammonia and amino-nitrogen groups; and organic substances.

2024年12月1日 · We investigate the molecular composition and formation mechanism of chlorinated DOM during electrochemical oxidation process of biologically treated leachate DOM. At a current density of 8 mA/cm 2, after 120 min of electrolysis, 479 unknown chlorinated DOMs were detected in the treated effluent, comprising 21.55% of the total.

2024年12月5日 · This article reviews the sources, occurrences, and transformation mechanisms for chlorinated organic pollutants (Cl-OPs) from petrochemical industry, including chlorinated volatile organic compounds, traditional and emerging persistent organic pollutants (POPs).
