2-Chlorophenol Chemical Properties,Uses,Production

Chemical Properties

colourless to light brown liquid

Chemical Properties

All isomers have a characteristic odor.

Physical properties

Pale amber liquid with a slight phenolic, floral, or musty-type odor. At 40 °C, the average and lowest odor concentrations detected were 0.36 and 0.088 μg/L, respectively. At 25 °C, the average taste threshold concentration and the lowest concentration at which a taste was detected were 0.97 and 0.94 μg/L, respectively (Young et al., 1996).

Uses

Organic synthesis (dyes).

General Description

A colorless to amber liquid with an unpleasant, penetrating odor. Density 1.265 g / cm3. Sinks in water and slowly dissolves. Freezing point 7°C (46°F). Boiling point 175°C (347°F).

Air & Water Reactions

Very soluble in water

Reactivity Profile

2-Chlorophenol is a weak acid. Neutralizes bases in exothermic reactions. Incompatible with oxidizing agents. Incompatible with acid chlorides and acid anhydrides. Forms ethers, esters and salts with metals and amines .

Hazard

Toxic by skin absorption, inhalation, or ingestion. Strong irritant to tissue.

Health Hazard

Poisonous; may be fatal if inhaled, swallowed or absorbed through skin. Irritating to skin and eyes; direct contact may cause burns. Rats receiving lethal doses via oral, subcutaneous or intraperitoneal routes displayed similar symptoms: restlessness, increased breathing rate and motor weakness followed by tremors, chronic convulsions, dyspnea, coma and death.

Safety Profile

Poison by ingestion, intraperitoneal, and intravenous routes. Experimental reproductive effects. Questionable carcinogen with experimental tumorigenic data. Mutation data reported. Flammable liquid when exposed to heat, flame, or oxidizers. To fight fire, use alcohol foam. When heated to decomposition it emits toxic fumes of Cl-. See also CHLOROPHENOLS and CHLORIDES.

Potential Exposure

Monochlorophenols are used in the manufacture of fungicides, slimicides, bactericides, pesticides, herbicides, disinfectants, wood and glue preservatives; in the production of phenolic resins; in the extraction of certain minerals from coal; as a denaturant for ethanol; as an antiseptic; as a disinfectant, and others.

Environmental Fate

Biological. Chloroperoxidase, a fungal enzyme isolated from Caldariomyces fumago, reacted with 2-chlorophenol yielding traces of 2,4,6-trichlorophenol, 2,4- and 2,6-dichlorophenols (Wannstedt et al., 1990). When 2-chlorophenol was statically incubated in the dark at 25 °C with yeast extract and settled domestic wastewater inoculum, significant biodegradation with rapid adaptation was observed. At concentrations of 5 and 10 mg/L, 86 and 83% biodegradation, respectively, were observed after 7 d (Tabak et al., 1981). Biodegradation rates of 10 and 8 μmol/L?d were reported for chlorophenol in saline water and acclimated sulfidogenic sediment cultures (H?ggblom and Young, 1990).
Soil. In laboratory microcosm experiments kept under aerobic conditions, half-lives of 7.2 and 1.7 d were reported for 2-chlorophenol in an acidic clay soil (<1% organic matter) and slightly basic sandy loam soil (3.25% organic matter) (Loehr and Matthews, 1992). In a nonsterile clay loam soil, a loss of 91% was reported when 2-chlorophenol was incubated in a nonsterile clay loam at 0 °C. Nondetectable levels of 2-chlorophenol was reported in sediments obtained from a stream at 20 °C after 10 to 15 d (Baker et al., 1980).
Surface Water. Hoigné and Bader (1983) reported 2-chlorophenol reacts with ozone at a rate constant of 1,100/M?sec at the pH range of 1.8 to 4.0.
Photolytic. Monochlorophenols exposed to sunlight (UV radiation) produced catechol and other hydroxybenzenes (Hwang et al., 1986). Titanium dioxide suspended in an aqueous solution and irradiated with UV light (λ = 365 nm) converted 2-chlorophenol to carbon dioxide at a significant rate (Matthews, 1986). In a similar experiment, irradiation of an aqueous solution containing 2- chlorophenol and titanium dioxide with UV light (λ >340 nm) resulted in the formation of chlorohydroquinone and trace amounts of catechol. Hydroxylation of both of these compounds forms the intermediate hydroxyhydroquinone, which degrades quickly to unidentified carboxylic acids and carbonyl compounds (D’Oliveira et al., 1990).
Chemical/Physical. Wet oxidation of 2-chlorophenol at 320 °C yielded formic and acetic acids (Randall and Knopp, 1980). Wet oxidation of 2-chlorophenol at elevated pressure and temperature yielded the following products: acetone, acetaldehyde, formic, acetic, maleic, oxalic, muconic, and succinic acids (Keen and Baillod, 1985).

Shipping

UN 2020 (solid); UN2021 (liquid) Chlorophenols, solid and liquid, Hazard Class: 6.1; Labels: 6.1-Poisonous materials.

Purification Methods

Pass 2-chlorophenol at least twice through a gas chromatography column. It has also been purified by fractional distillation. [Beilstein 6 IV 782.]

Incompatibilities

May form explosive mixture with air. Contact with oxidizing agents can cause fire and explosion hazard. Heat produces hydrogen chloride and chlorine. Corrosive to aluminum, copper and other chemically active metals.

Waste Disposal

Incinerate in admixture with flammable solvent in furnace equipped with afterburner and scrubber.
