Chlorobenzene biodegrades slowly in soil and aquifer material(6). 1-bromo-4-chloro-benzene. Chlorobenzene is an important industrial solvent and a widely used intermediate in production of commodities such as herbicides, dyestuffs, and rubber [ 1 ]. Application. The use of DDT in agriculture was banned in the 1970's, after its acute toxicity to humans and implications in breast cancer became concerns.

Hydrolysis is not expected to be an important environmental fate process since this compound lacks functional groups that hydrolyze under environmental conditions. On this Wikipedia the language links are at the top of the page across from the article title. Dichlorodiphenyltrichloroethane (DDT) is an organic compound that was once used as an insecticide in the early 1900's. However, biodegradatoin data are conflicting. The LD50 (oral, rats) is 756mg/kg. Chlorobenzene is a flammable liquid with a high vapor pressure and a medium solubility in water. Chlorobenzene appears as a colorless to clear, yellowish liquid with a sweet almond-like odor. Flash point 84F. Practically insoluble in water and somewhat denser than water (9.2 lb / gal). Vapors heavier than air. Used to make pesticides, dyes, and other chemicals.

There are also 3v and an S3 axis. p-chlorophenylbromide. Topics we will be exploring include its properties, how it is synthesized, reactions it undergoes, and uses of the compound. Some of it will dissolve in water, but it readily evaporates into air. Chlorobenzene may volatilize from dry soil surfaces based upon its vapor pressure. In this lesson we will be focussing on the organic compound known as chlorobenzene. Chlorobenzene's production and use as a chemical intermediate, solvent, and heat transfer medium may result in its release to the environment through various waste streams. Korry has a Ph.D. in organic chemistry and teaches college chemistry courses. At one time, chlorobenzene was the main precursor for the manufacture of phenol: C 6 H 5 Cl + NaOH C 6 H 5 OH + NaCl The reaction also has a byproduct of salt. The reaction is known as the Dow process, with the reaction carried out at 350 C using fused sodium hydroxide without solvent. Some of it will dissolve in water, but it readily evaporates into air.

(1,4) One of the most important properties of chlorobenzene is its polarity. It is a derivative of benzene with three chloride substituents. Vapor-phase chlorobenzene is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 21 days(SRC), calculated from its rate constant of 7.70X10-13 cu cm/molecule-sec at 25 deg C(3). A 0% of theoretical BOD using activated sludge in the Japanese MITI test classifies chlorobenzene as not readily biodegradable(7). Except where otherwise noted, data are given for materials in their standard state (at 25 C [77 F], 100 kPa). ?) Chlorobenzene is an aromatic organic compound with the chemical formula C 6 H 5 Cl. This colorless, flammable liquid is a common solvent and a widely used intermediate in the manufacture of other chemicals. [6] Due to the electronegative nature of the chlorine, when another group of atoms is attached to chlorobenzene, the new group will always go ortho (directly adjacent to the chlorine) or para (directly across from the chlorine). document.write(" ") Chlorobenzene is a colorless, flammable liquid with an aromatic, almond-like odor.

Volatilization of chlorobenzene from moist soil surfaces is expected to be an important fate process(SRC) given a Henry's Law constant of 3.11X10-3 atm-cu m/mole(4). A variety of aliphatic and aromatic amines can undergo the N-arylation with aryl chlorides using KOt-Bu as a base to give the respective products in high yield, and mono- or diphenylation of aniline is controllable by simply changing molar amounts of chlorobenzene (Table 1). The chlorobenzenes, particularly mono-, 1,2-di-, and 1,2,4-trichlorobenzene, are widely used as solvents in chemical reactions and to dissolve such special materials as oils, waxes, resins, greases, and rubber. Chlorobenzene is a useful compound for other organic reactions.
