2-Chlorophenol Chemical Properties,Usage,Production

Chemical Properties

2-Chlorophenol is a colourless to light brown liquid, All isomers have a characteristic odor. It is used to make dyes and other chemicals, and as a disinfectant, bactericide, and germicide.

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

2-chlorophenol and 2,4-dichlorophenol are used in organic synthesis. 2-chlorophenol is utilized in the manufacture of dye-stulfs and in the process for extracting sulphur and nitrogen compounds from coal.

Preparation

0.5 mole of tert-butyl hypochlorite is dropped, with stirring, into a solution or suspension of the 0.5 mole of phenol in 150-300 ml of carbon tetrachloride, the temperature being allowed to rise to the boiling point of the solvent. The mixture is then boiled under reflux for a further 2 hours, the carbon tetrachloride and the tert-butyl alcohol are distilled off, and the residue is fractionated collecting fraction boiling at 174.9 °C.

Synthesis Reference(s)

The Journal of Organic Chemistry, 35, p. 528, 1970 DOI: 10.1021/jo00827a060
Tetrahedron Letters, 29, p. 1319, 1988 DOI: 10.1016/S0040-4039(00)80287-7

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.

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.
